+
+## What This Project Is
+
+**Personal Internet Cell (PIC)** — a self-hosted digital infrastructure platform. It manages DNS, DHCP, NTP, WireGuard VPN, email, calendar/contacts (CalDAV), file storage (WebDAV), reverse proxy (Caddy), a certificate authority, and container orchestration, all from a single API + React UI.
+
+## Common Commands
+
+```bash
+# Full stack
+make start          # docker-compose up -d
+make stop           # docker-compose down
+make restart        # docker-compose restart
+make status         # docker status + API health
+make logs           # docker-compose logs -f
+make build          # rebuild api image
+
+# Tests
+make test           # pytest tests/ api/tests/
+make test-coverage  # pytest with coverage HTML report
+make test-api       # pytest tests/test_api_endpoints.py
+pytest tests/test_<module>.py   # single test file
+
+# Local dev (no Docker)
+pip install -r api/requirements.txt
+python api/app.py                 # Flask API on :3000
+
+cd webui && npm install && npm run dev   # React UI on :5173 (proxies API to :3000)
+
+# WireGuard
+make show-routes
+make add-peer PEER_NAME=foo PEER_IP=10.0.0.5 PEER_KEY=<pubkey>
+make list-peers
+```
+
+## Architecture
+
+### Backend (`api/`)
+
+All service managers inherit `BaseServiceManager` (`api/base_service_manager.py`). This enforces a consistent interface: `get_status()`, `get_config()`, `update_config()`, `validate_config()`, `test_connectivity()`, `get_logs()`, `restart_service()`. When adding or modifying a service manager, follow this pattern.
+
+The `ServiceBus` (`api/service_bus.py`) is a pub/sub event system used for inter-service communication. Services publish events (e.g., `SERVICE_STARTED`, `CONFIG_CHANGED`, `PEER_CONNECTED`) and subscribe to events from dependencies. Dependency graph is declared in the bus — e.g., `wireguard` depends on `network`; `email` depends on `network` and `vault`.
+
+`ConfigManager` (`api/config_manager.py`) is the single source of truth. Config lives in `/app/config/cell_config.json` (mapped from `config/api/`). All managers read/write through ConfigManager, which validates against per-service schemas and maintains automatic backups.
+
+`LogManager` (`api/log_manager.py`) provides structured JSON logging with rotation (5 MB / 5 backups per service). Use it instead of `print()` or raw `logging`.
+
+`app.py` (2000+ lines) contains all Flask REST endpoints, organized by service. It runs a background health-monitoring thread.
+
+Service managers:
+- `network_manager.py` — DNS (CoreDNS), DHCP (dnsmasq), NTP (chrony)
+- `wireguard_manager.py` — VPN peer lifecycle, QR codes
+- `peer_registry.py` — peer registration/lookup
+- `routing_manager.py` — NAT, firewall rules, VPN gateway
+- `vault_manager.py` — internal certificate authority
+- `email_manager.py` — Postfix + Dovecot
+- `calendar_manager.py` — Radicale CalDAV/CardDAV
+- `file_manager.py` — WebDAV storage
+- `container_manager.py` — Docker SDK wrappers
+- `cell_manager.py` — top-level orchestration
+
+### Frontend (`webui/`)
+
+React 18 + Vite + Tailwind CSS. All API calls go through `src/services/api.js` (Axios). Vite dev server proxies `/api` to `localhost:3000`. Pages in `src/pages/`, shared components in `src/components/`.
+
+### Infrastructure
+
+`docker-compose.yml` defines 13 services on a custom bridge network `cell-network` (172.20.0.0/16). Cell IPs default to 10.0.0.0/24. Key ports: 53 (DNS), 80/443 (Caddy), 3000 (API), 5173/8081 (WebUI), 51820/udp (WireGuard), 25/587/993 (mail), 5232 (CalDAV), 8080 (WebDAV).
+
+Config files for each service live under `config/<service>/`. Persistent data is under `data/` (git-ignored). WireGuard configs are also git-ignored.
+
+## Testing
+
+Tests live in `tests/` (28 files). Use mocking (`pytest-mock`) for external system calls. Integration tests in `test_integration.py` require Docker services running.

+- **WireGuard tools** (`wg` binary, for key generation during install)
 - **2 GB+ RAM, 10 GB+ disk space**
-- **Ports**: 53, 80, 443, 3000, 51820
+- **Open ports**: 53 (DNS), 80/443 (HTTP/S), 3000 (API), 8081 (Web UI), 51820/udp (WireGuard)
 
-### 1. Clone and Setup
+### 1. Install
 
 ```bash
-git clone https://github.com/yourusername/PersonalInternetCell.git
-cd PersonalInternetCell
+git clone <repo-url> pic
+cd pic
 
-# Start with Docker (Recommended)
-docker-compose up --build

-### 2. Access Services
+`make setup` generates WireGuard keys, writes `config/wireguard/wg0.conf` and
+`config/api/cell_config.json`, and creates all data directories.
+`make start` brings up all 13 Docker containers.
 
-- **API**: http://localhost:3000
-- **Health Check**: http://localhost:3000/health
-- **Service Status**: http://localhost:3000/api/services/status
+### 2. Access
 
-### 3. Use the Enhanced CLI
+| Service | URL |
+|---------|-----|
+| Web UI | `http://<host-ip>:8081` |
+| API | `http://<host-ip>:3000` |
+| Health | `http://<host-ip>:3000/health` |
+
+On a WireGuard client: `http://mycell.cell` (or whatever your cell name is).
+
+### 3. Local dev (no Docker)
 
 ```bash
-# Show cell status
-python api/enhanced_cli.py --status
+pip install -r api/requirements.txt
+python api/app.py                          # API on :3000
 
-# Interactive mode
-python api/enhanced_cli.py --interactive
+cd webui && npm install && npm run dev     # React UI on :5173 (proxies API to :3000)
+```

-# Configuration wizard
-python api/enhanced_cli.py --wizard network
+## 🔗 Connecting Two Cells (PIC Mesh)
+
+Two PIC instances can form a mesh — full site-to-site WireGuard tunnels with
+automatic DNS forwarding so each cell's services are reachable from the other.
+
+### Install the second cell
+
+```bash
+# On the second host (different VPN subnet; port 51820 is fine — different machine)
+CELL_NAME=pic1 VPN_ADDRESS=10.1.0.1/24 make setup && make start
+```
+
+### Exchange invites (two pastes, two clicks)
+
+1. On **Cell A** → open Web UI → **Cell Network** → copy the invite JSON.
+2. On **Cell B** → **Cell Network** → paste into "Connect to Another Cell" → click **Connect**.
+3. On **Cell B** → copy its invite JSON.
+4. On **Cell A** → paste Cell B's invite → click **Connect**.
+
+Both cells now have:
+- A site-to-site WireGuard peer (AllowedIPs = remote cell's VPN subnet).
+- A CoreDNS forwarding block so `*.pic1.cell` resolves across the tunnel.
+
+The **Connected Cells** panel shows live handshake status (green = online).
+
+### Same-LAN tip
+
+If both cells share the same external IP (behind NAT), the auto-detected
+endpoint in the invite will be the public IP. Replace it with the LAN IP
+before clicking Connect so traffic stays local:
+
+```json
+{ "endpoint": "192.168.31.50:51820", ... }
 ```
