-### Node Configurations
-
-#### `configs: Array<Config>`
-
-Array of node connection configurations:
-
-**Config Object Structure:**
-
-```javascript
-{
-  name: string,        // Display name for the node
-  url?: string,        // GraphQL endpoint URL (optional for WebNodes)
-  isWebNode?: boolean, // True for browser-based WebAssembly nodes
-}
-```
-
-**Examples:**
-
-```javascript
-// Regular node connection
-{

-  url: 'https://api.openmina.com/graphql'
-}
-
-// WebNode (browser-based)

-
-## Creating Custom Environments
-
-To create a new environment configuration:
-
-1. **Create the configuration file** in `frontend/src/assets/environments/`:
-
-   ```bash
-   cp frontend/src/assets/environments/local.js frontend/src/assets/environments/custom.js
-   ```
-
-2. **Modify the configuration** to suit your needs:
-
-   ```javascript
-   export default {
-     production: true,
-     canAddNodes: true,
-     globalConfig: {
-       features: {
-         dashboard: [],
-         "block-production": ["overview"],
-       },
-     },
-     configs: [
-       {
-         name: "Custom Node",
-         url: "https://your-node.example.com",
-       },
-     ],
-   };
-   ```
-
-3. **Add a Makefile target** (optional):
-
-   ```makefile
-   .PHONY: build-custom
-   build-custom: ## Build the frontend with custom configuration
-     npx ng build --configuration production
-     cp dist/frontend/browser/assets/environments/custom.js \
-       dist/frontend/browser/assets/environments/env.js
-   ```
-
-4. **Update Docker support** (if needed) by adding the environment to
-   `frontend/docker/startup.sh`.
