Feedback:

This page has a link to these instructions that goes to some GH gist for aws-amplify-ops, which only has this 1 gist. Recommend moving these instructions to the actual docs instead somewhere for JS/RN.

For the other platforms, it points to the same gist which does not apply for flutter, swift, android
