tortoisegit does not pull

I am new to Git. I installed msysgit, configured ssh and pulled a solution from GitHub (my own solution, I pushed it from a different computer). The pull worked.

Now, I installed tortoisegit to make life easier. It displays the correct items in Windows Explor开发者_运维技巧er. I would expect a "pull" and push entries in the context menus, but I can't find them. Where's by mistake?

This tutorial on using TortoiseGit with GitHub mentions:

TortoiseGit’s Sync dialog is basically one dialog with both pull and push in it.
Pretty easy if you need to do either or both.

Pushing your changes to your repository:
1/ TortoiseGit→Sync
- 1/ (Local and remote branches should be merge at this point, Remote URL should be origin)
- 2/ Push

Pulling any changes from your repository:
1/ TortoiseGit→Sync
- 1/ (Local and remote branches should be merge at this point, Remote URL should be origin)
- 2/ Pull
