Making Changes

1. The openpilot install is housed in /data/openpilot. The code can be modified in place, reboot after changes to see new changes.
2. The official release branch is release3 for the comma3 and release2 for the comma2, which comes with precompiled binaries, but most branches do not have binaries. Other interesting branches include master (latest), master-ci (latest + submodules), devel, and devel-staging
3. Binaries are compiled at boot time assuming they aren't already supplied by the branch (device will take 20+ minutes to boot). To monitor the build, ssh in and attach to the tmux session via tmux a
4. Keep in mind that at the time of writing /cereal, /laika_repo, /opendbc, /panda, /rednose_repo, /laika, and /rednose are all submodules. If you wipe /data/openpilot and clone fresh be sure to issue the command git submodule update --init --recursive after cloning for a successful build.
