+## Contributing
+Please keep the [issue tracker](https://github.com/hakimel/reveal.js/issues) limited to **bug reports**.
+
+
+### General Questions and Support
+If you have questions about how to use reveal.js the best place to ask is in the [Discussions](https://github.com/hakimel/reveal.js/discussions). Anything that isn't a bug report should be posted as a dicussion instead.
+
+
+### Bug Reports
+When reporting a bug make sure to include information about which browser and operating system you are on as well as the necessary steps to reproduce the issue. If possible please include a link to a sample presentation where the bug can be tested.
+
+
+### Pull Requests
+- Should be submitted from a feature/topic branch (not your master)
+- Should follow the coding style of the file you work in, most importantly:
+  - Tabs to indent
+  - Single-quoted strings
+
+
+### Plugins
+Please do not submit plugins as pull requests. They should be maintained in their own separate repository. More information here: https://github.com/hakimel/reveal.js/wiki/Plugin-Guidelines
