+## Flashing & IDE Integration
+
+This project is configured for seamless flashing from the IDE or terminal.
+
+### Flashing from IDE
+
+If you are using **RustRover** or **IntelliJ Rust**, you can use the "Flash Pico W" run configuration provided in the `.run` folder. Just select it from the run menu and click "Run".
+
+### Flashing from Terminal
+
+You can flash the Pico W by running:
+
+```bash
+cargo run --release
+```
+
+This uses `probe-rs` (configured in `.cargo/config.toml`) to flash and run the binary via a CMSIS-DAP debugger or similar.
+
+If you prefer to use the UF2 bootloader (dragging to the drive or using `elf2uf2-rs`), you can change the runner in `.cargo/config.toml` to:
+`runner = "elf2uf2-rs -d"`
+
