# serum-preset-packager

> serum-preset-packager reads and writes Serum 2 preset files using a format the author reverse engineered. Its Python CLI decompresses a preset into editable JSON, packs JSON back into a preset, or opens an edit cycle. The documented container has an XferJson metadata header and a Zstandard-compressed CBOR payload.
