+# Contributing
+
+Thank you for your interest in contributing to the `clio` project 🙏
+
+## Workflow
+
+To contribute, please:
+
+1. Fork the repository under your own user.
+2. Create a new branch on which to commit/push your changes.
+3. Write and test your code.
+4. Ensure that your code compiles with the provided build engine and update the provided build engine as part of your PR where needed and where appropriate.
+5. Where applicable, write test cases for your code and include those in the relevant subfolder under `tests`.
+6. Ensure your code passes [automated checks](#pre-commit-hooks)
+7. Squash your commits (i.e. rebase) into as few commits as is reasonable to describe your changes at a high level (typically a single commit for a small change). See below for more details.
+8. Open a PR to the main repository onto the _develop_ branch, and follow the provided template.
+
+> **Note:** Please read the [Style guide](#style-guide).
+
+### `git lfs` hooks
+
+Install `git lfs` hooks using the following command:
+
+```bash
+git lfs install
+```
+
+> **Note:** You need to install Git LFS hooks before installing `pre-commit` hooks.
+
+### `pre-commit` hooks
+
+To ensure code quality and style, we use [`pre-commit`](https://pre-commit.com/).
+
+Run the following command to enable `pre-commit` hooks that help with Clio development:
+
+```bash
+pip3 install pre-commit
+pre-commit install --hook-type pre-commit --hook-type pre-push
+```
+
+`pre-commit` takes care of running each tool in [`.pre-commit-config.yaml`](https://github.com/XRPLF/clio/blob/develop/.pre-commit-config.yaml) in a separate environment.
+
+`pre-commit` also attempts to automatically use Doxygen to verify that everything public in the codebase has doc comments.
+If Doxygen is not installed, the hook issues a warning and recommends installing Doxygen for future commits.
+
+### Git commands
+
+This sections offers a detailed look at the git commands you will need to use to get your PR submitted.
+Please note that there are more than one way to do this and these commands are provided for your convenience.
+At this point it's assumed that you have already finished working on your feature/bug.
+
+> **Important:** Before you issue any of the commands below, please hit the `Sync fork` button and make sure your fork's `develop` branch is up-to-date with the main `clio` repository.
+
+```bash
+# Create a backup of your branch
+git branch <your feature branch>_bk
+
+# Rebase and squash commits into one
+git checkout develop
+git pull origin develop
+git checkout <your feature branch>
+git rebase -i develop
+```
+
+For each commit in the list other than the first one, enter `s` to squash.
+After this is done, you will have the opportunity to write a message for the squashed commit.
+
+> **Hint:** Please use **imperative mood** in the commit message, and capitalize the first word.
+
+```bash
+# You should now have a single commit on top of a commit in `develop`
+git log
+```
+
+> **Note:** If there are merge conflicts, please resolve them now.
+
+```bash
+# Use the same commit message as you did above
+git commit -m 'Your message'
+git rebase --continue
+```
+
+> **Important:** If you have no GPG keys set up, please follow [this tutorial](https://docs.github.com/en/authentication/managing-commit-signature-verification/adding-a-gpg-key-to-your-github-account)
+
+```bash
+# Sign the commit with your GPG key, and push your changes
+git commit --amend -S
+git push --force
+```
+
+### Use ccache (optional)
+
+Clio uses `ccache` to speed up compilation. If you want to use it, please make sure it is installed on your machine.
+CMake will automatically detect it and use it if it is available.
+
+### Opening a pull request
+
+When a pull request is open CI will perform checks on the new code.
+Title of the pull request and squashed commit should follow [conventional commits specification](https://www.conventionalcommits.org/en/v1.0.0/).
+
+### Fixing issues found during code review
+
+While your code is in review, it's possible that some changes will be requested by reviewer(s).
+This section describes the process of adding your fixes.
+
+We assume that you already made the required changes on your feature branch.
+
+```bash
+# Add the changed code
+git add <paths to add>
+
+# Add a [FOLD] commit message (so you remember to squash it later)
+# while also signing it with your GPG key
+git commit -S -m "[FOLD] Your commit message"
+
+# And finally push your changes
+git push
+```
+
+### After code review
+
+When your PR is approved and ready to merge, use `Squash and merge`.
+The button for that is near the bottom of the PR's page on GitHub.
+
+> **Important:** Please leave the automatically-generated mention/link to the PR in the subject line **and** in the description field add `"Fix #ISSUE_ID"` (replacing `ISSUE_ID` with yours) if the PR fixes an issue.
+> **Note:** See [issues](https://github.com/XRPLF/clio/issues) to find the `ISSUE_ID` for the feature/bug you were working on.
+
+## Style guide
+
+This is a non-exhaustive list of recommended style guidelines. These are not always strictly enforced and serve as a way to keep the codebase coherent.
+
+### Formatting
+
+Code must conform to `clang-format`, unless the result is unreasonably difficult to read or maintain.
+In most cases the `pre-commit` hook takes care of formatting and fixes any issues automatically.
+To manually format your code, run `pre-commit run clang-format --files <your changed files>` for C++ files, and `pre-commit run cmake-format --files <your changed files>` for CMake files.
+
+### Documentation
+
+All public namespaces, classes and functions must be covered by doc (`doxygen`) comments. Everything that is not within a nested `impl` namespace is considered public.
+
+> **Note:** Keep in mind that this is enforced by Clio's CI and your build will fail if newly added public code lacks documentation.
+
+### Avoid
+
+- Proliferation of nearly identical code.
+- Proliferation of new files and classes unless it improves readability or/and compilation time.
+- Unmanaged memory allocation and raw pointers.
+- Macros (unless they add significant value.)
+- Lambda patterns (unless these add significant value.)
+- CPU or architecture-specific code unless there is a good reason to include it, and where it is used guard it with macros and provide explanatory comments.
+- Importing new libraries unless there is a very good reason to do so.
+
+### Seek to
+
+- Extend functionality of existing code rather than creating new code.
+- Prefer readability over terseness where important logic is concerned.
+- Inline functions that are not used or are not likely to be used elsewhere in the codebase.
+- Use clear and self-explanatory names for functions, variables, structs and classes.
+- Use TitleCase for classes, structs and filenames, camelCase for function and variable names, lower case for namespaces and folders.
+- Provide as many comments as you feel that a competent programmer would need to understand what your code does.
+
+## Maintainers
+
+Maintainers are ecosystem participants with elevated access to the repository. They are able to push new code, make decisions on when a release should be made, etc.
+
+### Code Review
+
+A PR must be reviewed and approved by at least one of the maintainers before it can be merged.
+
+### Adding and Removing
+
+New maintainers can be proposed by two existing maintainers, subject to a vote by a quorum of the existing maintainers. A minimum of 50% support and a 50% participation is required. In the event of a tie vote, the addition of the new maintainer will be rejected.
+
+Existing maintainers can resign, or be subject to a vote for removal at the behest of two existing maintainers. A minimum of 60% agreement and 50% participation are required. The XRP Ledger Foundation will have the ability, for cause, to remove an existing maintainer without a vote.

