+## Vision
+
+Build a Mod Store with Git-based submissions, automated malware scanning, and policy checks before mods are visible.
+
+## Core principles
+
+- All submissions are reviewable in Git.
+- Every build artifact is reproducible from source.
+- Security checks are mandatory before publish.
+
+## Security pipeline (target)
+
+1. Submit via pull request (manifest + source + checksums).
+2. CI runs static checks and signature/metadata validation.
+3. Virus scanning runs on produced artifacts.
+4. Maintainer review and policy checks.
+5. Publish approved metadata index consumed by launcher/site.
+
+## Recommended metadata fields
+
+- `modId`, `version`, `authors`
+- `supportedGameVersions`
+- `requiredFrameworkVersion`
+- `sha256` for each downloadable artifact
+- source URL and license
