 # Catalyst
 
-A self-hosted infrastructure registry. Track every VM, container, and service across your homelab — their state, stack, and which internal services are running on them.
+A self-hosted infrastructure registry for homelab Proxmox environments. Track virtual machines across stacks, monitor service health, and maintain a full audit log of every configuration change.

 ## Features
 
 - **Dashboard** — filterable, searchable instance list with state and stack badges
-- **Detail pages** — per-instance view with service flags, Tailscale IP, and timestamps
+- **Detail pages** — per-instance view with service flags, Tailscale IP, and a full change timeline
+- **Audit log** — every field change is recorded with before/after values and a timestamp
 - **Full CRUD** — add, edit, and delete instances via a clean modal interface
 - **Production safeguard** — only development instances can be deleted; production instances must be demoted first
-- **REST API** — every operation is a plain HTTP call; no magic, no framework lock-in
+- **Export / import** — JSON backup and restore via the settings modal
-- **Persistent storage** — SQLite database on a Docker named volume; survives restarts and upgrades
+- **REST API** — every operation is a plain HTTP call
-- **Zero native dependencies** — SQLite via Node's built-in `node:sqlite`. No compilation, no binaries.
