+## Adding licence header to Muchos files
+
+Using [license-maven-plugin][license-plugin] we can generate a consistent license 
+header for the project with the following command.
+
+
+
+* Temporally convert the project to a maven project. Make sure not to commit the new `pom.xml` file.
+* Via command line, run the following command to generate the license header.
+```
+mvn com.mycila:license-maven-plugin:3.0:format -Dlicense.header=contrib/license-header.txt
+```
+
+* Check the output for warnings and manually add the appropriate license to those files.
