 ## Configure SSH keys
 
 The GitLab of ULiège does not allow you to use your student-ID / password for git commands. It uses a pair of "SSH keys" (one "private key" that should never be shared with anyone and a "public key" which can be given to anyone who wants to check that you own the "private key").

 I have created a powerpoint presentation for teaching git to my colleagues/students. You may download the current (unfinished) version with the link below:

 Unlike the links above, this presentation focuses on the tools used at the University of Liège (this GitLab) and on the Windows operating system (because most of my colleagues/students use Windows). I also start the presentation by the local usage of git before using GitLab, so that branches and cleaning operations are well understood before going online. The git features of Visual Studio Code are also presented.
