+header: Creating a Simple module
+---
+
+## Explanation
+A simple module is a module which does not have any configuration whatsoever. You can add commands, listeners, and tasks to a module. In 
+order to begin creating a module you must first locate the `io/github/nucleuspowered/nucleus/modules` package. Next a new
+package must be created which will contain the new module. The package should be named the same or similar to the module ID. To finish with creating a very basic module all that needs doing is creating a new class in the package that extends `StandardModule`. Next the `@ModuleData` annotation must be added including a String id and name for the module. The `plugin` variable is automatically available for use in the module class.
+
+## Example
+
+```java
+package io.github.nucleuspowered.nucleus.modules.test;
+
+import io.github.nucleuspowered.nucleus.internal.qsml.module.StandardModule;
+import org.slf4j.Logger;
+import uk.co.drnaylor.quickstart.annotations.ModuleData;
+
+@ModuleData(id = "test", name = "Test Module")
+public class TestModule extends StandardModule {
+
+  @Override public void onEnable() {
+        super.onEnable();
+        Logger logger = this.plugin.getLogger();
+        logger.info("test module has been enabled!");
+    }
+}
+```
+The provided code above will load the module and the logger will print "test module has been enabled!" when the module is successfully
+enabled.
