Who is this aimed at?

I always got the impression this repo was aimed at open source contributions for a developer coming into an unfamiliar project, but after a discussion with @nelsonic I wasn't sure. Having read through the first half it still feels like it.

From my experience (small team) the creating an issue & validating an issue is not a big part of the process as the PO will have created most issues (therefore don't need to be validated), it is only a few specific types of technical issue that I feel need to be validated.
