# Marian NMT code documentation and library API
This directory contains code documentation and library API for developers of Marian NMT.
The documentation is generated using
[Sphinx](https://www.sphinx-doc.org/en/master/usage/quickstart.html) +
[Breathe](https://breathe.readthedocs.io/en/latest/directives.html) +
[Doxygen](http://www.doxygen.nl/manual/docblocks.html) +
[Exhale](https://exhale.readthedocs.io/en/latest/usage.html).
The documentation source code is written in `.rst` or `.md` files with special directives that allow
to reference to C++ source code and documentation. The source documents are then build into static
HTML pages.
## Installation
On Ubuntu 20.04, install the following packages:
sudo apt-get install python3 python3-pip python3-setuptools doxygen
Then set up a Python environment and install modules:
pip3 install virtualenv
virtualenv venv -p python3
source venv/bin/activate
pip install -r requirements.txt
Documentation building should also work on Windows, but it has not been tested.
## Generation
The documentation can be generated by running:
make html
The website will be generated into `build/html` and accessible by opening _index.html_ in your
browser.
Directories:
- `build` - automatically output directory for HTML documentation
- `doxygen` - automatically generated Doxygen XML files
- `api` - automatic library API generated with Exhale
- `.rst` and `.md` files in this directory and its subdirectories are documentation source files
- `_static` - custom CSS and JavaScript files
