+#How to Use
+Open the zip and extract all contents to a folder.
+
+Double-click `osuMapCombiner.jar` or open a command prompt/terminal window and type the following: `java -jar osuMapCombiner.jar` to start the application.
+
+Then find and add your maps to the interface (can be drag and dropped in). Once that's done generate your marathon and you will be ready to play it!
+
+##Troubleshooting
+osuMapCombiner requires Java 8 or higher. If you cannot get the application to run, please update your Java version or install a later release of Java.
