 I recommend running `auth persistence Encrypted` within the container to ensure that your authentication tokens are saved securely and persist across container restarts. Make sure to reauthenticate after running this command to store the tokens.
 
+## Configuration
+
+The following environment variables can be used to configure the Hytale server:
+
+| Variable                       | Default              | Description                                 |
+| ------------------------------ | -------------------- | ------------------------------------------- |
+| `HYTALE_MINIMUM_MEMORY`        | `128M`               | Minimum memory allocation for the JVM       |
+| `HYTALE_MAXIMUM_MEMORY`        | 90% of system memory | Maximum memory allocation for the JVM       |
+| `HYTALE_SERVER_PORT`           | `5520`               | Port the server binds to                    |
+| `HYTALE_PARAMETERS`            | _(see below)_        | Override all JVM/server parameters          |
+| `HYTALE_ADDITIONAL_PARAMETERS` | _(none)_             | Append additional parameters to the default |
+
+### Example with Custom Memory Settings
+
+```yaml
+services:
+  hytale:
+    image: ghcr.io/zuedev/hytale-server-docker
+    ports:
+      - "5520:5520/udp"
+    volumes:
+      - ./data:/app/Hytale
+    environment:
+      - HYTALE_MINIMUM_MEMORY=512M
+      - HYTALE_MAXIMUM_MEMORY=4096M
+    restart: unless-stopped
+    stdin_open: true
+    tty: true
+```
