 # Raspberry Pi Pico 2 - with Rust!
 
-You will need nix with flakes enabled. Then:
+# Setup
 
-```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
-```
+1. Get `rustup` and `picotool` by running `direnv allow` (or however you like)
+2. Install Rust components via `rustup` by running `rustup show`
 
-Have fun!
+# Flashing
+
+Hold your Pi Pico 2's `BOOTSEL` button while plugging it in to your machine.
+Then run `cargo run --release`.
+
+To use the RISC-V target, run
+`cargo run --release --target riscv32imac-unknown-none-elf`.
