Add Github searching info and filter usage in this repo?

[iteles]

One of the things I have found most useful as someone who liaises with clients is being able to tell how to use Github's filter box to tailor the issue backlog to what is most relevant to them.

Examples:

• Remove the technical label from issues they see
• Filter by sprint milestone
• Filter by issues assigned to them
• Filter by specific labels, e.g. question

Should we include this in this repo? Or is it too much for the beginner?

This would be super useful to people who need to find stuff... won't harm beginners if its far down in the "page"...
