Clojure (the language) is distributed as a Java archive and runs on the JVM, thus you will need Java installed. If you don't have specific Java requirements, we recommend Java 21, the latest LTS release.
The installation links are here for the Clojure CLI which can be used to manage dependencies, run a REPL, etc:

If you are using WSL, then you'll want to follow the Linux instructions. If no WSL, use the clj-msi installer.
