[Docs]: Add docs, readmes and reference docs for repo watchers

[rtshkmr]

We have the luxury of having a group of users that shall help us iterate on the UX and feature-set that we wanna support.

This means that we should have some basic quality of first-touchpoint for repo-watchers.

Some things to support:

1. README should have elixir redirects for people who don't know
2. running FAQ section
3. our own tree of links:
   • blog
   • deployed site
4. dispatch a blog post to summarise the watcher view
   • use some of the buildspace copy for this
5. broad roadmap / next milestone point
