+Oracle GraalVM provides more technologies such as the Javascript runtime, Java on Truffle, etc., each of which can be installed as an add-on.
 
 1. Check what additional features are available for your current Oracle GraalVM installation:
 
    ```shell
-   sudo yum list graalvm-20*
+   sudo yum list graalvm-21*
    ```
    ```shell
-   dnf list graalvm-20*
+   dnf list graalvm-21*
    ```
    The printed list may be large. If you are interested in a particular feature, for example, the Python runtime, narrow down the search providing the exact package name:
 
    ```shell
-   sudo yum list graalvm-20-python*
+   sudo yum list graalvm-21-python*
    ```
    ```shell
-   dnf list graalvm-20-python*
+   dnf list graalvm-21-python*
    ```
 
 2. Install the feature to Oracle GraalVM using its `<package_name>`. For example, to install the Python runtime with `yum`, run:
    ```shell
-   sudo yum install graalvm-20-python
+   sudo yum install graalvm-21-python
    ```
    With `dnf`:
    ```shell
-   dnf install graalvm-20-python
+   dnf install graalvm-21-python
    ```
    Confirm that the installed package size is correct by entering `yes` at the prompt.
