+# Contributing to Hammer.js
+
+Looking to contribute something to Hammer.js? **Here's how you can help.**
+
+
+## Reporting issues
+
+We only accept issues that are bug reports or feature requests. Bugs must be
+isolated and reproducible problems that can be fixed within the Hammer.js.
+Please read the following guidelines before opening any issue.
+
+1. [**Read the documentation**](https://hammerjs.github.io)
+
+2. **Search for existing issues.** We get a lot of duplicate issues, and you'd
+help us out a lot by first checking if someone else has reported the same issue.
+Moreover, the issue may have already been resolved with a fix available. Also
+take a look if your problem is explained at the Wiki.
+
+3. **Create an isolated and reproducible test case.** Be sure the problem exists
+in Hammer's code with a reduced test case that should be included in each bug
+report.
+
+4. **Include a live example.** Make use of jsFiddle or jsBin to share your
+isolated test cases. Also, a screen capture would work, with tools like LICEcap.
+
+5. **Share as much information as possible.** Include operating system and
+version, browser and version, version of Hammer.js, customized or vanilla build,
+etc. where appropriate. Also include steps to reproduce the bug.
+
+## Pull requests
+
+1. Changes must be done in `/src` files, never just the compiled files. Also, don't
+commit the compiled files.
+
+2. Try not to pollute your pull request with unintended changes. Keep them simple
+and small
+
+3. Try to share which browsers your code has been tested in before submitting a
+pull request
+
+4. Write tests for your code, these can be found in `/tests`.
