 ## Install Additional Features
 
-1. Check what additional features are available for your current GraalVM Enterprise version:
+GraalVM Enterprise is shipped with core components (to save the filesize) and can be extended with more features on demand. For example, you can install Native Image, the Node.js runtime, the LLVM toolchain, etc. Find information on available features [here](https://docs.oracle.com/en/graalvm/enterprise/22/docs/overview/architecture/).
+
+To add additional features to GraalVM Enterprise, use the `yum install <package_name>` command. 
+
+1. Check what additional features are available for your current GraalVM Enterprise installation:
 
    ```shell
-   yum check-update
    sudo yum provides graalvm22*
    ```
-
-2. Look up the necessary RPM package name and add it to GraalVM Enterprise with the `yum install <package_name> command` command.
