 XCRemoteCache supports building artifacts for Apple silicon consumers. Is it recommended to build separately for `x86_64` and `arm64` architectures to have single-architecture artifacts that do not require downloading irrelevant binaries. Here are required steps if you want to support both Intel and Apple silicon consumers.
 
-* Add `ARCHS` to `custom_fingerprint_envs` in your `.rcinfo`, e.g.
-```
-custom_fingerprint_envs: 
-  - ARCHS
-```
 * Building for a simulator on a producer: run a first build for `x86_64`, clean a build and build again for `arm64`, e.g.:
 ```
 xcodebuild ARCHS=x86_64 ONLY_ACTIVE_ARCH=NO build ...
