Contribute Code to Omeka
Omeka's development is coordinated though GitHub.
The core code of Omeka Classic is available in a public GitHub repository. Please feel free to fork the code, issue pull requests, and submit issues there.
All add-ons maintained by the Omeka team are also available on GitHub, in the Omeka organization. Each plugin and theme has its own separate repository.
