# esp32-arduino build instructions

We build our own custom version of esp32-arduino, in order to get some fixes we've made but haven't yet been merged in master.

These are a set of currently unformatted notes on how to build and install them. Most developers should not care about this, because
you'll automatically get our fixed libraries.
