A website, API and CLI. Each are different projects with different dependencies and requirements. They are in the same repo for the sake of convenience.

Both the CLI and server are currently in alpha status. This means that neither are feature complete nor stable enough to rely on for real-world usage.

They each will be bumped to beta status when all core features are implemented. At that point they would be stable enough to use in a non-mission-critical setting.

While in alpha, the best place to start is likely the contributing guide.
