-# CHANGES:
-#
-# 2012-01-31, Lars Bilke
-# - Enable Code Coverage
-#
-# 2013-09-17, Joakim Söderberg
-# - Added support for Clang.
-# - Some additional usage instructions.
-#
-# 2016-02-03, Lars Bilke
-# - Refactored functions to use named parameters
-#
-# 2017-06-02, Lars Bilke
-# - Merged with modified version from github.com/ufz/ogs
-#
-# 2019-05-06, Anatolii Kurotych
-# - Remove unnecessary --coverage flag
-#
-# 2019-12-13, FeRD (Frank Dana)
-# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
-#   of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
-# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
-# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
-# - Set lcov basedir with -b argument
-# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
-#   overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
-# - Delete output dir, .info file on 'make clean'
-# - Remove Python detection, since version mismatches will break gcovr
-# - Minor cleanup (lowercase function names, update examples...)
-#
-# 2019-12-19, FeRD (Frank Dana)
-# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
-#
-# 2020-01-19, Bob Apthorpe
-# - Added gfortran support
-#
-# 2020-02-17, FeRD (Frank Dana)
-# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
-#   in EXCLUDEs, and remove manual escaping from gcovr targets
-#
-# 2021-01-19, Robin Mueller
-# - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run
-# - Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional
-#   flags to the gcovr command
-#
-# 2020-05-04, Mihchael Davis
-#     - Add -fprofile-abs-path to make gcno files contain absolute paths
-#     - Fix BASE_DIRECTORY not working when defined
-#     - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
-#
-# 2021-05-10, Martin Stump
-#     - Check if the generator is multi-config before warning about non-Debug builds
-#
-# 2022-02-22, Marko Wehle
-#     - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
-#       This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".
-#
-# 2022-09-28, Sebastian Mueller
-#     - fix append_coverage_compiler_flags_to_target to correctly add flags
-#     - replace "-fprofile-arcs -ftest-coverage" with "--coverage" (equivalent)
-#
-# 2023-12-15, Bronek Kozicki
-#     - remove setup_target_for_coverage_lcov (slow) and setup_target_for_coverage_fastcov (no support for Clang)
-#     - fix Clang support by adding find_program( ... llvm-cov )
-#     - add Apple Clang support by adding execute_process( COMMAND xcrun -f llvm-cov ... )
-#     - add CODE_COVERAGE_GCOV_TOOL to explicitly select gcov tool and disable find_program
-#     - replace both functions setup_target_for_coverage_gcovr_* with single setup_target_for_coverage_gcovr
-#     - add support for all gcovr output formats
-#
-# USAGE:
-#
-# 1. Copy this file into your cmake modules path.
-#
-# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
-#    using a CMake option() to enable it just optionally):
-#      include(CodeCoverage)
-#
-# 3. Append necessary compiler flags for all supported source files:
-#      append_coverage_compiler_flags()
-#    Or for specific target:
-#      append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
-#
-# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
-#
-# 4. If you need to exclude additional directories from the report, specify them
-#    using full paths in the COVERAGE_EXCLUDES variable before calling
-#    setup_target_for_coverage_*().
-#    Example:
-#      set(COVERAGE_EXCLUDES
-#          '${PROJECT_SOURCE_DIR}/src/dir1/*'
-#          '/path/to/my/src/dir2/*')
-#    Or, use the EXCLUDE argument to setup_target_for_coverage_*().
-#    Example:
-#      setup_target_for_coverage_gcovr(
-#          NAME coverage
-#          EXECUTABLE testrunner
-#          EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
-#
-# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
-#     relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
-#     Example:
-#       set(COVERAGE_EXCLUDES "dir1/*")
-#       setup_target_for_coverage_gcovr(
-#           NAME coverage
-#           EXECUTABLE testrunner
-#           FORMAT html-details
-#           BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
-#           EXCLUDE "dir2/*")
-#
-# 4.b If you need to pass specific options to gcovr, specify them in
-#     GCOVR_ADDITIONAL_ARGS variable.
