+# TrashScan Explorer Stack
+
+TrashScan is a blockchain explorer for Gorbagana mainnet (Solana fork).
+
+## Quick Start
+
+```bash
+# 1. Setup repositories (clones TrashScan-Explorer to ~/cerc/)
+laconic-so --stack trashscan-explorer setup-repositories
+
+# 2. Build containers
+laconic-so --stack trashscan-explorer build-containers
+
+# 3. Deploy
+laconic-so --stack trashscan-explorer deploy-system up
+
+# 4. Verify
+docker ps --filter "name=trashscan"
+curl http://localhost:5001/
+
+# 5. View logs
+laconic-so --stack trashscan-explorer deploy-system logs -f
+
+# 6. Stop
+laconic-so --stack trashscan-explorer deploy-system down
+```
+
+## Access
+
+After deployment, access the explorer at: **http://localhost:5001**
+
+Note: Default port is 5001 to avoid conflict with macOS AirPlay Receiver on port 5000.
+
+## Components
+
+| Service | Image | Port | Description |
+|---------|-------|------|-------------|
+| trashscan-explorer | cerc/trashscan-explorer:local | 5001 | React/Express blockchain explorer |
+| trashscan-db | postgres:14-alpine | (internal) | PostgreSQL database |
+
+## Configuration
+
+Environment variables can be set in your deployment configuration:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| NODE_ENV | production | Node environment |
+| DATABASE_URL | postgres://trashscan:password@trashscan-db:5432/trashscan | Database connection string |
+| TRASHSCAN_HOST_PORT | 5001 | Host port for explorer |
+| SESSION_SECRET | change-me-in-production | Express session secret |
+| RPC_URL | https://rpc.trashscan.io/ | Gorbagana RPC endpoint |
+| RUN_MIGRATIONS | true | Run database migrations on startup |
+
+## External Dependencies
+
+The explorer connects to the Gorbagana RPC at https://rpc.trashscan.io/ by default.

+```
+
+## Verification Checklist
+
+After deployment, verify:
+
+- [ ] `docker ps` shows both containers as `(healthy)`
+- [ ] `curl http://localhost:5001/` returns HTTP 200
+- [ ] Logs show "TrashScan Explorer starting..." and "Database is available!"
+
+## Troubleshooting
+
+### Port 5000 conflict (macOS)
+macOS AirPlay Receiver uses port 5000. This stack defaults to 5001.
+To use a different port: `export TRASHSCAN_HOST_PORT=8080`
+
+### Missing assets error during build
+The upstream TrashScan-Explorer repo may be missing the `attached_assets/` directory.
+Create placeholder images if needed:
+```bash
+cd ~/cerc/TrashScan-Explorer
+mkdir -p attached_assets
+# Create placeholder images for any missing assets
+```
+
+### "Cannot find package 'vite'" error
+The Dockerfile.base includes vite in production deps to handle this.
