+## Contributing
+
+RapidJSON welcomes contributions. When contributing, please follow the code below.
+
+### Issues
+
+Feel free to submit issues and enhancement requests.
+
+Please help us by providing **minimal reproducible examples**, because source code is easier to let other people understand what happens.
+For crash problems on certain platforms, please bring stack dump content with the detail of the OS, compiler, etc.
+
+Please try breakpoint debugging first, tell us what you found, see if we can start exploring based on more information been prepared.
+
+### Workflow
+
+In general, we follow the "fork-and-pull" Git workflow.
+
+ 1. **Fork** the repo on GitHub
+ 2. **Clone** the project to your own machine
+ 3. **Checkout** a new branch on your fork, start developing on the branch
+ 4. **Test** the change before commit, Make sure the changes pass all the tests, including `unittest` and `preftest`, please add test case for each new feature or bug-fix if needed.
+ 5. **Commit** changes to your own branch
+ 6. **Push** your work back up to your fork
+ 7. Submit a **Pull request** so that we can review your changes
+
+NOTE: Be sure to merge the latest from "upstream" before making a pull request!
