 ## Server Registration
 
-Register migration servers:
+**Important:** Servers must be registered in the database (not just configured in `.env`).
+
+The `.env` file contains server configuration (TEMP01_HOST, TEMP02_HOST, etc.), but these are used by legacy code. The main automation system uses servers from the database.
+
+### Register Servers
+
+1. Edit `utils/register_servers.py` with your server details:
+   - `server_name`: Server identifier (TEMP01, TEMP02, TEMP03)
+   - `host`: Server hostname
+   - `api_url`: Server API URL
+   - `api_key`: Server API key
+   - `gwme_path`: GWME installation path
+   - `pst_folder`: PST export folder path
+   - `max_batch_size`: Maximum users per batch
+
+2. Run the registration script:
 
 ```bash
 python utils/register_servers.py
 ```
 
+This creates/updates server records in the `migration_servers` table.
+
+### Verify Registered Servers
+
+```bash
+python -m db_utils servers
+```
+
+Or query directly:
+
+```bash
+python -m run_sql "SELECT * FROM migration_servers"
+```
+