-#     Example:
-#       set (GCOVR_ADDITIONAL_ARGS --exclude-throw-branches --exclude-noncode-lines -s)
-#       setup_target_for_coverage_gcovr(
-#           NAME coverage
-#           EXECUTABLE testrunner
-#           EXCLUDE "src/dir1" "src/dir2")
-#
-# 5. Use the functions described below to create a custom make target which
-#    runs your test executable and produces a code coverage report.
-#
-# 6. Build a Debug build:
-#      cmake -DCMAKE_BUILD_TYPE=Debug ..
-#      make
-#      make my_coverage_target

+Clio is an XRP Ledger API server optimized for RPC calls over WebSocket or JSON-RPC.
+It stores validated historical ledger and transaction data in a more space efficient format, and uses up to 4 times less space than [rippled](https://github.com/XRPLF/rippled).
 
-Clio offers the full rippled API, with the caveat that Clio by default only returns validated data.
-This means that `ledger_index` defaults to `validated` instead of `current` for all requests.
-Other non-validated data is also not returned, such as information about queued transactions.
-For requests that require access to the p2p network, such as `fee` or `submit`, Clio automatically forwards the request to a rippled node and propagates the response back to the client. 
-To access non-validated data for *any* request, simply add `ledger_index: "current"` to the request, and Clio will forward the request to rippled.

+Multiple Clio nodes can share access to the same dataset, which allows for a highly available cluster of Clio nodes without the need for redundant data storage or computation.
 
-Clio does not connect to the peer-to-peer network. Instead, Clio extracts data from a group of specified rippled nodes. Running Clio requires access to at least one rippled node
-from which data can be extracted. The rippled node does not need to be running on the same machine as Clio.

+## 🆘 Help
 
-## Help
 Feel free to open an [issue](https://github.com/XRPLF/clio/issues) if you have a feature request or something doesn't work as expected.
-If you have any questions about building, running, contributing, using clio or any other, you could always start a new [discussion](https://github.com/XRPLF/clio/discussions).
-
-## Requirements
-1. Access to a Cassandra cluster or ScyllaDB cluster. Can be local or remote.
-2. Access to one or more rippled nodes. Can be local or remote.
-
-## Building
-
-Clio is built with CMake and uses Conan for managing dependencies. 
-It is written in C++20 and therefore requires a modern compiler.
-
-## Prerequisites 
-
-### Minimum Requirements
-
-- [Python 3.7](https://www.python.org/downloads/)
-- [Conan 1.55](https://conan.io/downloads.html)
-- [CMake 3.16](https://cmake.org/download/)
-- [**Optional**] [GCovr](https://gcc.gnu.org/onlinedocs/gcc/Gcov.html) (needed for code coverage generation)
-- [**Optional**] [CCache](https://ccache.dev/) (speeds up compilation if you are going to compile Clio often)
-
-| Compiler    | Version |
-|-------------|---------|
-| GCC         | 11      |
-| Clang       | 14      |
-| Apple Clang | 14.0.3  |
-
-### Conan configuration
-
-Clio does not require anything but default settings in your (`~/.conan/profiles/default`) Conan profile. It's best to have no extra flags specified. 
-> Mac example:
-```
-[settings]
-os=Macos
-os_build=Macos
-arch=armv8
-arch_build=armv8
-compiler=apple-clang
-compiler.version=14
-compiler.libcxx=libc++
-build_type=Release
-compiler.cppstd=20
-```
-> Linux example:
-```
-[settings]
-os=Linux
-os_build=Linux
-arch=x86_64
-arch_build=x86_64
-compiler=gcc
-compiler.version=11
-compiler.libcxx=libstdc++11
-build_type=Release
-compiler.cppstd=20
-```
-
-### Artifactory
-
-1. Make sure artifactory is setup with Conan
-```sh
-conan remote add --insert 0 conan-non-prod http://18.143.149.228:8081/artifactory/api/conan/conan-non-prod
-```
-Now you should be able to download prebuilt `xrpl` package on some platforms.
