- On your host machine, clone repositories into `./workspace` and make changes as usual.

+To install extra packages into your container, add the ubuntu package names to `./extra_packages.txt`, one per line. They will be installed the next time you start a new shell. To keep git from tracking your changes to this file, run `git update-index --skip-worktree ./extra_packages.txt`.

+### Adding libraries to the toolchain sysroot
Put files that you want included in the sysroot (libs and headers, you've built, etc.) in `./extras`. They will be copied to `$SYSROOT/usr` as the container is built.
