+# Raspberry Pi Pico 2 - with Rust!
+
+You will need nix with flakes enabled. Then:
+
+```shell_session
+$ direnv allow # setup rustup and picotool
+$ rustup show # install rustc, cargo, and the pico 2 toolchain
+# plug in your pico 2 while holding the BOOTSEL button
+$ cargo run --release
+# this will probably fail the first and you will need to install whatever is missing with rustup
+# then try again
+```
+
+Have fun!
