+### 🚀 Add caching for faster CI
 
-You can have this action configure the substitutes for you. This will allow you to push build artifacts to a remote Nix store, and have subsequent builds substitute paths using that same store.
+Caching with flox can be achieved by configuring what is known as
+`substituter`.
 
-See [nix help-stores] for more information on the supported URIs.
+You can see in an example below how to configure your GitHub workflow to **push
+build artifacts** to a remote location. In the case of this example it is an
+AWS S3 Bucket.

+With caching configured all subsequent builds will be faster since flox does
+not have to build them again.
 
-The following example configures a S3 substituter, builds a package, and pushes the artifact to the substituter. Subsequent runs of this workflow will use the substituted path, instead of building it again.
+See [nix help-stores][nix-help-stores] for more information on the supported
