 > Converts MIDI files into music box scores that are ready to print.
 
+## Getting Started
+This program is written in C♯. To get started, first clone this repository and compile it:
+
+```bash
+git clone https://git.starbeamrainbowlabs.com/sbrl/MusicBoxConverter.git
+cd MusicBoxConverter
+msbuild
+```
+
+If you're on Windows, you'll either need to use a _Visual Studio Developer Command Prompt_ or open the solution file in _Visual Studio_ itself.
+
+Alternatively, you can 
+
+
 ## Usage
 1. Export the MuseScore file to a MIDI file
 2. Run the MIDI file through this program.
