 These are the daily builds for the FNA native libraries.
 
-You probably want the [Actions tab](https://github.com/FNA-XNA/fnalibs-dailies/actions).
+This repository automatically creates archives containing all of the native libs that can be used by FNA. For more information about these libs, visit the [FNA documentation](https://fna-xna.github.io/docs/1%3A-Setting-Up-FNA/#step-2-download-native-libraries). 
+
+Note that this archive always targets the latest development version of FNA - compatibility with stable releases is not guaranteed. 
+
+To download the latest fnalibs, go to the [Actions tab](https://github.com/FNA-XNA/fnalibs-dailies/actions) and select the latest "CI" build. At the bottom of the page will be two "artifacts", named fnalibs and fnalibs-apple. Those links are the zip files you want!
