# Contributing

First off, thank you for considering contributing to Mapbox Maps for Flutter! It's people like you that make this project such a great experience.

If you have a usage question about the Mapbox Maps SDK for Flutter, please visit https://www.mapbox.com/help/.

If you'd like to contribute code:

1. Please familiarize yourself with the [install process](https://pub.dev/packages/mapbox_maps_flutter/install), the [development process](DEVELOPING.md), and the contributor license agreement (CLA) at the bottom of this document. All contributions to the project must reflect its development standards and be offered under the terms of the CLA.

2. Ensure that existing [pull requests](https://github.com/mapbox/mapbox-maps-flutter/pulls) and [issues](https://github.com/mapbox/mapbox-maps-flutter/issues) don’t already cover your contribution or question. If your planned contribution involves significant changes to the SDK, consider opening a new issue to discuss your design before beginning work.

3. Pull requests are gladly accepted. If your PR makes changes to the SDK that developers should be aware of, please be sure to update [CHANGELOG.md](CHANGELOG.md)

4. Prefix your commit messages with the relavent labels that your changes affect: `[sdk]`, `[gestures]`, `[animation]`, `[location]`, ...

### GitHub issue labels

Our labeling system is:

 * **minimalistic:** Labels’ usefulness are inversely proportional to how many we have.
 * **objective:** Labels should be objective enough that any two people would agree on a labeling decision.
 * **useful:** Labels should track state or capture semantic meaning that would otherwise be hard to search for.
