Cleanup and re-arrange information

I've started this work cleaning up the ToC in #44 however after doing so I noticed there's further work to be done to remove duplicates (github personal access tokens, for example), and provide document references on further items. I'm happy to tackle this soon but raising this with help wanted in case somebody else would like to take it on.

Hey I would lobe to help. I would like to create an PR template and a more organised structure to the display of the information.
