+# GitHub Repository Metadata
+
+Keep the repository's GitHub settings aligned with the public product contract.
+These fields are not derived from files, so a maintainer must update them in
+**Settings → General** when the positioning changes.
+
+## Description
+
+> Local, cited memory for Claude, Cursor, ChatGPT, and MCP agents—review what it learns and keep a readable vault you own.
+
+## Website
+
+Use the canonical product or documentation URL only when it is maintained and
+matches the current open-source release. Otherwise leave this blank rather than
+linking to an outdated landing page.

+## Social preview

+Upload [`assets/social-preview.png`](assets/social-preview.png). The same image

+two-minute visitor story stay visually consistent.
+
+## Release copy
+
+Lead with a concrete user outcome, name the supported platform, link the
+changelog, and repeat any material beta limitation. Do not use benchmark
+results as real-world quality claims.
