+With this knowledge, you'll be well equipped to start making your own games!
+
+## Getting started
+
+To start, create a new repository based on the [agb template](https://github.com/agbrs/template).
+We'll call this `pong`.
+
+Then replace the `name` field in `Cargo.toml` with `pong`, to end up with something similar to:
+
+```toml
+[package]
+name = "pong"
+version = "0.1.0"
+authors = ["Your name here"]
+edition = "2018"
+
+# ...
+```
+
+You are now ready to get started learning about how `agb` works.