-
-You might need to edit the `~/.conan/remotes.json` file to ensure that this newly added artifactory is listed last. Otherwise you might see compilation errors when building the project with gcc version 13 (or newer).
-
-2. Remove old packages you may have cached: 
-```sh 
-conan remove -f xrpl
-```
-
-## Building Clio
-
-Navigate to Clio's root directory and perform
-```sh
-mkdir build && cd build
-conan install .. --output-folder . --build missing --settings build_type=Release -o tests=True -o lint=False
-cmake -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release ..
-cmake --build . --parallel 8 # or without the number if you feel extra adventurous
-```
-If all goes well, `conan install` will find required packages and `cmake` will do the rest. you should end up with `clio_server` and `clio_tests` in the `build` directory (the current directory).
-
-> **Tip:** You can omit the `-o tests=True` in `conan install` command above if you don't want to build `clio_tests`.
-
-> **Tip:** To generate a Code Coverage report, include `-o coverage=True` in the `conan install` command above, along with `-o tests=True` to enable tests. After running the `cmake` commands, execute `make clio_tests-ccov`. The coverage report will be found at `clio_tests-llvm-cov/index.html`.
-
-## Building Clio with Docker
-
-It is possible to build Clio using docker if you don't want to install all the dependencies on your machine.
-```sh
-docker run -it rippleci/clio_ci:latest
-git clone https://github.com/XRPLF/clio
-mkdir build && cd build
-conan install .. --output-folder . --build missing --settings build_type=Release -o tests=True -o lint=False
-cmake -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release ..
-cmake --build . --parallel 8 # or without the number if you feel extra adventurous
-```
-
-## Running
-```sh
-./clio_server config.json
-```
-
-Clio needs access to a rippled server. The config files of rippled and Clio need
-to match in a certain sense.
-Clio needs to know:
-- the IP of rippled
-- the port on which rippled is accepting unencrypted WebSocket connections
-- the port on which rippled is handling gRPC requests
-
-rippled needs to open:
-- a port to accept unencrypted websocket connections
-- a port to handle gRPC requests, with the IP(s) of Clio specified in the `secure_gateway` entry
-
-The example configs of rippled and Clio are setups such that minimal changes are
-required. When running locally, the only change needed is to uncomment the `port_grpc`
-section of the rippled config. When running Clio and rippled on separate machines,
-in addition to uncommenting the `port_grpc` section, a few other steps must be taken:
-1. change the `ip` of the first entry of `etl_sources` to the IP where your rippled
-server is running
-2. open a public, unencrypted WebSocket port on your rippled server
-3. change the IP specified in `secure_gateway` of `port_grpc` section of the rippled config
-to the IP of your Clio server. This entry can take the form of a comma-separated list if
-you are running multiple Clio nodes.
-
-
-In addition, the parameter `start_sequence` can be included and configured within the top level of the config file. This parameter specifies the sequence of first ledger to extract if the database is empty. Note that ETL extracts ledgers in order and that no backfilling functionality currently exists, meaning Clio will not retroactively learn ledgers older than the one you specify. Choosing to specify this or not will yield the following behavior:
-- If this setting is absent and the database is empty, ETL will start with the next ledger validated by the network. 
-- If this setting is present and the database is not empty, an exception is thrown.
-
-In addition, the optional parameter `finish_sequence` can be added to the json file as well, specifying where the ledger can stop.
-
-To add `start_sequence` and/or `finish_sequence` to the config.json file appropriately, they will be on the same top level of precedence as other parameters (such as `database`, `etl_sources`, `read_only`, etc.) and be specified with an integer. Here is an example snippet from the config file:
-
-```json
-"start_sequence": 12345,
-"finish_sequence": 54321
-```
-
-The parameters `ssl_cert_file` and `ssl_key_file` can also be added to the top level of precedence of our Clio config. `ssl_cert_file` specifies the filepath for your SSL cert while `ssl_key_file` specifies the filepath for your SSL key. It is up to you how to change ownership of these folders for your designated Clio user. Your options include:
-- Copying the two files as root somewhere that's accessible by the Clio user, then running `sudo chown` to your user
-- Changing the permissions directly so it's readable by your Clio user
-- Running Clio as root (strongly discouraged)
-
-An example of how to specify `ssl_cert_file` and `ssl_key_file` in the config:
-
-```json
-"server": {
-    "ip": "0.0.0.0",
-    "port": 51233
-},
-"ssl_cert_file": "/full/path/to/cert.file",
-"ssl_key_file": "/full/path/to/key.file"
-```
-
-Once your config files are ready, start rippled and Clio. It doesn't matter which you
-start first, and it's fine to stop one or the other and restart at any given time.
