+### Using custom Docker images
+
+You can override default Docker images using the `--config-file` flag. This is useful for testing custom builds or using specific versions without modifying the codebase.
+
+**Basic usage (without custom images):**
+```sh
+# Uses default images from validator-config.yaml in your network directory
+NETWORK_DIR=local-devnet ./spin-node.sh --node all --generateGenesis
+```
+
+**With custom config file:**
+```sh
+# Override specific node images
+NETWORK_DIR=local-devnet ./spin-node.sh --node all --generateGenesis --config-file user-config.yml
+```
+
+**Example config file (user-config.yml):**
+```yaml
+nodes:
+  - name: zeam_0
+    image: blockblaz/zeam:feature-branch
+  - name: ream_0
+    image: ghcr.io/reamlabs/ream:v2.0
+```
+
+**Testing a specific client build:**
+```sh
+# Create custom config file for zeam <your-PATH>/my-zeam-config.yml
+nodes:
+  - name: zeam_0
+    image: blockblaz/zeam:custom-tag
+
+# Run with custom zeam image
+NETWORK_DIR=local-devnet ./spin-node.sh --node zeam_0 --config-file <your-PATH>/my-zeam-config.yml
+```
+
+Only specify nodes you want to override - others will use their defaults from `validator-config.yaml`.
+
