This is a very basic overview of setting up a git repo and then working with it from 2 stations. This will be reviewed in class if I can make it work this time!

Initialize the a central repo on a host (the lab machines?)

buzbee@shell:~> git init --bare repo.git
Initialized empty Git repository in /home/grads/buzbee/repo.git/

(Recommended, but not shown) Setup groups so that each user has a different account

Clone the repo on one workstation

root@benbuzbee:~# git clone buzbee@shell.cs.fsu.edu:/home/grads/buzbee/repo.git
Cloning into repo...
The authenticity of host 'shell.cs.fsu.edu (128.186.122.11)' can't be established.
RSA key fingerprint is 63:60:9e:bf:ac:b6:51:2e:b5:6f:7a:6b:7f:24:83:df.
Are you sure you want to continue connecting (yes/no)? yes

Add your first file