-
-Clio will wait for rippled to sync before extracting any ledgers. If there is already
-data in Clio's database, Clio will begin extraction with the ledger whose sequence
-is one greater than the greatest sequence currently in the database. Clio will wait
-for this ledger to be available. Be aware that the behavior of rippled is to sync to
-the most recent ledger on the network, and then backfill. If Clio is extracting ledgers
-from rippled, and then rippled is stopped for a significant amount of time and then restarted, rippled
-will take time to backfill to the next ledger that Clio wants. The time it takes is proportional
-to the amount of time rippled was offline for. Also be aware that the amount rippled backfills
-are dependent on the online_delete and ledger_history config values; if these values
-are small, and rippled is stopped for a significant amount of time, rippled may never backfill
-to the ledger that Clio wants. To avoid this situation, it is advised to keep history
-proportional to the amount of time that you expect rippled to be offline. For example, if you
-expect rippled to be offline for a few days from time to time, you should keep at least
-a few days of history. If you expect rippled to never be offline, then you can keep a very small
-amount of history.
-
-Clio can use multiple rippled servers as a data source. Simply add more entries to
-the `etl_sources` section. Clio will load balance requests across the servers specified
-in this list. As long as one rippled server is up and synced, Clio will continue
-extracting ledgers.
-
-In contrast to rippled, Clio will answer RPC requests for the data already in the
-database as soon as the server starts. Clio doesn't wait to sync to the network, or
-for rippled to sync.
-
-When starting Clio with a fresh database, Clio needs to download a ledger in full.
-This can take some time, and depends on database throughput. With a moderately fast
-database, this should take less than 10 minutes. If you did not properly set `secure_gateway`
-in the `port_grpc` section of rippled, this step will fail. Once the first ledger
-is fully downloaded, Clio only needs to extract the changed data for each ledger,
-so extraction is much faster and Clio can keep up with rippled in real-time. Even under
-intense load, Clio should not lag behind the network, as Clio is not processing the data,
-and is simply writing to a database. The throughput of Clio is dependent on the throughput
-of your database, but a standard Cassandra or Scylla deployment can handle
-the write load of the XRP Ledger without any trouble. Generally the performance considerations
-come on the read side, and depends on the number of RPC requests your Clio nodes
-are serving. Be aware that very heavy read traffic can impact write throughput. Again, this
-is on the database side, so if you are seeing this, upgrade your database.
-
-It is possible to run multiple Clio nodes that share access to the same database.
-The Clio nodes don't need to know about each other. You can simply spin up more Clio
-nodes pointing to the same database as you wish, and shut them down as you wish.
-On startup, each Clio node queries the database for the latest ledger. If this latest
-ledger does not change for some time, the Clio node begins extracting ledgers
-and writing to the database. If the Clio node detects a ledger that it is trying to
-write has already been written, the Clio node will backoff and stop writing. If later
-the Clio node sees no ledger written for some time, it will start writing again.
-This algorithm ensures that at any given time, one and only one Clio node is writing
-to the database.
-
-It is possible to force Clio to only read data, and to never become a writer.
-To do this, set `read_only: true` in the config. One common setup is to have a
-small number of writer nodes that are inaccessible to clients, with several
-read only nodes handling client requests. The number of read only nodes can be scaled
-up or down in response to request volume.
-
-When using multiple rippled servers as data sources and multiple Clio nodes,
-each Clio node should use the same set of rippled servers as sources. The order doesn't matter.
