+
+These are notes to myself mainly. 
+1. Start by following [the main guide](https://docs.micropython.org/en/latest/develop/gettingstarted.html).
+
+2. For Mac you can get the build chain through a [special brew tap](https://github.com/ARMmbed/homebrew-formulae:
+
+```sh
+brew tap ArmMbed/homebrew-formulae
+brew install arm-none-eabi-gcc
+```
+
+You also need the brew equivalents of the dependencies listed:
+`brew install gcc cmake libffi-dev git pkg-config`
+
+3. Build `mpy-cross` as directed.
+
+4. Build the unix port just because it's useful
+
+5. Build the port for the board you want, RP2040 for me
+```
+cd ports/rp2 
+make submodules
+make -j 16
+```
+
+6. Build the port with additional libraries.
+I wanted to try out this [display driver](https://github.com/russhughes/gc9a01_mpy) so following the build instructions there, I ran:
+```
+make USER_C_MODULES=../../../gc9a01_mpy/src/micropython.cmake all
+```
+
+If you run into trouble, it helps to `make clean` in between trying things. I upgraded my `cmake` and it didn't seem to help until I ran make clean and tried again.
