+This repository contains a handful of prototypes for the Go vulnerability database,
+as well as a initial set of vulnerability reports. Some of these packages can probably
+be coalesced, but for now are easier to work on in a more segmented fashion.
+
+* `reports` contains TOML security reports, the format is described in `format.md`
+* `report` provides a package for parsing and linting TOML reports
+* `osv` provides a package for generating OSV-style JSON vulnerability entries from a `report.Report`
+* `client` contains a client for accesing HTTP/fs based vulnerability databases, as well as a minimal caching implementation
+* `cmd/gendb` provides a tool for converting TOML reports into JSON database
+* `cmd/genhtml` provides a tool for converting TOML reports into a HTML website
+* `cmd/linter` provides a tool for linting individual reports
+* `cmd/report2cve` provides a tool for converting TOML reports into JSON CVEs
