+# Contributing to fabric-chaincode-java
 
-We welcome contributions to the Hyperledger Fabric Project in many forms, and
-there's always plenty to do!
+We welcome contributions to the [Hyperledger Fabric](https://hyperledger-fabric.readthedocs.io) Project. There's always plenty to do!
 
-Please visit the
-[contributors guide](http://hyperledger-fabric.readthedocs.io/en/latest/CONTRIBUTING.html) in the
-docs to learn how to make contributions to this exciting project.
+If you have any questions about the project or how to contribute, you can find us in the [fabric-java-chaincode](https://chat.hyperledger.org/channel/fabric-java-chaincode) Hyperledger Rocket.Chat channel.
+
+Here are a few guidelines to help you contribute successfully...
+
+## Issues
+
+We currently track bug reports using the [Hyperledger JIRA](https://jira.hyperledger.org/issues/?jql=project+%3D+FAB+AND+component+%3D+fabric-chaincode-java) tool.
+
+If you find a bug which we don't already know about, you can help us by creating a new issue describing the problem. Please include as much detail as possible to help us track down the cause.
+
+> **Note:** Please use Rocket.Chat instead of JIRA to ask questions.
+
+## Fixes
+
+If you want to begin contributing code, looking through our open issues is a good way to start. Try looking for recent issues with detailed descriptions first, or ask us on Rocket.Chat if you're unsure which issue to choose.
+
+## Enhancements
+
+Make sure you have the support of the Hyperledger Fabric community before investing a lot of effort in project enhancements. For example, discuss your proposal on Rocket.Chat or open a JIRA issue for feedback before starting work.
+
+> **Note:** A more formal RFC process is under development for Hyperledger Fabric enhancement requests.
+
+## Pull Requests
+
+We use our own forks and [Github Flow](https://guides.github.com/introduction/flow/index.html) to deliver changes to the code. Follow these steps to deliver your first pull request:
+
+1. [Fork the repository](https://guides.github.com/activities/forking/#fork) and create a new branch from `master`.
+2. If you've added code that should be tested, add tests!
+3. If you've added any new features or made breaking changes, update the documentation.
+4. Ensure all the tests pass.
+5. Include the JIRA issue number, a descriptive message, and the [Developer Certificate of Origin (DCO) sign-off](https://github.com/probot/dco#how-it-works) on all commit messages.
+6. [Issue a pull request](https://guides.github.com/activities/forking/#making-a-pull-request)!
+7. [Azure DevOps](https://dev.azure.com/Hyperledger/Fabric-Chaincode-Java) builds must succeed before the pull request can be reviewed and merged.
+
+## Coding Style
+
+Please to try to be consistent with the rest of the code and conform to checkstyle rules where they are provided.
