torlauncher has no readme file

https://gitweb.torproject.org/tor-launcher.git/tree/ doesn't give me any place to start in terms of building or using the extension.

It would probably be helpful to teach people at least these few things:

• Tor launcher is intended only for use in Tor Browser, not for putting in your own Firefox. (But also it's supported for use in Tor Messenger, and maybe others?)

• Here's what you need to do to make your own xpi, e.g. if you've changed the translations and you want to rebuild it for testing.

• Some pointer to the Tor Browser build docs, so people can learn where Tor Launcher fits into the bigger picture.

And maybe more?
