+# Keyboard Vagabond - Project Overview
+
+## System Overview
+This is a **Talos-based Kubernetes cluster** designed to host **fediverse applications** for <200 MAU (Monthly Active Users):
+- **Mastodon** (Twitter-like microblogging) ✅ OPERATIONAL
+- **Pixelfed** (Instagram-like photo sharing) ✅ OPERATIONAL  
+- **PieFed** (Reddit-like forum) ✅ OPERATIONAL
+- **BookWyrm** (Social reading platform) ✅ OPERATIONAL
+- **Matrix** (Chat/messaging) - Future deployment
+
+## Architecture Summary ✅ OPERATIONAL
+- **Three ARM64 Nodes**: n1, n2, n3 (all control plane nodes with VIP 10.132.0.5)
+- **Zero Trust Security**: Cloudflare tunnels + Tailscale mesh VPN
+- **Storage**: Longhorn distributed with S3 backup to Backblaze B2
+- **Database**: PostgreSQL HA cluster with CloudNativePG operator
+- **Cache**: Redis HA cluster with HAProxy (redis-ha-haproxy.redis-system.svc.cluster.local)
+- **Monitoring**: OpenTelemetry + OpenObserve (O2)
+- **Registry**: Harbor container registry
+- **CDN**: Per-application Cloudflare CDN with dedicated S3 buckets
