+# Worker Config
+The worker config is a JSON file that is used to build the form that helps users configure their serverless endpoint on the RunPod Web Interface.
+
+Note: This is a new feature and only works for workers that use one model 
+
+## Writing your worker-config.json
+The JSON consists of two main parts, schema and versions.
+- `schema`: Here you specify the form fields that will be displayed to the user.
+  - `env_var_name`: The name of the environment variable that is being set using the form field.
+  - `value`: This is the default value of the form field. It will be shown in the UI as such unless the user changes it.
+  - `title`: This is the title of the form field in the UI.
+  - `description`: This is the description of the form field in the UI.
+  - `required`: This is a boolean that specifies if the form field is required.
+  - `type`: This is the type of the form field. Options are:
+    - `text`: Environment variable is a string so user inputs text in form field.
+    - `select`: User selects one option from the dropdown. You must provide the `options` key value pair after type if using this.
+    - `toggle`: User toggles between true and false.
+    - `number`: User inputs a number in the form field.
+  - `options`: Specify the options the user can select from if the type is `select`. DO NOT include this unless the `type` is `select`.
+- `versions`: This is where you call the form fields specified in `schema` and organize them into categories.
+  - `imageName`: This is the name of the Docker image that will be used to run the serverless endpoint.
+  - `minimumCudaVersion`: This is the minimum CUDA version that is required to run the serverless endpoint.
+  - `categories`: This is where you call the keys of the form fields specified in `schema` and organize them into categories. Each category is a toggle list of forms on the Web UI.
+    - `title`: This is the title of the category in the UI.
+    - `settings`: This is the array of settings schemas specified in `schema` associated with the category.
+
+## Example of schema
+```json
