Install Addons

For development purposes, it is best to checkout the addons repos under an "addons" directory, and make an J folder name ~Addons that points to that directory.

To checkout a complete list, see the addonrepos repository, which has the current repository list and an installer for linux and macos.

Install From Github

To install a package/addon directly from Github, it is possible to do. See: https://code.jsoftware.com/wiki/Pacman#github
