+Created based on the rp-pico BSP.
+
+### Added
+
+- None
+
+### Changed
+
+- Pin assignments to match Pico W hardware.
+
+### TODO
+
+- Implement Wifi driver
+- Add led pin (not a native GPIO, but could provide a compatible
+  API so rp-pico examples can work on rp-pico-w with little modification)
+- Fix pico_w_blinky example.

+# [rp-pico-w] - Board Support for the [Raspberry Pi Pico] W
+
+You should include this crate if you are writing code that you want to run on
+a [Raspberry Pi Pico] W - the Wifi enabled version of the [Raspberry Pi Pico].
+
+This crate includes the [rp2040-hal], but also configures each pin of the
+RP2040 chip according to how it is connected up on the Pico W.
+
+**NOTE**: This is work in progress. Wifi access is not yet implemented.

+[rp-pico-w]: https://github.com/rp-rs/rp-hal/tree/main/boards/rp-pico-w
+[rp2040-hal]: https://github.com/rp-rs/rp-hal/tree/main/rp2040-hal
+[Raspberry Silicon RP2040]: https://www.raspberrypi.org/products/rp2040/
+
+## Using
+
+To use this crate, your `Cargo.toml` file should contain:
+
+```toml
+rp-pico-w = "0.0.1"
+```
+
+In your program, you will need to call `rp_pico_w::Pins::new` to create
+a new `Pins` structure. This will set up all the GPIOs for any on-board
+devices. See the [examples](./examples) folder for more details.
+
+## Examples
+
+### General Instructions
+
+To compile an example, clone the _rp-hal_ repository and run:
+
+```console
+rp-hal/boards/rp-pico-w $ cargo build --release --example <name>
+```
+
+You will get an ELF file called
+`./target/thumbv6m-none-eabi/release/examples/<name>`, where the `target`
+folder is located at the top of the _rp-hal_ repository checkout. Normally
+you would also need to specify `--target=thumbv6m-none-eabi` but when
+building examples from this git repository, that is set as the default.
+
+If you want to convert the ELF file to a UF2 and automatically copy it to the
+USB drive exported by the RP2040 bootloader, simply boot your board into
+bootloader mode and run:
+
+```console
+rp-hal/boards/rp-pico-w $ cargo run --release --example <name>
+```
+
+If you get an error about not being able to find `elf2uf2-rs`, try:
+
+```console
+$ cargo install elf2uf2-rs
+```
+then try repeating the `cargo run` command above.
+
+### [pico_w_blinky](./examples/pico_w_blinky.rs)
+
+Flashes the Pico W's on-board LED on and off.
+
