## Contributing to Drivers

If you want to write drivers for Redox, datasheets are preferable, when they are freely available. Be aware that datasheets are often provided under a [Non-Disclosure Agreement](https://en.wikipedia.org/wiki/Non-disclosure_agreement) from hardware vendors, which can affect the ability to create an MIT-licensed driver.

If you don't have datasheets, we recommend you to do reverse-engineering of available C code of BSD drivers.

We recommend BSDs drivers because BSD license is compatible with MIT (permissive), that way we can reuse the code in other drivers.
