 # SMtoJSON
+
+SMtoJSON is a tool to convert .SM files (beatmaps for the Step Mania game) to a json format. The json format can be used for the game "Color Strike"
+
+# Usage
+
+Usage is quit simple. You only have to add a argument for the directory which contains .sm files. The tool wil automaticly create the json files and copy the sound andd images to a specific directory.
