For easy installation, use the prebuilt app bundle.

To run the git-annex assistant, just install the app, look for the icon, and start it up.

To use git-annex at the command line, you can add to your PATH

Alternatively, from the command line you can run, which makes your shell use all the programs bundled inside the app, including not just git-annex, but git, and several more. Handy if you don't otherwise have git installed.


An autobuild is also available, thanks to the Datalad project.
