Sigh.
I created this page in 2012 when MediaWiki was transitioning from SVN to Git. Back then, a lot of people, including myself, were not familiar with Git, and even fewer people were familiar with Gerrit. The page "Gerrit/Workflow" was written, but people complained that it's too long, because it was about 20 pages in print (since then it was quite appropriately renamed to Gerrit/Advanced usage). So somebody wrote Gerrit/Tutorial, with the purpose of being a simpler page. Unfortunately, that page also quickly grew to about 20 pages in print.
So I created this page with the intention of being a very short Git manual, which would give the most basic and frequently-needed commands, and link to other pages for more advanced or rarely needed info. In the invisible HTML comment at the top I wrote that it must remain under one page in print. To match this purpose, I called it "Git/TLDR".
I don't know why was it renamed to "Gerrit/Getting started".
I'm biased, of course, but I support moving it back to "Git/TLDR".
