 ## how to use
 
 ### enable binary cache
 
-all packages are built with [garnix](https://garnix.io/), and cached on their servers. you can use this
-yourself by following the instructions [here](https://garnix.io/docs/caching). i would also recommend
-[donating](https://opencollective.com/garnix_io) if you can!
+linux packages are built with [hercules-ci](https://hercules-ci.com/), while packages for apple silicon 
+are built with [garnix](https://garnix.io/). both have binary caches, however different ones; you can use
+garnix's by following the instructions [here](https://garnix.io/docs/caching), and the cachix cache for
+hercules-ci by following the instructions [here](https://app.cachix.org/cache/getchoo#pull). i would also recommend
+[donating](https://opencollective.com/garnix_io) to garnix if you can!
