How do you put songs on stepmania?

To add songs to StepMania, first download the song files, which typically come in .zip or .rar formats. Extract the files, then place the song folders into the "Songs" directory within your StepMania installation folder. Ensure that each song folder contains a .sm (StepMania file) and an accompanying music file (like .mp3). Finally, launch StepMania, and the new songs should appear in the song selection menu.
