Need some document/instruction for watch apps and app extensions

Hi guys, I am trying to create watch app with corodva app. Is there any place I could have a document/instruction on how to add watch2 apps and app extensions with cordova-node-xcode? I am sorry but don't know where is the correct place to ask this question. I greatly appreciate any help.

The issue names no source file or test. Start by reviewing the repository's existing documentation and determining how cordova-node-xcode handles Watch 2 apps and app extensions; done means clear, validated instructions are added for creating them.
