Apologies for not fixing this up sooner. I will make the requested changes tonight after work.

@AUSBird that's okay! Please update the way you list claims, cut down on the number of scopes in the config snippet and use a plain link in the snippet instead of a hyperlink and we should be good to merge.

@tomekpapiernik I have made the changes. I swapped the claim list into a list that doesn't add long descriptions to each claim (That said they are kind of obvious what they do) two claims have a slash cause they are the same. And I removed all but two scopes in the config example with a link to the docs with the rest of the scopes.

Thanks for your contribution! 🎉 I've applied minor cosmetic tweaks myself to speed things up. Merging once all tests pass. Cheers!
