Current documentation is built on top of Sphinx documentation generator. It is released under the terms of the Creative Commons BY-NC-ND 4.0 International License.
We're folllowing GitFlow:
masterbranch for the curent major stable release,developbranch for next major release.
GLPI installation documentation is currently visible on ReadTheDocs.
You'll just have to install Python Sphinx, it is generally available in distributions repositories for Linux.
If your distribution does not provide it, you could use a virtualenv:
$ virtualenv /path/to/virtualenv/files
$ /path/to/virtualenv/bin/activate
$ pip install sphinx
Once all has been successfully installed, just run the following to build the documentation:
$ make html
Results will be avaiable in the build/html directory :)
Note that it actually uses the default theme, which differs locally and on readthedocs system.
