 ### Requirements
 
-1.  [Java JDK >= 11](https://adoptium.net/temurin/releases/). **Not the JRE**.
-
-    1.  Ensure that the `java` command is in the PATH and is using version 11. For example:
-        ```bash
-        > java -version
-        openjdk version "11.0.21" 2023-10-17
-        OpenJDK Runtime Environment Temurin-11.0.21+9 (build 11.0.21+9)
-        OpenJDK 64-Bit Server VM Temurin-11.0.21+9 (build 11.0.21+9, mixed mode)
-        ```
-
-    2.  Next ensure that `java` is in a location where the jdk was installed and not just the jre. Use the `java --list-modules` command to do this. The list should contain `jdk.jshell`.
-
-        *   On *nix `java --list-modules | grep "jdk.jshell"`
-        *   On windows `java --list-modules | findstr "jdk.jshell"`
-
-        Both should output `jdk.jshell@` followed by your java version.
-
-    If the kernel cannot start with an error along the lines of
-    ```text
-    Exception in thread "main" java.lang.NoClassDefFoundError: jdk/jshell/JShellException
-            ...
-    Caused by: java.lang.ClassNotFoundException: jdk.jshell.JShellException
-            ...
-    ```
-    then double check that `java` is referring to the command for the `jdk` and not the `jre`.
-