-The only reason not to do this is if you are running servers in different regions, and
-you want the Clio nodes to extract from servers in their region. However, if you
-are doing this, be aware that database traffic will be flowing across regions,
-which can cause high latencies. A possible alternative to this is to just deploy
-a database in each region, and the Clio nodes in each region use their region's database.
-This is effectively two systems.
-
-Clio supports API versioning as [described here](https://xrpl.org/request-formatting.html#api-versioning).
-It's possible to configure `minimum`, `maximum` and `default` version like so:
-```json
-"api_version": {
-    "min": 1,
-    "max": 2,
-    "default": 1
-}
-```
-All of the above are optional.
-Clio will fallback to hardcoded defaults when not specified in the config file or configured values are outside
-of the minimum and maximum supported versions hardcoded in `src/rpc/common/APIVersion.h`.
-> **Note:** See `example-config.json` for more details. 
-
-## Admin rights for requests
-
-By default clio checks admin privileges by IP address from request (only `127.0.0.1` is considered to be an admin).
-It is not very secure because the IP could be spoofed.
-For a better security `admin_password` could be provided in the `server` section of clio's config:
-```json
-"server": {
-    "admin_password": "secret"
-}
-```
-If the password is presented in the config, clio will check the Authorization header (if any) in each request for the password.
-The Authorization header should contain type `Password` and the password from the config, e.g. `Password secret`.
-Exactly equal password gains admin rights for the request or a websocket connection.
-
-## Prometheus metrics collection
-
-Clio natively supports Prometheus metrics collection. It accepts Prometheus requests on the port configured in `server` section of config.
-Prometheus metrics are enabled by default. To disable it add `"prometheus": { "enabled": false }` to the config.
-It is important to know that clio responds to Prometheus request only if they are admin requests, so Prometheus should be configured to send admin password in header.
-There is an example of docker-compose file, Prometheus and Grafana configs in [examples/infrastructure](examples/infrastructure).
-
-## Using clang-tidy for static analysis
-
-Minimum clang-tidy version required is 17.0.
-Clang-tidy could be run by cmake during building the project.
-For that provide the option `-o lint=True` for `conan install` command:
-```sh
-conan install .. --output-folder . --build missing --settings build_type=Release -o tests=True -o lint=True
-```
-By default cmake will try to find clang-tidy automatically in your system.
-To force cmake use desired binary set `CLIO_CLANG_TIDY_BIN` environment variable as path to clang-tidy binary.
-E.g.:
-```sh
-export CLIO_CLANG_TIDY_BIN=/opt/homebrew/opt/llvm@17/bin/clang-tidy
-```
-
-## Coverage report
-
-Coverage report is intended for the developers using compilers GCC
-or Clang (including Apple Clang). It is generated by the build target `coverage_report`,
-which is only enabled when both `tests` and `coverage` options are set, e.g. with
-`-o coverage=True -o tests=True` in `conan`
-
-Prerequisites for the coverage report:
-
-- [gcovr tool](https://gcovr.com/en/stable/getting-started.html) (can be installed e.g. with `pip install gcovr`)
-- `gcov` for GCC (installed with the compiler by default) or
-- `llvm-cov` for Clang (installed with the compiler by default, also on Apple)
-- `Debug` build type
-
-Coverage report is created when the following steps are completed, in order:
-
-1. `clio_tests` binary built with the instrumentation data, enabled by the `coverage`
-   option mentioned above
-2. completed run of unit tests, which populates coverage capture data
-3. completed run of `gcovr` tool (which internally invokes either `gcov` or `llvm-cov`)
-   to assemble both instrumentation data and coverage capture data into a coverage report
-
-Above steps are automated into a single target `coverage_report`. The instrumented
-`clio_tests` binary can be also used for running regular unit tests. In case of a
-spurious failure of unit tests, it is possile to re-run `coverage_report` target without
-rebuilding the `clio_tests` binary (since it is simply a dependency of the coverage report target).
-
-The default coverage report format is `html-details`, but the developers
-can override it to any of the formats listed in `CMake/CodeCoverage.cmake`
-by setting `CODE_COVERAGE_REPORT_FORMAT` variable in `cmake`. For example, CI
-is setting this parameter to `xml` for the [codecov](codecov.io) integration.
