This package contains the "core" of Kaleidoscope and a number of [example firmware "Sketches"](https://github.com/keyboardio/Kaleidoscope/tree/master/examples).
If you're just getting started with the Keyboardio Model 01, the [introductory docs are here](https://github.com/keyboardio/Kaleidoscope/wiki/Keyboardio-Model-01-Introduction) and the source for the basic firmware package is here: https://github.com/keyboardio/Model01-Firmware. It's probably a good idea to start there, learn how to modify your keymap and maybe turn some modules on or off, and then come back to the full repository when you have more complex changes in mind.
If you want to use Kaleidoscope to customize or compile a "sketch" to power a supported keyboard, the fastest way to get started is to use the Arduino IDE. You can find [setup instructions](https://kaleidoscope.readthedocs.io/en/latest/quick_start.html) on [kaleidoscope.readthedocs.io](https://kaleidoscope.readthedocs.io)
For the purposes of this tutorial, we'll assume your checkout is in a directory called `kaleidoscope` inside a directory called `git` in your home directory.
