+# Postgre-TLS - Secure PostgreSQL Docker Setup with SSL/TLS
+
+A secure PostgreSQL Docker container with enforced SSL/TLS encryption, certificate verification, and advanced security features.
+
+## Features
+
+- **SSL/TLS Encryption**: TLSv1.3 with 256-bit AES-GCM encryption
+- **Certificate Verification**: Full SSL certificate verification enabled
+- **SCRAM-SHA-256 Authentication**: Secure password authentication
+- **Row-Level Security**: Built-in support for fine-grained access control
+- **Audit Logging**: Comprehensive audit trail for database operations
+- **Data Integrity**: Checksums enabled for data corruption detection
+- **Monitoring**: Built-in performance monitoring with pg_stat_statements
+- **Encryption Functions**: pgcrypto extension for additional encryption capabilities
+
+## Quick Start
+
+1. **Start the PostgreSQL container**:
+   ```bash
+   ./start.sh
+   ```
+
+2. **Connect to the database**:
+   ```bash
+   ./connect.sh
+   ```
+
+3. **Stop the container**:
+   ```bash
+   docker-compose down
+   ```
+
+## SSL Connection Details
+
+The setup provides enterprise-grade security with:
+- **Encryption**: TLSv1.3 with TLS_AES_256_GCM_SHA384 cipher
+- **Key Size**: 256-bit encryption
+- **Certificate**: Self-signed with full verification
+- **Authentication**: SCRAM-SHA-256 password hashing
+
+## Manual Connection
+
+You can also connect manually using psql:
+```bash
+psql "host=localhost port=5432 dbname=ploughgres user=ploughgres_user sslmode=verify-full sslrootcert=secrets/ca_crt"
+```
+
+For non-interactive connection, set the PGPASSWORD environment variable:
+```bash
+export PGPASSWORD=$(cat secrets/postgres_password || echo "change_me_in_production")
+psql "host=localhost port=5432 dbname=ploughgres user=ploughgres_user sslmode=verify-full sslrootcert=secrets/ca_crt"
+```

+# PloughGres Usage Guide
+
+## Quick Start
+
+1. **Start the PostgreSQL container:**
+   ```bash
+   ./start.sh
+   ```
+
+2. **Connect to the database:**
+   ```bash
+   ./connect.sh
+   ```
+
+3. **Stop the container:**
+   ```bash
+   docker-compose down
+   ```
+
+## Common Operations
+
+### Database Management
+- **View container status:** `docker ps`
+- **View container logs:** `docker logs ploughgres-db`
+- **Access PostgreSQL shell:** `./connect.sh`
+- **Restart container:** `docker-compose restart`
+
+### SSL Connection Testing
+The setup uses TLSv1.3 with 256-bit encryption. Connection details:
+- **Host:** localhost
+- **Port:** 5432
+- **Database:** ploughgres
+- **User:** ploughgres_user
+- **SSL Mode:** verify-full (certificate verification enabled)
+
+### Data Persistence
+- Database data is stored in `./data/` directory
+- SSL certificates are in `./secrets/` directory
+- All data remains in the project directory (userspace)
+
+### Security Features
+- ✅ SSL/TLS encryption (TLSv1.3)
+- ✅ Certificate verification
+- ✅ SCRAM-SHA-256 authentication
+- ✅ Row-level security enabled
+- ✅ Audit logging
+- ✅ Encryption functions (pgcrypto)
+
+## Troubleshooting
+
+### Container Issues
+- **Container won't start:** Check `docker logs ploughgres-db`
+- **Port conflicts:** Ensure port 5432 is available
+- **Permission issues:** Check file permissions in `secrets/` directory
+
+### SSL Connection Issues
+- **Certificate errors:** Verify certificates exist in `secrets/`
+- **Connection refused:** Ensure container is running and healthy
+- **Authentication failed:** Check password in `secrets/postgres_password.txt`
+
+## Development
+
+### Making Changes
+1. Stop the container: `docker-compose down`
+2. Make your changes
+3. Rebuild and restart: `./start.sh`
+
+### Viewing SSL Status
+Connect to the database and run:
+```sql
+SELECT ssl, version, cipher, bits FROM pg_stat_ssl WHERE pid = pg_backend_pid();
+```
+
+## Files Overview
+- `docker-compose.yml` - Container configuration
+- `start.sh` - Initialization and startup script
+- `connect.sh` - SSL connection test script
+- `Dockerfile` - Container image definition
+- `secrets/` - SSL certificates and passwords
+- `data/` - PostgreSQL data directory
