We have a lot of development work to do:

• Open Food Facts backend (Perl and MongoDB);
• Web site (HTML5, JS, Foundation);
• iOS native (Swift);
• Android native (Java);
• Robotoff, our machine learning service

Principles

Our goal is to follow and keep few and simple guidelines.

1. discuss the topics or issues or functionalities you want to work on. The slack workspace is the best choice for it.
2. if not already done, open an issue on Github to explain the problem you want to solve or the functionality you want to work on.
3. if you want to work on an existing issue, tell everyone in the issue's Github comments.
4. fork the project and create one branch per issue or functionality you want to work on.
   1. It's cool to name a branch: issue/[issue_number]-[name]; ex.: issue/1630-name-of-the-issue
   2. When you're ready to propose something, send a "pull request"; be patient, sometimes it takes time to the core team to review pull request.
5. coding style is defined in the .editorconfig file, see https://github.com/openfoodfacts/openfoodfacts-server/blob/master/.editorconfig; many editors support EditorConfig, check yours: https://editorconfig.org
