 In this example, both sources and javadoc jar-files will be created during the build process.
 However, only the sources will get published to maven and uploaded to mod hosting websites.
 
+### Using JarJar as the main artifact
+
+By default, ModGradle uses the `jar` task as the main artifact for publishing and uploading.  
+You can switch to using the `jarJar` task (and optionally adjust classifiers) like this:
+
+```groovy
+artifacts {
+    useJarJar(true)
+}
+```
+
+This makes ModGradle use `jarJar` as the main artifact.
+With `true`, it also applies the common “thin + bundled” layout:
+
+- `jar` → `-thin`
+- `jarJar` → no classifier
+
+If you want to use `jarJar` without changing classifiers, call `useJarJar()` without arguments.

 ## resources
 
 The `resources` block allows to specify in which files parameter expansion should take place.
