Question: Please help me understand how to correctly include an extension?

[redevill]

I have the backgrid working, and have made some enhancements. While I am able to follow the extension pattern presented, I am missing a simple piece: Where is the extension project placed / included / linked such that the npm install will do as the documentation suggests?

"# Recursively builds the core, extensions and put the output into lib"

There is much on the how to use each extension, but nothing I can find on how to include an extension into the distribution. From what I can make out, the Extension code should wind up in the Extension: {} definition in the backgrid output lib code. Again, how do I achieve this? I am happy to read / learn docs if someone can point me in the right direction.

Perhaps I am just missing the correct "npm install myExtension --save" invocation?

Thanks
