+# Versioning and Compatibility
+
+Although you can use omise-java with other Java versions, we have validated the following versions in our CI pipeline to ensure compatibility and stability.
+
+### Java Runtime Version(s) Supported
+
+Represents the java version that needs to be installed on your local in order to be able to run the precompiled java byte code inside your project. i.e Installing the SDK in your project from maven and running it in your custom project.
+
+### Minimum Java Version Required for Compilation
+
+Represents the Java version required to compile the SDK after you clone the SDK's repo or fork it.
