Nexus Git provides access to Git repositories in Roblox Studio. It uses existing project structures (like Rojo) to allow developers who don't use external editors to contribute to Git-based repositories.
Development of Nexus Git by the repository owner has been stopped due to the estimated time required to make Nexus Git robust enough to keep using. Bug fixes are still supported but feature requests will not be implemented. Pull requests are still accepted. Additionally, two-way syncing is an option in Rojo 0.6.
Documentation for the server and the client (Roblox Studio Plugin) can be found on the GitHub pages for this project. The docs folder can also be used since it has all of the markdown files.
The server is provided as releases for Windows x86-64, OS X x86-64, and Linux x86-64 under the GitHub releases and the client is sold as a Roblox Studio plugin. If you need to build either, whether it is to try the plugin or build for a different platform (like Windows x86, Linux ARM, etc), see the building documentation.
Both issues and pull requests are accepted for this project. More information can be found here.
Nexus Git doesn't have any major alternatives for handling exporting files from Roblox Studio to the file system. Although, an alternative workflow exists of using external editors and syncing into Roblox Studio. See Rojo's repository for more information about this, as well as alternatives to Rojo.
