 Consider supporting our development by buying Iris on spigot! We work hard to make Iris the best it can be for everyone.

+1. Install [Java JDK 21](https://www.oracle.com/java/technologies/javase/jdk21-archive-downloads.html)
 2. Set the JDK installation path to `JAVA_HOME` as an environment variable.
     * Windows
         1. Start > Type `env` and press Enter

         2. Run `sudo nano ~/.zshenv`
         3. Add `export JAVA_HOME=$(/usr/libexec/java_home)` as a new line
         4. Use `CTRL + X`, then Press `Y`, Then `ENTER`
         5. Quit & Reopen Terminal and verify with `echo $JAVA_HOME`. It should print a directory
-3. If this is your first time building Iris for MC 1.18+ run `gradlew setup` inside the root Iris project folder.
-   Otherwise, skip this step. Grab a coffee, this may take up to 5 minutes depending on your cpu & internet connection.
-4. Once the project has setup, run `gradlew iris`
-5. The Iris jar will be placed in `Iris/build/Iris-XXX-XXX.jar` Enjoy! Consider supporting us by buying it on spigot!

 ### IDE Builds (for development)
 
-* Run `gradlew setup` any time you get dependency issues with craftbukkit
-* Configure ITJ Gradle to use JDK 17 (in settings, search for gradle)
+* Configure ITJ Gradle to use JDK 21 (in settings, search for gradle)
 * Add a build line in the build.gradle for your own build task to directly compile Iris into your plugins folder if you
   prefer.
 * Resync the project & run your newly created task (under the development folder in gradle tasks!)
