Please refer to the list of known issues, and make sure you have backups of your work before trying it out.
From version 0.19 onwards, the location of the plugin has moved to Assets/Plugins/GitHub. If you have version 0.18 or lower, you need to delete the Assets/Editor/GitHub folder before you install newer versions. You should exit Unity and delete the folder from Explorer/Finder, as Unity will not unload native libraries while it's running. Also, remember to update your .gitignore file.
Please read the How to Build document for information on how to build GitHub for Unity.
The CONTRIBUTING.md document will help you get setup and familiar with the source. The documentation folder also contains more resources relevant to the project.
