-The `functions` input accepts a JSON array where each object must contain:
-- `type`: Either "auth", "filter", or "edge"
-- `path`: Path to the function file (e.g., "./functions/auth.js")
-- `description`: Description of the function
-- `uuid`: Valid UUID for the function
-
-Functions will automatically be deployed to `/fn/{uuid}`.
-
-### Functions Configuration
-
-You can configure functions either directly in the workflow or via a JSON file:
-
-#### Option 1: Direct Configuration
-
-```yaml
-      - name: Deploy to QuantCDN
-        uses: quantcdn/action-deploy@v5
-        with:
-          customer: your-customer-id
-          project: your-project-name
-          token: ${{ secrets.QUANT_TOKEN }}
-          dir: build
-          functions: |
-            [
-              {
-                "type": "auth",
-                "path": "./functions/auth.js",
-                "description": "Custom authentication function",
-                "uuid": "019361ae-2516-788a-8f50-e803ff561c34"
-              }
-            ]
-```
-
-#### Option 2: JSON File Configuration
-
-Create a JSON file (e.g., `functions.json`):
-```json
-[
-  {
-    "type": "auth",
-    "path": "./functions/auth.js",
-    "description": "Custom authentication function",
-    "uuid": "019361ae-2516-788a-8f50-e803ff561c34"
-  },
-  {
-    "type": "edge",
-    "path": "./functions/edge.js",
-    "description": "Custom edge function",
-    "uuid": "019361ae-2516-788a-8f50-e803ff561c35"
-  }
-]
-```
-
-Then reference it in your workflow:
-```yaml
-      - name: Deploy to QuantCDN
-        uses: quantcdn/action-deploy@v5
-        with:
-          customer: your-customer-id
-          project: your-project-name
-          token: ${{ secrets.QUANT_TOKEN }}
-          dir: build
-          functions-file: './functions.json'
+          functions: './functions.json'
 ```
 
-The function configuration requires:
-- `type`: Either "auth", "filter", or "edge"
-- `path`: Path to the function file (e.g., "./functions/auth.js")
-- `description`: Description of the function
-- `uuid`: Valid UUID for the function
-
-Functions will automatically be deployed to `/fn/{uuid}`.
