+## Contributing
+
+We love pull requests from everyone, especially if they are to expand the available functionality or address one of the [open issues](https://github.com/cisco-open/test-telemetry-generator/issues). You will need the following to start with:
+* Github access, obviously
+* JDK 11
+* Gradle 5.6.4 or above
+
+Once you have the above setup:
+* Clone the project
+* Create a new branch on your local machine
+* Make the changes and add tests for your changes
+* Run all tests in your local using
+`./gradlew clean build test` for Linux/Mac
+`gradlew.bat clean build test` for Windows
+Doing this in local will ensure that the tests pass on the Github workflow too
+* Push your branch and open a pull request with a good description of the changes being made
+* Someone will review and we may suggest some changes, improvements or alternatives
+
+Thank you and happy coding!
