Creating extensions

I have just started developing my first Auth0 Extension. And I have to say, it hasn’t been a good experience up until now. Apart from the ‘documentation’ you get with the command-line steps, there’s 0 documentation that I could find. Also, even those steps are not 100% correct (for example, they assume you only have one webtask profile, even though specifying the profile name for wt createwould be just as easy…)

The Auth0 github org contains a few boilerplates, for example for react, but they are different from the code wt-gallery creates when scaffolding.
The Auth0 github org also contains a few assorted tools, like for redux, react ui components, express helpers, but it’s quite a challenge to put all the pieces together.

Is there anything comprehensive around Extension development that I can refer to?