-
-In case if some unit tests predictably fail e.g. due to absence of a Cassandra database, it is possible
-to set unit tests options in `CODE_COVERAGE_TESTS_ARGS` cmake variable, as demonstrated below:
-
-```
-cd .build
-conan install .. --output-folder . --build missing --settings build_type=Debug -o tests=True -o coverage=True
-cmake -DCODE_COVERAGE_REPORT_FORMAT=json-details -DCMAKE_BUILD_TYPE=Debug -DCODE_COVERAGE_TESTS_ARGS="--gtest_filter=-BackendCassandra*" -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake ..
-cmake --build . --target coverage_report
-```
-
-After `coverage_report` target is completed, the generated coverage report will be
-stored inside the build directory, as either of:
-
-- file named `coverage_report.*`, with a suitable extension for the report format, or
-- directory named `coverage_report`, with `index.html` and other files inside, for `html-details` or `html-nested` report formats.
-
-
-## Developing against `rippled` in standalone mode
-
-If you wish you develop against a `rippled` instance running in standalone
-mode there are a few quirks of both clio and rippled you need to keep in mind.
-You must:
-
-1. Advance the `rippled` ledger to at least ledger 256
-2. Wait 10 minutes before first starting clio against this standalone node.
-
-## Logging
-Clio provides several logging options, all are configurable via the config file and are detailed below.
-
-`log_level`: The minimum level of severity at which the log message will be outputted by default.
-Severity options are `trace`, `debug`, `info`, `warning`, `error`, `fatal`. Defaults to `info`.
-
-`log_format`: The format of log lines produced by clio. Defaults to `"%TimeStamp% (%SourceLocation%) [%ThreadID%] %Channel%:%Severity% %Message%"`.
-Each of the variables expands like so
-- `TimeStamp`: The full date and time of the log entry
-- `SourceLocation`: A partial path to the c++ file and the line number in said file (`source/file/path:linenumber`)  
-- `ThreadID`: The ID of the thread the log entry is written from
-- `Channel`: The channel that this log entry was sent to
-- `Severity`: The severity (aka log level) the entry was sent at
-- `Message`: The actual log message
-
-`log_channels`: An array of json objects, each overriding properties for a logging `channel`. 
-At the moment of writing, only `log_level` can be overriden using this mechanism.
-
-Each object is of this format:
-```json
-{
-    "channel": "Backend",
-    "log_level": "fatal"
-}
-``` 
-If no override is present for a given channel, that channel will log at the severity specified by the global `log_level`.
-Overridable log channels: `Backend`, `WebServer`, `Subscriptions`, `RPC`, `ETL` and `Performance`.
-
-> **Note:** See `example-config.json` for more details. 
-
-`log_to_console`: Enable/disable log output to console. Options are `true`/`false`. Defaults to true.
-
-`log_directory`: Path to the directory where log files are stored. If such directory doesn't exist, Clio will create it. If not specified, logs are not written to a file.
-
-`log_rotation_size`: The max size of the log file in **megabytes** before it will rotate into a smaller file. Defaults to 2GB.
-
-`log_directory_max_size`: The max size of the log directory in **megabytes** before old log files will be
-deleted to free up space. Defaults to 50GB.
-
-`log_rotation_hour_interval`: The time interval in **hours** after the last log rotation to automatically
-rotate the current log file. Defaults to 12 hours.
-
-Note, time-based log rotation occurs dependently on size-based log rotation, where if a
-size-based log rotation occurs, the timer for the time-based rotation will reset.
-
-`log_tag_style`: Tag implementation to use. Must be one of:
-- `uint`: Lock free and threadsafe but outputs just a simple unsigned integer 
-- `uuid`: Threadsafe and outputs a UUID tag
-- `none`: Don't use tagging at all
-
-## Cassandra / Scylla Administration
-
-Since Clio relies on either Cassandra or Scylla for its database backend, here are some important considerations:
-
-- Scylla, by default, will reserve all free RAM on a machine for itself. If you are running `rippled` or other services on the same machine, restrict its memory usage using the `--memory` argument: https://docs.scylladb.com/getting-started/scylla-in-a-shared-environment/
+If you have any questions about building, running, contributing, using Clio or any other, you could always start a new [discussion](https://github.com/XRPLF/clio/discussions).

