 ## Requirements
 
-If you plan on using [AutoPkg](https://github.com/autopkg/autopkg), release 2.2 or greater is required as earlier versions do not have Munki repo plugin support.
+If you plan on using [AutoPkg](https://github.com/autopkg/autopkg), release 2.2 or greater is required as earlier versions do not have Munki repo plugin support. Please note that release 2.2 includes a bug that prevents _updates_ from uploading. Please use AutoPkg 2.3, or as this version has not yet been released as of today (9/9/2020), build and install AutoPkg from the source available in the master branch. 
 
 ## Installation
 
-1. Place `SimpleMDMRepo.py` in the `/usr/local/munki/munkilib/munkirepo/` folder.
-1. (Optionally) move `config.plist` to `/usr/local/simplemdm/munki-plugin/config.plist`.
+Download and install the [latest release](https://github.com/SimpleMDM/munki-plugin/releases/latest).
