-## Available Scripts
+## Admin User Management
+
+### Create Central Admin User
+
+```bash
+npm run create-central-admin
+```
+
+Creates an administrator user in the **central database**. Central admins can:
+- Manage tenants (create, update, delete)
+- Access platform-wide administration features
+- View all tenant information
+- Manage tenant provisioning
+
+**Interactive Mode:**
+```bash
+npm run create-central-admin
+# You will be prompted for:
+# - Email
+# - Password
+# - First Name (optional)
+# - Last Name (optional)
+# - Role (admin or superadmin)
+```
+
+**Non-Interactive Mode (using environment variables):**
+```bash
+EMAIL=admin@example.com PASSWORD=securepass123 FIRST_NAME=John LAST_NAME=Doe ROLE=superadmin npm run create-central-admin
+```
+
+**Logging In as Central Admin:**
+1. Access the application using a central subdomain (e.g., `central.yourdomain.com` or `admin.yourdomain.com`)
+2. Enter your central admin credentials
+3. You'll be authenticated against the central database (not a tenant database)
+
+**Note:** The system automatically detects if you're logging in from a central subdomain based on the `CENTRAL_SUBDOMAINS` environment variable (defaults to `central,admin`). No special UI or configuration is needed on the frontend.
+
+### Create Tenant User
+
+For creating users within a specific tenant database, use:
+```bash
+npm run create-tenant-user <tenant-slug>
+# (Note: This script may need to be created or already exists)
+```
