-> You can omit the `-o '&:tests=True'` if you don't want to build `clio_tests`.
+2. Install dependencies through conan.

 ### Generating API docs for Clio
 
 The API documentation for Clio is generated by [Doxygen](https://www.doxygen.nl/index.html). If you want to generate the API documentation when building Clio, make sure to install Doxygen 1.12.0 on your system.
 
-To generate the API docs:
+To generate the API docs, please use CMake option `-Ddocs=ON` as described above and build the `docs` target.
 
-1. First, include `-o '&:docs=True'` in the conan install command. For example:

+Open the `index.html` file in your browser to see the documentation pages.
 
-   ```sh
-   mkdir build && cd build
-   conan install .. --output-folder . --build missing --settings build_type=Release -o '&:tests=True' -o '&:docs=True'
-   ```
-
-2. Once that has completed successfully, run the `cmake` command and add the `--target docs` option:
-
-   ```sh
-   cmake -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release ..
-   cmake --build . --parallel 8 --target docs
-   ```
-
-3. Go to `build/docs/html` to view the generated files.
-
-   Open the `index.html` file in your browser to see the documentation pages.

 ## Building Clio with Docker
 
 It is also possible to build Clio using [Docker](https://www.docker.com/) if you don't want to install all the dependencies on your machine.
 
 ```sh
-docker run -it ghcr.io/xrplf/clio-ci:latest

-mkdir build && cd build
-conan install .. --output-folder . --build missing --settings build_type=Release -o '&:tests=True'
-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

 ```
 
+Follow the same steps in the [Building Clio](#building-clio) section. You can use `--profile:all gcc` or `--profile:all clang` with the `conan install` command to choose the desired compiler.

-# Logging
-
-Clio provides several logging options, which all are configurable via the config file. These are detailed in the following sections.
-
-## `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`.
-
-> [!IMPORTANT]
-> At the time of writing, only `log_level` can be overridden 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`.
-
-The log channels that can be overridden are: `Backend`, `WebServer`, `Subscriptions`, `RPC`, `ETL` and `Performance`.
-
-> [!NOTE]
-> See [example-config.json](../docs/examples/config/example-config.json) for more details.
-
-## `log_to_console`
-
-Enable or disable log output to console. Options are `true`/`false`. This option 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 the option is not specified, the 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]
-> Log rotation based on time occurs in conjunction with size-based log rotation. For example, 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`: Doesn't use tagging at all
