Documentation Problem - Rebase needs more info and accurate info for setting upstream from CLI

What steps will reproduce the problem?

1. Navigate to this link: https://tortoisegit.org/docs/tortoisegit/tgit-automation.html
2. Scroll to the :rebase command.

Snipped from your webpage.

What is the expected output? What do you see instead? I expect to see accurate information, clear information: for example, you have /uptream as a command. Is that accurate or should it be /upstream?

Also, what is the correct usage of the command? /uptream:rev:master or /uptream:rev:"master" or /uptream:rev:remotes/origin/master or /uptream:"remotes/origin/master"

I tried all of those and none of them work.

What version of TortoiseGit and Git are you using? On what operating system? 2.13.0.0 and previous versions (none of them work) Windows 10 Professional x64

Please provide any additional information below. If this feature does work can you provide me accurate information on how to use this command, I need it. I need to know how to set the onto branch to a local branch or a remote branch. Does the branch need to be fetched before it can be switched too or will TortiseGit just look for it on GitLab?
