 - `gpiote`: GPIOTE driver. Allows `await`ing GPIO pin changes. Great for reading buttons or receiving interrupts from external chips.
 - `rtc`: RTC driver implementing `Clock` and `Alarm`, for use with `embassy::executor`.
 
-## Running the examples
+## Examples
 
-Examples are for the nRF52840 chip but should be easily adaptable to other nRF52 chips.
+Examples are found in the `examples/` folder seperated by the chip manufacturer they are designed to run on:
+*   `examples/nrf` are designed to run on the `nrf52840-dk` board (PCA10056) but should be easily adaptable to other nRF52 chips and boards.
+*   `examples/rp` are for the RP2040 chip.
+*   `examples/stm32` are designed for the STM32F429ZI chip but should be easily adaptable to other STM32F4xx chips.
+*   `examples/std` are designed to run locally on your pc.
 
-GPIO pins are set up for the `nrf52840-dk` board (PCA10056)
+### Running examples

+- Setup git submodules (needed for STM32 examples)
+```
+git submodule init
+git submodule update
+```
 
 - Install `probe-run` with defmt support.
