+## Serum PUP Scenes Generator
+
+Serum PUP Scenes are a new feature of libserum_concentrate.
+Such scenes base on a defined number of fake frames at a given frame rate.
+These frames can be added to the ROM's original frames or overlay some original frames.
+The purpose is to add new animations or to replace existing frames with smoother aniations.
+Therefore, a colorization other needs a set of scene frames that could be colorized in the colorization editor.
+The `dmdutil-generate-scenes` tool generates a dump of such scene frames according to the PUP Scenes specification CSV file.
+
+`dmdutil-generate-scenes` accepts these command line options:
+```
+  -c, --csv=VALUE        PUP scenes CSV file to parse
+  -o, --output=VALUE     Output dump file to generate
+  -d, --depth=VALUE      Bit depth of the DMD frames (2 or 4) (optional, default is 2)
