 ## Installation Notes
-Though this is the initial public debut, it is still an overall early release of MUTN/libmutton. Because of this, no distribution packages are provided as of yet. Please see the [install guide](https://github.com/rwinkhart/MUTN/blob/main/wiki/MUTN/install.md) for help installing or building MUTN in its current state (as well as getting started).
+Though this is the initial public debut, it is still an overall early release of MUTN/libmutton. Because of this, no distribution packages are provided as of yet. MUTN is, however, available as a source package from the AUR as "mutn". Please see the [install guide](https://github.com/rwinkhart/MUTN/blob/main/wiki/install.md) for help installing or building MUTN in its current state (as well as getting started).
 
 Note that libmuttonserver, libmutton, and MUTN have not yet been separated into their own respective repos (this will be done for v0.2.1). As such, libmuttonserver is built with the `noMarkdown` build tag to avoid pulling in Glamour and its dependencies.
