## Ways to contribute
As CircuitPython grows, there are more and more ways to contribute. Here are some ideas:

* Build a project with CircuitPython and share how to do it online.
* Test the latest libraries and CircuitPython versions with your projects and file issues for any bugs you find.
* Contribute Python code to CircuitPython libraries that support new devices or features of an existing device.
* Contribute C code to CircuitPython which fixes an open issue or adds a new feature.

## Getting started with C
CircuitPython developer Dan Halbert (@dhalbert) has written up build instructions using native build
tools [here](https://learn.adafruit.com/building-circuitpython).

## Code guidelines
We aim to keep our code and commit style compatible with MicroPython upstream.
Please review their
[code conventions](https://github.com/micropython/micropython/blob/master/CODECONVENTIONS.md) to do so.
Familiarity with their [design philosophy](https://github.com/micropython/micropython/wiki/ContributorGuidelines)
is also useful though not always applicable to CircuitPython.

Furthermore, CircuitPython has a
[design guide](https://circuitpython.readthedocs.io/en/latest/docs/design_guide.html)
that covers a variety of different topics. Please read it as well.
