I've refactored the Magit Forge page into separate pages for creating, viewing and updating issues, pull requests and forks. This should make it easier to find the relevant guides. I've also added some screenshots. I really like being able to do the whole pull request from within Emacs, expecially a projects pull request template is used when you create that pull request, which I find far quicker to edit in Emacs than GitHubs website https://practical.li/spacemacs/source-control/magit/forge/
