 ## Compiling
 
 Prerequisites:
-- JDK 17 or newer
+- JDK 25 or newer
-
-From the File Explorer:
-1. Download and extract the project zip
-2. Download the core from https://gitlab.com/distant-horizons-team/distant-horizons-core and extract into a folder called `coreSubProjects`
-3. Open a terminal emulator in the project folder (On Windows you can type `cmd` in the title bar)
-4. Run the commands: `./gradlew assemble` (You may need to use a `.\` on Windows)
-5. Merge the jars with `./gradlew mergeJars`
-6. The compiled jar file will be in the folder `Merged`
 
 From the command line:
 1. `git clone --recurse-submodules https://gitlab.com/distant-horizons-team/distant-horizons.git`
 2. `cd distant-horizons`
 3. `./gradlew assemble`
-4. `./gradlew mergeJars`

 >Note: You can add the argument `-PmcVer=?` to tell gradle to build a selected MC version instead of having to modify the `gradle.properties` file.\
 > For example: `./gradlew assemble -PmcVer=1.18.2`
 
 <br>
 
-## Compiling with Docker
-
-`./compile <version>`
-
-You can also locally compile the DH jars without a Java environment by using Docker. Where `<version>` is the version of Minecraft to compile for (ie `1.20.1`), or the keyword `all`. See [Versions](#minecraft-and-library-versions) for a list of all supported values.
-
-<br>
-
 ## Other commands
 
-`./gradlew --refresh-dependencies` to refresh local dependencies.
-
-`./gradlew clean` to delete any compiled code.
-
-<br>
-
-## Note to self
-
-The Minecraft source code is NOT added to your workspace in an editable way. Minecraft is treated like a normal Library. Sources are there for documentation and research purposes only.
-
-Source code uses Mojang mappings & [Parchment](https://parchmentmc.org/) mappings.
-
-To generate the source code run `./gradlew genSources` <br>
-If your IDE fails to auto-detect the source jars when browsing Minecraft classes; manually select the JAR file ending with -sources.jar when prompted by your IDE. <br>
-(In IntelliJ it's at the top where it says "choose sources" when browsing a Minecraft class)
-
-<br>
-
-## Other Useful commands
-
 Run the standalone jar: `./gradlew run` <br>
 Build the standalone jar: `./gradlew core:build` <br>
 Only build Fabric: `./gradlew fabric:assemble` or `./gradlew fabric:build` <br>
 Only build Forge: `./gradlew forge:assemble` or `./gradlew forge:build` <br>
 Run the Fabric client (for debugging): `./gradlew fabric:runClient` <br>
 Run the Forge client (for debugging): `./gradlew forge:runClient` <br>
+Delete all compiled code: `./gradlew clean` <br>
+Refresh local dependencies: `./gradlew --refresh-dependencies`
 
-To build all versions: `./buildAll` (all builds will end up in the `Merged` folder)
