 Working on your first Pull Request? You can learn how from this *free* series, [How to Contribute to an Open Source Project on GitHub](https://egghead.io/series/how-to-contribute-to-an-open-source-project-on-github).
 
+## Getting started with the code
+
+To start development of a new feature or fix, check out the repository with Git and start editing the code in your favorite IDE.
+
+Once you're done editing, you will need a Java 16 JDK as well as Maven to build and run the code. Ensure that the `JAVA_HOME` environment variable is set to your Java 16 JDK path and run the following command to build and execute Asciidocfx: `mvn clean javafx:run -Djavafx.scope=compile`
+
 ## Submitting code
 
 Any code change should be submitted as a pull request. The description should explain what the code does and give steps to execute it. The pull request should also contain tests.
