+# How to contribute to xterm.js
+
+- [Opening issues for bug reports or feature requests](#opening-issues)
+- [Contributing code](#contributing-code)
+
+## Opening issues
+
+The preferred way to report bugs or request features is to use
+[GitHub issues](http://github.com/sourcelair/xterm.js/issues). Before
+opening an issue, read these pointers.
+
+### Opening issues effectively
+
+- Include information about **the browser in which the problem occurred**. Even
+  if you tested several browsers, and the problem occurred in all of them,
+  mention this fact in the bug report. Also include browser version numbers and
+  the operating system that you're on.
+
+- Mention which release of xterm.js you're using. Preferably, try also with
+  the current HEAD of the master branch, to ensure the problem has not already been
+  fixed.
+
+- Mention precisely what went wrong. What did you expect to happen? What happened instead? Describe the
+  exact steps a maintainer has to take to make the problem occur.
+
+- If the problem can not be reproduced in the [demo of xterm.js](README.md#demo), please provide an HTML document that demonstrates the problem.
+
+- Be polite. Issues with an indignant or belligerent tone tend to be moved to the
+  bottom of the pile.
+
+## Contributing code
+
+- Make sure you have a [GitHub account](https://github.com/join)
+- Fork [xterm.js](https://github.com/sourcelair/xterm.js/)
+  ([how to fork a repo](https://help.github.com/articles/fork-a-repo))
+- Make your changes
+- If your changes are easy to test or likely to regress, add tests. Tests go into `test`, directory.
+- Follow the general code style of the rest of the project (see below).
+- Submit a pull request
+([how to create a pull request](https://help.github.com/articles/fork-a-repo)).
+  Don't put more than one feature/fix in a single pull request.
+

+   holder has explicitly granted the right to use it like this,
