 ### Building fnalibs
 
-The process of building all the fnalibs is normally very tedious, and everybody _loves_ how good Xcode is, so as an alternative to building each project by hand, we have a pair of [build scripts](https://github.com/TheSpydog/fnalibs-ios-builder) that automatically download and build all of the fnalibs at once. If you would like to see the process in detail, take a look at the script sources - they're human-readable!
+macOS, iOS, and tvOS libraries are now built automatically and can be downloaded from [fnalibs-dailies(https://github.com/FNA-XNA/fnalibs-dailies/actions)].  You may need to be logged into github to download these.  Simulator libraries are not currently provided, so you will need to build those yourself if desired.
