 If the assignments repo has changed, either due to assignments being changed or bugs found (found at `os161-container/assignments`) you will need to just run `sudo ./install.sh` again.

+## Common Issues
+
+**Commands do not work and also there is randomly ^M, strings within the output:**
+This is due to windows placing return characters in the strings that get
+passed to the scripts. Please use git bash or a terminal that does UNIX
+string passing.
+
+**Cannot figure out the host**
+This occurs within newer level Macs that use Apple Silicon, docker
+currently requires x86 architectures to work, you'll need to use the
+student environment.
