# Getting Oriented (https://jackin.tailrocks.com/reference/getting-oriented/)



Two pages to read before diving in:

* **[Architecture](/reference/getting-oriented/architecture)** — design constraints, image layers, container lifecycle, networking, and how the host and container halves fit together.
* **[Codebase Map](/reference/getting-oriented/codebase-map)** — where to find things in the repository, contributor entry points, and a code ↔ docs cross-reference.
