 Example Maven multi-module project
 ===
 
+With multi-module projects the groupId becomes: com.github.User.Repo
+And artifactId remains the same as in the module's pom file.
 
+Module 1:
+```xml
+   <dependency>
+      <groupId>com.github.jitpack.maven-modular</groupId>
+      <artifactId>module1</artifactId>
+      <version>1.1</version>
+    </dependency>
+```
+
+Module 2:
+```xml
+    <dependency>
+      <groupId>com.github.jitpack.maven-modular</groupId>
+      <artifactId>module2</artifactId>
+      <version>1.1</version>
+    </dependency>
+```
+
+To get both of them together use the usual repository syntax:
+
+```xml
+    <dependency>
+      <groupId>com.github.jitpack</groupId>
+      <artifactId>maven-modular</artifactId>
+      <version>1.1</version>
+    </dependency>
+```
