+## How to contribute to Redmine DMSF plugin
+
+#### **Did you find a bug?**
+
+* **Ensure the bug was not already reported** by searching on GitHub under [Issues](https://github.com/danmunn/redmine_dmsf/issues).
+* If you're unable to find an open issue addressing the problem, [open a new one](https://github.com/danmunn/redmine_dmsf/issues/new). Be sure to include a **title and clear description**, as much relevant information as possible, **Redmine and the plugin version**, a part of the **production.log** related to the issue and **screen-shots**.
+
+#### **A wrong or missing translation?**
+
+* Feel free to update language files (_config/locales/*.yml_) in your mother language or languages you are familiar with and send them back to us via a **pull request**.
+
+#### **Do you want to patch the existing code?**
+
+* Make a new fork of the current development branch (_devel-x.x.x_). Make your changes and [create a pull request](https://github.com/danmunn/redmine_dmsf/compare). Only pull requests into the **development branch** except those fixing serious errors will be accepted.
