I can create the meta info if you give the go ahead to add this hook

@dan-klasson Your file is incomplete. First of all you should place meta info on the top of the file look into other MD files and take reference from there. Also you should place 2-3 line description what your hook does and how it's useful and last it would be great if you add Typescript version of that code to the same file. Take a look into already created MD files, it will help you to structure everything well.

@nickvdyck Yeah, like I said. Willing to add all that if the hook is going to get accepted.