-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.

+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 does not connect to the peer to peer network. Instead, clio extracts data from a specified rippled node. Running clio requires access to a rippled node
-from which data can be extracted. The rippled node does not need to be running on the same machine as clio.

+## 📡 Clio and `rippled`
 
-## Requirements
-1. Access to a Cassandra cluster or ScyllaDB cluster. Can be local or remote.
+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, such as information about queued transactions, is also not returned.
 
-2. Access to one or more rippled nodes. Can be local or remote.
+Clio retrieves data from a designated group of `rippled` nodes instead of connecting to the peer-to-peer network.
+For requests that require access to the peer-to-peer 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`.
 
-## Building
-clio is built with cmake. clio requires c++20, and boost 1.75.0 or later. protobuf v2 is required and must be manually built on systems that ship with v3, including Debian 11 and Ubuntu 21.10.
-Use these instructions to build a clio executable from source. These instructions were tested on Ubuntu 20.04 LTS.
+> [!NOTE]
+> Clio requires access to at least one `rippled` node, which can run on the same machine as Clio or separately.

+## 📚 Learn more about Clio
 
-## Running
-`./clio_server config.json`
+Below are some useful docs to learn more about Clio.
 
-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
+**For Developers**:
 
-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
+- [How to build Clio](./docs/build-clio.md)
+- [Coverage report](./docs/coverage-report.md)
 
-The example configs of rippled and clio are setup 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.
+**For Operators**:
 
-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.
+- [How to configure Clio and rippled](./docs/configure-clio.md)
+- [How to run Clio](./docs/run-clio.md)
+- [Logging](./docs/logging.md)
+- [Troubleshooting guide](./docs/trouble_shooting.md)
 
-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
-is 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.
+**General reference material:**
 
-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.
+- [API reference](https://xrpl.org/http-websocket-apis.html)
+- [Developer docs](https://xrplf.github.io/clio)
+- [Clio documentation](https://xrpl.org/the-clio-server.html#the-clio-server)
 
-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.
+## 🆘 Help
 
-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.

-**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.

