+# Getting Started
+
+[`selfdrive`] is a rather *complicated* repo.
+
+If you've never worked on a project of this scale, it can be daunting to
+know where to start. The goal of this guide is to give you enough of a
+foothold to start asking the right questions and to begin your adventure
+here at Autonomy Lab.
+
+## Fundamentals
+
+Before we even get to cloning [`selfdrive`], you need to have the basic
+mechanical skills required to traverse a shell. [MIT's Missing Semester]
+serves as a great starting point for just this. The following table
+lists the lectures you should watch if you plan to work on a specific
+Autonomy Lab group:
+
+| Lecture                       | Hardware | Firmware | Algorithms |
+| ----------------------------- | -------- | -------- | ---------- |
+| [Course overview + the shell] | ✓\*      | ✓\*      | ✓\*        |
+| [Shell Tools and Scripting]   | ✓        | ✓\*      | ✓\*        |
+| [Editors (Vim)]               |          |          |            |
+| [Data Wrangling]              |          | ✓        | ✓\*        |
+| [Command-line Environment]    | ✓        | ✓\*      | ✓\*        |
+| [Version Control (Git)]       | ✓\*      | ✓\*      | ✓\*        |
+| [Debugging and Profiling]     |          | ✓        | ✓          |
+| [Metaprogramming]             |          | ✓        | ✓          |
+| [Security and Cryptography]   |          |          |            |
+| [Potpourri]                   |          | ✓        | ✓          |
+| [Q&A]                         |          | ✓        | ✓          |
+
+> *Note: an `*` denotes you should also do the associated exercises.*
+
+At a minimum, to clone [`selfdrive`], you should watch and do the
+exercises for [Course overview + the shell] and [Version Control (Git)],
+as these lectures provide you the fundamentals to hit the ground
+running.
+
+## System Configuration
+
+Since [`selfdrive`] consists of software written in different
+programming languages with a wide variety of dependencies, we've made an
+effort to make getting your machine ready as painless as possible with
+the [Nix package manager] and [direnv]. You can find cloning
+instructions and system setup information on the repo's [`README.md`].
+
+## Repo Layout
+
+> Currently, [`selfdrive`] does not respect this structure. We're in the
+> process of migrating over to this layout. Sorry for the time being.
+
+```
+selfdrive/
++-- docs/
+|
++-- components/
+|   +-- component/
+|   |   +-- docs/
+|   |   +-- src/
+|   |   +-- component.yml
+|   |
+|   +-- ...
+|
++-- lib/
+|
++-- projects/
+|   +-- project/
+|   |   +-- docs/
+|   |   +-- project.yml
+|   |
+|   +-- ...
+|
++-- can.yml
+|
++-- ...
+```
+
+There's quite a bit to unpack here, so let's get to it!
+
+### [`components/`]
+
+The [`components/`] directory contains components that serve as the
+building blocks of a project.
+
+Each component has a `docs/` directory that contains [symlinks] to
+relevant documentation. These symlinks need to stay up to date as they
+will automatically get triggered for manual review on pull requests to
+ensure that documentation stays up to date. Having these symlinks also
+ensures that anyone who wishes to get up to speed on a component has a
+quick list of relevant documentation to read.
+
+The `src` directory contains the source files. The contents and layout
+of this directory highly depend on the component language(s) and use
+case. It is best to see existing components to get a feel for it.
+
+Finally, `component.yml` contains metadata related to the component.
+
+### [`docs/`]
+
+The [contributing guidelines] cover the structure for documentation. You
+may notice that it closely follows the structure of [`selfdrive`]
+itself.
+
+### [`lib/`]
+
+The [`lib/`] directory contains shared libraries used in components.
+Since these are generalized pieces of software, the contents of each
+directory can wildly vary. Feel free to explore these directories if
+you're curious.
+
+### [`projects/`]
+
+The [`projects/`] directory contains projects that are composed of
+various components. Like a component, each project has a `docs/`
+directory with symlinks to relevant documentation and a `project.yml`
+with related metadata.
+
+### [`can.yml`]
+
+[`can.yml`] describes the CAN networks of our projects. Here, you'll
+find definitions for networks, messages, and signals for [OpenCAN] to
+process.
+
+### What About Everything Else?
+
+It'd be impractical to cover every last file and directory in
+[`selfdrive`]. Unfortunately, there's no shortcut to knowing where you
+can find everything or how various bits of code interact, but there are
+tools that can help!
+
+- [`fd`]: a simple, fast and user-friendly alternative to `find`
+- [`fzf`]: a command-line fuzzy finder
+- [`rg`]: ripgrep recursively searches directories for a regex pattern
+
+## So What's Next?
+
+Now that you have a general idea of how [`selfdrive`] works, it's time
+to move on to group-specific getting started guides. Feel free to move
+along to these without finishing all of the suggested [missing semester]
+lectures; however, understand they do nothing but benefit you!
