+# Contributing
+
+## Introduction
+
+We appreciate your interest in considering contributing to go (json-iterator).
+Community contributions mean a lot to us.
+
+## Contributions we need
+
+You may already know how you'd like to contribute, whether it's a fix for a bug you
+encountered, or a new feature your team wants to use.
+
+If you don't know where to start, consider improving
+documentation, bug triaging, and writing tutorials are all examples of
+helpful contributions that mean less work for you.
+
+## Your First Contribution
+
+Unsure where to begin contributing? You can start by looking through
+[help-wanted
+issues](https://github.com/json-iterator/go/issues).
+
+Never contributed to open source before? Here are a couple of friendly
+tutorials:

+
+## Getting Started
+
+Here's how to get started with your code contribution:
+
+1.  Create your own fork of go(json-iterator/go)
+2.  Do the changes in your fork
+3.  If you like the change and think the project could use it, send a
+    pull request
+
+### Troubleshooting
+
+If you get any errors when running, make sure
+that you are using supported versions of go.
+
+## How to Report a Bug
+
+### Security Vulnerabilities
+
+**NOTE**: If you find a security vulnerability, do NOT open an issue.
+Email [go (mailto:taowen@gmail.com) instead.
+
+
+### Everything Else
+
+When filing an issue, make sure to answer these four questions:
+
+1.  What version of go(json-iterator) are you using?
+2.  What did you do?
+3.  What did you expect to see?
+4.  What did you see instead?
+
+## Suggest a feature or enhancement
+
+If you'd like to contribute a new feature, make sure you check our
+issue list to see if someone has already proposed it. Work may already
+be underway on the feature you want or we may have rejected a
+feature like it already.
+
+If you don't see anything, open a new issue that describes the feature
+you would like and how it should work.
+
+## Code review process
+
+The core team regularly looks at pull requests. We will provide
+feedback as soon as possible. After receiving our feedback, please respond
+within two weeks. After that time, we may close your PR if it isn't
+showing any activity.
