+**Repository:** [github.com/monster-penguin/BIOS-Preservation-Tool](https://github.com/monster-penguin/BIOS-Preservation-Tool)
+**License:** MIT
+
+A local tool for managing your own BIOS collection. Point it at your files, it verifies them against RetroBIOS platform YAMLs, stores them in a deduplicated database, and produces ready-to-use directories for each platform. Supports scanning directories, archives, and URLs.
+
+See the project's [README](https://github.com/monster-penguin/BIOS-Preservation-Tool#readme) for setup and usage.
