+# Custom Main
+To create your own application using EvoAl, you can create a custom main class. Therefore, you implement the `MainClass`, and annotate the class using  CDI annotations:
+
+```java
+import javax.enterprise.context.ApplicationScoped;
+import javax.inject.Named;
+
+import de.evoal.core.api.cdi.MainClass;
+
+@ApplicationScoped
+@Named("my-main")
+public class DataGenerator implements MainClass {
+	@Override
+	public void run() {
+        // your main application code goes here
+    }
+}
+```
+
+You have to pass the parameter ```-Bcore:main=my-main``` to EvoAl so it creates, initialises and starts your main class.
