Update docs to fork this repo

[iancrowther]

This repo should be forked to accomodate multiple developers

[PatrickHeneise]

There shouldn't be any issues here in this repo, as it's just a playground. For replication https://github.com/GiteventsPlayground should be used (depending on 1-3 repo setup)

"https://github.com/GiteventsPlayground" - is this a typo?

[iancrowther]

also this should be forked so we can all work concurrently. the webhook only accomodates single urls

[PatrickHeneise]

@iancrowther where's the typo?

[iancrowther]

your right, ignore me on that point!
