 [XRP](https://xrpl.org/xrp.html) is a public, counterparty-free crypto-asset native to the XRP Ledger, and is designed as a gas token for network services and to bridge different currencies. XRP is traded on the open-market and is available for anyone to access. The XRP Ledger was created in 2012 with a finite supply of 100 billion units of XRP.

+- Read the markdown files in the source tree: `src/ripple/**/*.md`.
 - Read [the levelization document](.github/scripts/levelization) to get an idea of the internal dependency graph.
 - In the big picture, the `main` function constructs an `ApplicationImp` object, which implements the `Application` virtual interface. Almost every component in the application takes an `Application&` parameter in its constructor, typically named `app` and stored as a member variable `app_`. This allows most components to depend on any other component.

 This program allows us to recognize and reward individuals or groups that identify and report bugs. In summary, in order to qualify for a bounty, the bug must be:

 2. **Relevant**. A security issue, posing a danger to user funds, privacy, or the operation of the XRP Ledger.
 3. **Original and previously unknown**. Bugs that are already known and discussed in public do not qualify. Previously reported bugs, even if publicly unknown, are not eligible.
 4. **Specific**. We welcome general security advice or recommendations, but we cannot pay bounties for that.

+## Dependencies
+
+Install these dependencies:
+
+- [Doxygen](http://www.doxygen.nl): All major platforms have [official binary
+  distributions](http://www.doxygen.nl/download.html#srcbin), or you can
+  build from [source](http://www.doxygen.nl/download.html#srcbin).
+  - MacOS: We recommend installing via Homebrew: `brew install doxygen`.
+    The executable will be installed in `/usr/local/bin` which is already
+    in the default `PATH`.
+
+    If you use the official binary distribution, then you'll need to make
+    Doxygen available to your command line. You can do this by adding
+    a symbolic link from `/usr/local/bin` to the `doxygen` executable. For
+    example,
+
+    ```
+    $ ln -s /Applications/Doxygen.app/Contents/Resources/doxygen /usr/local/bin/doxygen
+    ```
+
+- [PlantUML](http://plantuml.com):
+  1. Install a functioning Java runtime, if you don't already have one.
+  2. Download [`plantuml.jar`](http://sourceforge.net/projects/plantuml/files/plantuml.jar/download).
+
+- [Graphviz](https://www.graphviz.org):
+  - Linux: Install from your package manager.
+  - Windows: Use an [official installer](https://graphviz.gitlab.io/_pages/Download/Download_windows.html).
+  - MacOS: Install via Homebrew: `brew install graphviz`.
+
+## Docker
+
+Instead of installing the above dependencies locally, you can use the official
+build environment Docker image, which has all of them installed already.
+
+1. Install [Docker](https://docs.docker.com/engine/installation/)
+2. Pull the image:
+
+```
+sudo docker pull rippleci/rippled-ci-builder:2944b78d22db
+```
+
+3. Run the image from the project folder:
+
+```
+sudo docker run -v $PWD:/opt/rippled --rm rippleci/rippled-ci-builder:2944b78d22db
+```
+
+## Build
+
+There is a `docs` target in the CMake configuration.
+
+```
+mkdir build
+cd build
+cmake -Donly_docs=ON ..
+cmake --build . --target docs --parallel
+```
+
+The output will be in `build/docs/html`.
