+## How To Solve
+
+The main function contains a bunch of calls to dot, dash and space. These represent 
+more code. You can decompile
+this code with a tool such as ghydra and copy the calls into a text file, convert those calls
+to actual ".", "-" and " "'s and then interpret that using an online morse decoder.
