+# How to contribute
+
+So you're thinking about contributing to NUnit? Great! Maintaining and enhancing NUnit is a big job, so **the community's help is really appreciated.**
+
+Helping out isn't just writing code, it also includes submitting issues, helping confirm issues, working on the website, helping people on the [mailing lists](https://groups.google.com/forum/m/#!forum/nunit-discuss) and improving the documentation. 
+
+## Submitting Issues
+
+Requests for new features and bug reports keep the project moving forward.
+
+### Before you submit an issue
+
+- Ensure you are running the [latest version](https://github.com/nunit/nunit/releases) of NUnit.
+- **Many 3rd party test runners do not support NUnit 3 yet.** They may appear to run NUnit tests, but they do not do so correctly.
+- To ensure that the bug is in NUnit and not in the runner you are using, **test your bug using the nunit3-console.exe** first.
+- If you are using the **Portable Framework**, the console runner nor the Visual Studio adapter do not run portable tests yet. You need to create an **NUnitLite** self-executing test or use the [NUnit Xamarin Runners](https://github.com/nunit/nunit.xamarin).
+- **Search** the [issue list](https://github.com/nunit/nunit/issues?utf8=%E2%9C%93&q=is%3Aissue) (including closed issues) to make sure it hasn't already been reported.
+
+### Submitting a good issue
+
+- Give the issue a short, clear title that describes the bug or feature request
+- Include what version of NUnit you are using
+- Tell us how you are running your tests including command line arguments for the console runner
+- Include steps to reproduce the issue
+- If possible, include a short code example that reproduces the issue
+- Use [markdown formatting](https://guides.github.com/features/mastering-markdown/) as appropriate to make the issue and code more readable.
+
+## Confirming Issues
+
+Before we work on issues, we must confirm them and be able to reproduce them. Confirming issues takes up a great deal of the team's time, so making that job easier is **really appreciated**.
+
+Issues that need confirmation will have the **confirm** label or be unlabeled and have **no milestone**. You can help us to confirm issues by;
+
+- Add steps to reproduce the issue
+- Create unit tests to demonstrate the issue
+- Test issues and provide feedback
+
+## Documentation
+
+Great documentation is essential for any open source project and NUnit is no exception. [Our documentation](https://github.com/nunit/nunit/wiki) often lags behind the features that have been implemented or would benefit from better examples.
+
+A great place to start is by going through the [NUnit release notes](https://github.com/nunit/nunit/wiki/Release-Notes) and ensuring that the documentation for new features is up to date.
+
+## Fixing Bugs and Adding Features 
+
+We love pull requests, but would prefer that new contributors start with smaller issues and let us know before you contribute to prevent duplication of work.
+
+To help new contributors get their feet wet, we have marked a number of issues with the `easyfix` label. These are great places to start.
+
+It is also a good idea to add a comment to an issue that you are working on to let everyone know. If you stop working on it, also please let us know.
+
+Please read through the [NUnit Dev Wiki]() before contributing to understand our coding standards and contribution guidelines.
+
+## License

+
+* The contribution is your own original work.
+* You have the right to assign the copyright for the work (it is not owned by your employer, or
