-## Getting Started
+## Usage
 
-To get started using the action make sure you have the standard workflow structure set up (.github/workflows) create a file called `deploy.yml` with the following contents.
+```yaml
+- uses: quantcdn/action-deploy@v5
+  with:
+    customer: your-customer-id
+    project: your-project-name
+    token: ${{ secrets.QUANT_TOKEN }}
+    dir: build
+```

+          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"
+              },
+              {
+                "type": "edge",
+                "path": "./functions/edge.js",
+                "description": "Custom edge function",
+                "uuid": "019361ae-2516-788a-8f50-e803ff561c35"
+              },
+              {
+                "type": "filter",
+                "path": "./functions/filter.js",
+                "description": "Custom filter function",
+                "uuid": "019361ae-2516-788a-8f50-e803ff561c36"
+              }
+            ]
 ```
 
-Replace the placeholders with values for your project, these can be found in the [Quant dashboard](https://docs.quantcdn.io/docs/dashboard).
+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
 
-## Adding secrets
+Functions will automatically be deployed to `/fn/{uuid}`.
 
-Navigate to your repositories Settings page and find **Secrets**. Once there click on new secret, enter **QUANT_TOKEN** as the secret name and paste your provided Quant API token.
+### Functions Configuration
 
-You can learn more about [secrets](https://docs.github.com/en/actions/reference/encrypted-secrets) and [actions](https://docs.github.com/en/actions).
+You can configure functions either directly in the workflow or via a JSON file:
 
-## Inputs
+#### 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"
+              }
+            ]
 ```

-  default: 'false'
-enable-index-html:
-  description: 'Enable index.html creation in Quant (preserves 1.x functionality)'
-  required: false
-  default: false
+
+#### 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'
+```
+
+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}`.
+
+## Notes
+
+- This action uses Quant CLI v5
+- For search functionality, please use the dedicated search action
+- Make sure your `QUANT_TOKEN` is stored securely in your repository secrets
