 ## how to use
 
 ### enabling the 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!
+all packages are cached in my own [attic](https://github.com/zhaofengli/attic) instance. you can use this
+yourself by following the instructions [here](https://docs.attic.rs/user-guide/index.html), with the endpoint
+being `https://cache.mydadleft.me` and no token required. the binary cache endpoint `https://cache.mydadleft.me/nix-exprs`
+may also be used in the `nixConfig` attribute of flakes or a system configuration.
