# How to contribute
|
|
|
|
Our software is open source so you can solve your own problems without needing help from others. And if you solve a problem and are so kind, you can upstream it for the rest of the world to use. Check out our [post about externalization](https://blog.comma.ai/a-2020-theme-externalization/). Development activity is coordinated through our GitHub Issues, [GitHub Discussions](https://github.com/commaai/openpilot/discussions), and [Discord](https://discord.comma.ai).
|
|
|
|
### Getting Started
|
|
|
|
* Setup your [development environment](../tools/)
|
|
* Read about the [development workflow](WORKFLOW.md)
|
|
* Join our [Discord](https://discord.comma.ai)
|
|
* Docs are at https://docs.comma.ai and https://blog.comma.ai
|
|
|
|
### What contributions are we looking for?
|
|
|
|
**openpilot's priorities are [safety](SAFETY.md), stability, quality, and features, in that order.** openpilot is part of comma's mission to *solve self-driving cars while delivering shippable intermediaries*, and all developoment is towards that goal.
|
|
|
|
The probability of a pull request being merged is a function of its value to the project and the effort it will take us to get it merged.
|
|
If a PR offers *some* value but will take lots of time to get merged, it will be closed.
|
|
Simple, well-tested bug fixes are the easiest to merge, and new features are the hardest to get merged.
|
|
|
|
All of these are examples of good PRs:
|
|
* typo fix: https://github.com/commaai/openpilot/pull/30678
|
|
* removing unused code: https://github.com/commaai/openpilot/pull/30573
|
|
* simple car model port: https://github.com/commaai/openpilot/pull/30245
|
|
* car brand port: https://github.com/commaai/openpilot/pull/23331
|
|
|
|
### What doesn't get merged?
|
|
|
|
* arbitrary style changes
|
|
* PRs without a clear goal
|
|
* 500+ line PRs: it should be either cleaned up, broken up into smaller PRs, or both
|
|
|
|
### First contribution
|
|
|
|
Check out any [good first issue](https://github.com/commaai/openpilot/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) to get started.
|
|
|
|
### What do I need to contribute?
|
|
|
|
A lot of openpilot work requires only a PC, and some requires a comma device.
|
|
Most car-related contributions require access to that car, plus a comma device installed in the car.
|
|
|
|
## Pull Requests
|
|
|
|
Pull requests should be against the master branch. If you're unsure about a contribution, feel free to open a discussion, issue, or draft PR to discuss the problem you're trying to solve.
|
|
|
|
A good pull request has all of the following:
|
|
* a clearly stated purpose
|
|
* every line changed directly contributes to the stated purpose
|
|
* verification, i.e. how did you test your PR?
|
|
* justification
|
|
* if you've optimized something, post benchmarks to prove it's better
|
|
* if you've improved your car's tuning, post before and after plots
|
|
* passes the CI tests
|
|
|
|
### Car Ports
|
|
|
|
We've released a [Model Port guide](https://blog.comma.ai/openpilot-port-guide-for-toyota-models/) for porting to Toyota/Lexus models.
|
|
|
|
If you port openpilot to a substantially new car brand, see this more generic [Brand Port guide](https://blog.comma.ai/how-to-write-a-car-port-for-openpilot/).
