Preliminaries

First, find your partner. Click on the assignment link. One partner should create a new team. The team name cannot be the same name used for a previous lab. The second partner should click the link and choose the appropriate team. (Please don’t choose the wrong team, there’s a maximum of two people and if you join the wrong one, you’ll prevent the correct person from joining.) The team name can be the same as what you used in previous labs.

Once you have accepted the assignment and created/joined a team, you can clone the repository and begin working.
