-# AutoStepper
-Tool to automate StepMania SM generation
+AutoStepper is a Java console program designed to automatically create StepMania SM files with these features:
+
+    Generate all difficulty levels
+    Generate holds & jumps
+    Obtain banner & background art
+    Run locally without interaction
+    Process multiple music files at once
+    Multiple beat detection methods
+    Cross-platform support
+
+So, here it is -- AutoStepper by Phr00t's Software (www.phr00t.com). You can get the whole built program under the "dist" folder.
+
+It works on a common line with arguments, which are all optional. If you just run the Java program, it will scan & process all mp3s (and wavs) in the current directory, and spit out folders for each song in the same directory (90 seconds worth of steps).
+
+The arguments are:
+
+input=[file/dir] output=[songs dir] duration=[seconds to process] synctime=[offset start time in seconds] tap=[true/false]
+
+If you set tap=true, AutoStepper won't try and automatically calculate the BPM or offset, and will instead prompt you to hit ENTER along with 30 consecutive beats. AutoStepper will then do the rest.
+
+It is best to let AutoStepper run through a whole bunch of music, and ones that it might not get exactly right -- to then pull out & use tap=true on them.
+
+You can also use the output as a base to further edit & perfect songs, with AutoStepper doing most of the dirty work.
+
+I will add it is optimized for pad use, not keyboard use (e.g. difficulty isn't high enough). Enjoy, it is free!