-# How to review clio
-Clio is a massive project, and thus I don't expect the code to be reviewed the
-way a normal PR would. So I put this guide together to help reviewers look at
-the relevant pieces of code without getting lost in the weeds.
-
-One thing reviewers should keep in mind is that most of clio is designed to be
-lightweight and simple. We try not to introduce any uneccessary complexity and
-keep the code as simple and straightforward as possible. Sometimes complexity is
-unavoidable, but simplicity is the goal.
-
-## Order of review
-The code is organized into 4 main components, each with their own folder. The
-code in each folder is as self contained as possible. A good way to approach
-the review would be to review one folder at a time.
-
-### backend
-The code in the backend folder is the heart of the project, and reviewers should
-start here. This is the most complex part of the code, as well as the most
-performance sensitive. clio does not keep any data in memory, so performance
-generally depends on the data model and the way we talk to the database.
-
-Reviewers should start with the README in this folder to get a high level idea
-of the data model and to review the data model itself. Then, reviewers should
-dive into the implementation. The table schemas and queries for Cassandra are 
-defined in `CassandraBackend::open()`. The table schemas for Postgres are defined
-in Pg.cpp. The queries for Postgres are defined in each of the functions of `PostgresBackend`.
-A good way to approach the implementation would be to look at the table schemas,
-and then go through the functions declared in `BackendInterface`. Reviewers could
-also branch out to the rest of the code by looking at where these functions are
-called from.
-
-### webserver
-The code in the webserver folder implements the web server for handling RPC requests.
-This code was mostly copied and pasted from boost beast example code, so I would
-really appreciate review here.
-
-### rpc
-The rpc folder contains all of the handlers and any helper functions they need.
-This code is not too complicated, so reviewers don't need to dwell long here.
-
-### etl
-The etl folder contains all of the code for extracting data from rippled. This
-code is complex and important, but most of this code was just copied from rippled
-reporting mode, and thus has already been reviewed and is being used in prod.
-
-## Design decisions that should be reviewed
-
-### Data model
-Reviewers should review the general data model. The data model itself is described
-at a high level in the README in the backend folder. The table schemas and queries
-for Cassandra are defined in the `open()` function of `CassandraBackend`. The table
-schemas for Postgres are defined in Pg.cpp. 
-
-Particular attention should be paid to the keys table, and the problem that solves
-(successor/upper bound). I originally was going to have a special table for book_offers,
-but then I decided that we could use the keys table itself for that and save space.
-This makes book_offers somewhat slow compared to rippled, though still very usable.
-
-### Large rows
-I did some tricks with Cassandra to deal with very large rows in the keys and account_tx
-tables. For each of these, the partition key (the first component of the primary
-key) is a compound key. This is meant to break large rows into smaller rows. This
-is done to avoid hotspots. Data is sharded in Cassandra, and if some rows get very
-large, some nodes can have a lot more data than others.
-
-For account_tx, this has performance implications when iterating very far back
-in time. Refer to the `fetchAccountTransactions()` function in `CassandraBackend`.
-
-It is unclear if this needs to be done for other tables.
-
-### Postgres table partitioning
-Originally, Postgres exhibited performance problems when the dataset approach 1
-TB. This was solved by table partitioning.
-
-### Threading
-I used asio for multithreading. There are a lot of different io_contexts lying
-around the code. This needs to be cleaned up a bit. Most of these are really
-just ways to submit an async job to a single thread. I don't think it makes
-sense to have one io_context for the whole application, but some of the threading
-is a bit opaque and could be cleaned up.
-
-### Boost Json
-I used boost json for serializing data to json.
-
-### No cache
-As of now, there is no cache. I am not sure if a cache is even worth it. A
-transaction cache would not be hard, but a cache for ledger data will be hard.
-While a cache would improve performance, it would increase memory usage. clio
-is designed to be lightweight. Also, I've reached thousands of requests per
-second with a single clio node, so I'm not sure performance is even an issue.
-
-## Things I'm less than happy about
-
-#### BackendIndexer
-This is a particularly hairy piece of code that handles writing to the keys table.
-I am not too happy with this code. Parts of it need to execute in real time as
-part of ETL, and other parts are allowed to run in the background. There is also
-code that detects if a previous background job failed to complete before the
-server shutdown, and thus tries to rerun that job. The code feels tacked on, and
-I would like it to be more cleanly integrated with the rest of the code.
-
-#### Shifting
-There is some bit shifting going on with the keys table and the account_tx table.
-The keys table is written to every 2^20 ledgers. Maybe it would be better to just
-write every 1 million ledgers. 
-
-#### performance of book_offers
-book_offers is a bit slow. It could be sped up in a variety of ways. One is to
-keep a separate book_offers table. However, this is not straightforward and will
-use more space. Another is to keep a cache of book_offers for the most recent ledger
-(or few ledgers). I am not sure if this is worth it
-
-#### account_tx in Cassandra
-After the fix to deal with large rows, account_tx can be slow at times when using
-Cassandra. Specifically, if there are large gaps in time where the account was
-not affected by any transactions, the code will be reading empty records. I would
-like to sidestep this issue if possible.
-
-#### Implementation of fetchLedgerPage
-`fetchLedgerPage()` is rather complex. Part of this seems unavoidable, since this
-code is dealing with the keys table.

+#
+# 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:
+
+- ccache 4.11.3
+- clang 16.0.6
+- ClangBuildAnalyzer 1.6.0
+- conan 2.17.0
+- doxygen 1.12
+- gcc 12.3.0
+- gh 2.74
+- git-cliff 2.9.1
+- 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.
+`ASan`, `TSan` and `UBSan` sanitizer builds are enabled via conan profiles for each of the supported compilers.
+These can be selected using the following pattern (all lowercase): `[compiler].[sanitizer]` (e.g. `--profile:all gcc.tsan`).