-To build and run `clio_server`, follow the instructions in [README.md](https://github.com/XRPLF/clio).
-
-If you find issues or have a new idea, please open [an issue](https://github.com/XRPLF/clio/issues).
-
-# Releases
-
-## 0.1.0
-
-Clio is an XRP Ledger API server. Clio is optimized for RPC calls, over websocket or JSON-RPC. Validated historical ledger and transaction data is stored in a more space efficient format, using up to 4 times less space than rippled.
-
-Clio uses Cassandra or ScyllaDB, allowing for scalable read throughput. Multiple clio nodes can share access to the same dataset, allowing for a highly available cluster of clio nodes, without the need for redundant data storage or computation.
-
-**0.1.0** is the first beta of Project Clio. It contains:
--  `./src/backend` is the BackendInterface. This provides an abstraction for reading and writing information to a database.
--  `./src/etl` is the ReportingETL. The classes in this folder are used to extract information from the P2P network and write it to a database, either locally or over the network.
--  `./src/rpc` contains RPC handlers that are called by clients. These handlers should expose the same API as rippled.
--  `./src/subscriptions` contains the SubscriptionManager. This manages publishing to clients subscribing to streams or accounts.
--  `./src/webserver` contains a flex server that handles both http/s and ws/s traffic on a single port.
--  `./unittests` simple unit tests that write to and read from a database to verify that the ETL works.

+# CHANGES:
+#
+# 2012-01-31, Lars Bilke - Enable Code Coverage
+#
+# 2013-09-17, Joakim Söderberg - Added support for Clang. - Some additional usage instructions.
+#
+# 2016-02-03, Lars Bilke - Refactored functions to use named parameters
+#
+# 2017-06-02, Lars Bilke - Merged with modified version from github.com/ufz/ogs
+#
+# 2019-05-06, Anatolii Kurotych - Remove unnecessary --coverage flag
+#
+# 2019-12-13, FeRD (Frank Dana) - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor of
+# tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments. - CMake 3.4+: All excludes can be specified
+# relative to BASE_DIRECTORY - All setup functions: accept BASE_DIRECTORY, EXCLUDE list - Set lcov basedir with -b
+# argument - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be overridden with NO_DEMANGLE option
+# in setup_target_for_coverage_lcovr().) - Delete output dir, .info file on 'make clean' - Remove Python detection,
+# since version mismatches will break gcovr - Minor cleanup (lowercase function names, update examples...)
+#
+# 2019-12-19, FeRD (Frank Dana) - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
+#
+# 2020-01-19, Bob Apthorpe - Added gfortran support
+#
+# 2020-02-17, FeRD (Frank Dana) - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters in EXCLUDEs,
+# and remove manual escaping from gcovr targets
+#
+# 2021-01-19, Robin Mueller - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run -
+# Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional flags to the gcovr command
+#
+# 2020-05-04, Mihchael Davis - Add -fprofile-abs-path to make gcno files contain absolute paths - Fix BASE_DIRECTORY not
+# working when defined - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
+#
+# 2021-05-10, Martin Stump - Check if the generator is multi-config before warning about non-Debug builds
+#
+# 2022-02-22, Marko Wehle - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output
+# respectively. This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS,
+# e.g. GCOVR_ADDITIONAL_ARGS "--txt".
