This should be higher priority. How do I use this field in my templates for example? There are no docs on this it seems.

Since this is an optional module dev docs should remain be in README.md, not doc.silverstripe.org

Regarding "All docs in the repo is moved to the official developer docs and removed from the repo.", I had a discussion on slack with Max about this.
Instead we will be moving the docs into the docs/en/ directory in the module, and having the developer docs site pull content from there (like userhelp pulls a bunch of its docs from other modules).

Assigning back to Guy to confirm that everything deployed correctly

Docs site didn't break so that's a good sign lol.
We won't be able to check fully until we add a 4.0 branch fo linkfield and get the docs site to pull from 5.2 in developer docs.
