Creating pull requests against core: the easy (noob) way
I do not consider myself a coder. My contributions in the issue queues both in drupal.org as well as in the GitHub repository of Backdrop CMS had very little to do with actual code. That was until a few months ago Geoff (@serundeputy) showed me a way to create PRs though the GitHub UI that I find very easy (although not very coder-like).
