 1. `build-and-run.sh` which will build Mocha Doom and run it. You can use it as such: `./build-and-run.sh -iwad ~/DOOM2.WAD`. This is the preferred way to quickly test changes for developers.
 2. `build-jar.sh` which will build a JAR file. You can then run the JAR file as such: `java -jar mochadoom.jar -iwad ~/DOOM2.WAD`. This is the preferred way for distributing a Mocha Doom executable.
 
+### Build with Gradle
+
+[Gradle](https://gradle.org/) is a cross-platform build tool, which can be also used to run and build Mocha Doom.
+First of all, you have to install Gradle following its [installation notes](https://gradle.org/install/). After that you can use the following commands:
+
+* Run Mocha Doom: `gradle clean run`
+* Build a JAR file: `gradle clean build`
+  This creates a JAR file in the `build/libs/` folder.
+  You can then run the JAR file as such: `java -jar build/libs/mochadoom.jar -iwad ~/DOOM.WAD`.
