Editing on GitHub
Edits can be made to the site's code directly from the GitHub repository, if you are listed as a contributor for the repo. Just find the file you'd like to edit (the filename will be the same as the page's slug -- "edit-docs" for this page) and click the pencil icon in the corner. Once you've completed your changes, scroll to the bottom, add a commit message, and click "Commit changes". The public docs will update to reflect this.
