(I had to publish the page to unblock publishing of changes on Portal:Toolforge but I will still apply any copyedits you suggest to the final revision!)

Awesome work! The what is Toolforge and what are tools and bots sections are perfection! I made a few minor edits to page directly.

• "mosh, SSH, SFTP" – It would be good to link to a Wikipedia article for each of these since they are likely to be unfamiliar terms.
• "Version control via Gerrit and Git" – I recommend removing Gerrit. The page this line links to includes multiple options (GitLab, etc.), so I don't think it's necessary to call out Gerrit, and it makes for one less unfamiliar term in the list.
• I love the constraints section! I expected to see something here about licensing your code under an open source license, but that is technically covered under the Cloud Services terms of use. Up to you!