+#
+# 2022-09-28, Sebastian Mueller - fix append_coverage_compiler_flags_to_target to correctly add flags - replace
+# "-fprofile-arcs -ftest-coverage" with "--coverage" (equivalent)
+#
+# 2023-12-15, Bronek Kozicki - remove setup_target_for_coverage_lcov (slow) and setup_target_for_coverage_fastcov (no
+# support for Clang) - fix Clang support by adding find_program( ... llvm-cov ) - add Apple Clang support by adding
+# execute_process( COMMAND xcrun -f llvm-cov ... ) - add CODE_COVERAGE_GCOV_TOOL to explicitly select gcov tool and
+# disable find_program - replace both functions setup_target_for_coverage_gcovr_* with single
+# setup_target_for_coverage_gcovr - add support for all gcovr output formats
+#
+# USAGE:
+#
+# 1. Copy this file into your cmake modules path.
+#
+# 1. Add the following line to your CMakeLists.txt (best inside an if-condition using a CMake option() to enable it just
+#   optionally): include(CodeCoverage)
+#
+# 1. Append necessary compiler flags for all supported source files: append_coverage_compiler_flags() Or for specific
+#   target: append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
+#
+# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
+#
+# 1. If you need to exclude additional directories from the report, specify them using full paths in the
+#   COVERAGE_EXCLUDES variable before calling setup_target_for_coverage_*(). Example: set(COVERAGE_EXCLUDES
+# '${PROJECT_SOURCE_DIR}/src/dir1/*'
+# '/path/to/my/src/dir2/*') Or, use the EXCLUDE argument to setup_target_for_coverage_*(). Example:
+# setup_target_for_coverage_gcovr( NAME coverage EXECUTABLE testrunner EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*"
+# "/path/to/my/src/dir2/*")
+#
+# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set relative to the BASE_DIRECTORY (default:
+# PROJECT_SOURCE_DIR) Example: set(COVERAGE_EXCLUDES "dir1/*") setup_target_for_coverage_gcovr( NAME coverage EXECUTABLE
+# testrunner FORMAT html-details BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src" EXCLUDE "dir2/*")
+#
+# 4.b If you need to pass specific options to gcovr, specify them in GCOVR_ADDITIONAL_ARGS variable. Example: set
+# (GCOVR_ADDITIONAL_ARGS --exclude-throw-branches --exclude-noncode-lines -s) setup_target_for_coverage_gcovr( NAME
+# coverage EXECUTABLE testrunner EXCLUDE "src/dir1" "src/dir2")
+#
+# 1. Use the functions described below to create a custom make target which runs your test executable and produces a code
+#   coverage report.
+#
+# 1. Build a Debug build: cmake -DCMAKE_BUILD_TYPE=Debug .. make make my_coverage_target

+# CI image for XRPLF/clio
+
+This image contains an environment to build [Clio](https://github.com/XRPLF/clio), check code and documentation.
+It is used in [Clio Github Actions](https://github.com/XRPLF/clio/actions) but can also be used to compile Clio locally.
+
+The image is based on Ubuntu 20.04 and contains:
+- clang 16
+- gcc 12.3
+- doxygen 1.10
+- gh 2.40
+- ccache 4.8.3
+- conan
+- and some other useful tools
+
+Conan is set up to build Clio without any additional steps. There are two preset conan profiles: `clang` and `gcc` to use corresponding compiler.

+# Clio official docker image
+
+[Clio](https://github.com/XRPLF/clio) is an XRP Ledger API server optimized for RPC calls over WebSocket or JSON-RPC.
+It stores validated historical ledger and transaction data in a space efficient format.
+
+This image contains `clio_server` binary allowing users to run Clio easily.
+
+## Clio configuration file
+
+Please note that while Clio requires a configuration file, this image doesn't include any default config.
+Your configuration file should be mounted under the path `/opt/clio/etc/config.json`.
+Clio repository provides an [example](https://github.com/XRPLF/clio/blob/develop/docs/examples/config/example-config.json) of the configuration file.
+
+Config file recommendations:
+- Set `log_to_console` to `false` if you want to avoid logs being written to `stdout`.
+- Set `log_directory` to `/opt/clio/log` to store logs in a volume.
+
+## Usage
+
+The following command can be used to run Clio in docker (assuming server's port is `51233` in your config):
+```bash
+docker run -d -v <path to your config.json>:/opt/clio/etc/config.json -v <path to store logs>:/opt/clio/log -p 51233:51233 rippleci/clio
