## Changing code and contributing
This [Developer Guide](https://docs.px4.io/master/en/development/development.html) is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.

### Weekly Dev Call
The PX4 Dev Team syncs up on a [weekly dev call](https://dev.px4.io/master/en/contribute/#dev_call).
The PX4 Dev Team syncs up on a [weekly dev call](https://docs.px4.io/main/en/contribute/).
> **Note** The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the [Dronecode calendar](https://www.dronecode.org/calendar/).
