 `soundtrack` is currently in **alpha** and such is very likely to fail in common scenarios. You can give it a try for your DMF -> ESF conversion requirements, but as of now it may not work for all tracks. In my experience, 80% of tracks using effects supported will play properly. I will fix these issues as I encounter them while converting compositions for my Sega Mega Drive homebrew game, or as issues are reported in the issue tracker. Thank you for your patience!

-## Roadmap
+## Quick Start
+### Get help and supported options
+```
+reskit soundtrack --help
+```
+
+### Convert a single DMF module to ESF format
+```
+reskit -i track.dmf -o track.esf
+```
+
+## `soundtrack` Roadmap
 The eventual vision of `reskit` is to serve as an ffmpeg-like tool for converting assets to and from 8-bit and 16-bit console media formats. `soundtrack` aims to eventually support the following:
 * VGM format conversions
    * E.g. VGM to ESF, ESF to VGM. Build a sequence from VGM so that developers can make use of features offered by their sound engines, such as FM and PSG sound effects.
