 This role automates the setup of a Java Development Kit (JDK) on a host. It can optionally install the JDK packages from various providers (OpenJDK, Oracle, Azul), handle version management, and perform post-installation configuration. For older JDK versions (9 and below), it can also enable the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy to support stronger encryption.
 
+This role also verifies the JDK on target host against the official Cloudera on-premises support matrix, which is available at [supportmatrix.cloudera.com/](https://supportmatrix.cloudera.com). It is designed to be run early in a deployment pipeline to ensure that the environment meets the JDK prerequisites before proceeding with the installation of Cloudera products.
+
 The role will:
 - Install the specified JDK packages if `jdk_install_packages` is `true`.
 - For JDK versions 8 and below, it will apply the JCE Unlimited Strength Jurisdiction Policy if needed, by modifying `java.security` files.
 - If multiple `java.security` files are found during JCE configuration, it will either proceed or halt based on the `jdk_security_paths_override` flag.
 - For JDKs installed from Cloudera's repository, the role will ensure that any missing symbolic links are created to support a consistent JDK installation path.
+- Compare JDK against the support matrix at [supportmatrix.cloudera.com/](https://supportmatrix.cloudera.com) for the specified versions of Cloudera Manager and Cloudera Runtime.
 
 # Requirements
 
 - Root or `sudo` privileges are required to install packages and modify system-wide configuration files.
 - Network access to the package repositories for the chosen JDK provider.
