Docker tutorial TODOs:

• Sharing an app
• Bind mounts (kinda finicky with Vagrant due to Windows symlink permissions, but might be solvable) and latter parts of Multi container apps due to other issues with yarn, which I won't look into because I don't care about all this Node stuff.
• Same thing for Use Docker compose
