The plugin can be loaded by specifying the repo to a package manager like any other, for example by cloning it in a
subdirectory of `'packpath'` or using one of the many plugin managers.
#{foldMap githubPlugin github}

Since the plugin is written in Haskell with the
[Ribosome](https://hackage.haskell.org/package/ribosome/docs/Ribosome.html) framework, its executable has to be
