+## Environment Variables Configuration
+
+SurfSense Docker setup supports configuration through environment variables. You can set these variables in two ways:
+
+1. Create a `.env` file in the project root directory (copy from `.env.example`)
+2. Set environment variables directly in your shell before running Docker Compose
+
+The following environment variables are available:
+
+```
+# Frontend Configuration
+FRONTEND_PORT=3000
+NEXT_PUBLIC_API_URL=http://backend:8000
+
+# Backend Configuration
+BACKEND_PORT=8000
+
+# Database Configuration

+POSTGRES_PASSWORD=postgres
+POSTGRES_DB=surfsense

+
+# pgAdmin Configuration
+PGADMIN_PORT=5050
+PGADMIN_DEFAULT_EMAIL=admin@surfsense.com
+PGADMIN_DEFAULT_PASSWORD=surfsense
+```
+
 ## Setup
 
 1. Make sure you have all the necessary environment variables set up:
    - Copy `surfsense_backend/.env.example` to `surfsense_backend/.env` and fill in the required values
    - Copy `surfsense_web/.env.example` to `surfsense_web/.env` and fill in the required values
+   - Optionally: Copy `.env.example` to `.env` in the project root to customize Docker settings
 
 2. Build and start the containers:

 The PostgreSQL database with pgvector extensions is available at:
 - Host: localhost
-- Port: 5432
-- Username: postgres
-- Password: postgres
-- Database: surfsense
+- Port: 5432 (configurable via POSTGRES_PORT)
+- Username: postgres (configurable via POSTGRES_USER)
+- Password: postgres (configurable via POSTGRES_PASSWORD)
+- Database: surfsense (configurable via POSTGRES_DB)
 
-You can connect to it using any PostgreSQL client.
+You can connect to it using any PostgreSQL client or the included pgAdmin.
+
+## pgAdmin
+
+pgAdmin is a web-based administration tool for PostgreSQL. It is included in the Docker setup for easier database management.
+
+- URL: http://localhost:5050 (configurable via PGADMIN_PORT)
+- Default Email: admin@surfsense.com (configurable via PGADMIN_DEFAULT_EMAIL)
+- Default Password: surfsense (configurable via PGADMIN_DEFAULT_PASSWORD)
+
+### Connecting to the Database in pgAdmin
+
+1. Log in to pgAdmin using the credentials above
+2. Right-click on "Servers" in the left sidebar and select "Create" > "Server"
+3. In the "General" tab, give your connection a name (e.g., "SurfSense DB")
+4. In the "Connection" tab, enter the following:
+   - Host: db
+   - Port: 5432
+   - Maintenance database: surfsense
+   - Username: postgres 
+   - Password: postgres
+5. Click "Save" to establish the connection
 
 ## Troubleshooting
 
 - If you encounter permission errors, you may need to run the docker commands with `sudo`.
-- If ports are already in use, modify the port mappings in the `docker-compose.yml` file.
+- If ports are already in use, modify the port mappings in the `.env` file or directly in the `docker-compose.yml` file.
 - For backend dependency issues, you may need to modify the `Dockerfile` in the backend directory.
-- For frontend dependency issues, you may need to modify the `Dockerfile` in the frontend directory. 
+- For frontend dependency issues, you may need to modify the `Dockerfile` in the frontend directory.
+- If pgAdmin doesn't connect to the database, ensure you're using `db` as the hostname, not `localhost`, as that's the Docker network name.
