+
+### Fields structure
+
+Please reference the [WordPress settings API documentation](https://docs.woocommerce.com/document/settings-api/) to better understand the structure expected for the fields property. This component accepts the object returned via the `settings` property when querying a gateway via the API, or simply the array provided by `Object.values(settings)`.
+
+### Currently Supported Types
+
+-   Text
+-   Password
+-   Checkbox
+-   Select

+# WooRemotePaymentSettings Slot & Fill
+
+A Slotfill component that will replace the <Settings /> component involved in displaying the form while adding a gateway via the payment task.
+
+## Usage
+
+```jsx
+<WooRemotePaymentSettings id={ key }>
+  {({defaultSettings: DefaultSettings}) => <p>Fill Content</p>}
+</WooRemotePaymentSettings>
+
+<WooRemotePaymentSettings.Slot id={ key } />
+```
+
+### WooRemotePaymentSettings (fill)
+
+This is the fill component. You must provide the `id` prop to identify the slot that this will occupy. If you provide a function as the child of your fill (as shown above), you will receive some helper props to assist in creating your fill:
+
+| Name              | Type      | Description                                                                                               |
+| ----------------- | --------- | --------------------------------------------------------------------------------------------------------- |
+| `defaultSettings` | Component | The default instance of the <SettingsForm> component. Any provided props will override the given defaults |
+| `defaultSubmit`   | Function  | The default submit handler that is provided to the <Form> component                                       |
+| `defaultFields`   | Array     | An array of the field configuration objects provided by the API                                           |
+| `markConfigured`  | Function  | A helper function that will mark your gateway as configured                                               |
+
+### WooRemotePaymentSettings.Slot (slot)
+
+This is the slot component, and will not be used as frequently. It must also receive the required `id` prop that will be identical to the fill `id`.
+
+| Name        | Type   | Description                                                                        |
+| ----------- | ------ | ---------------------------------------------------------------------------------- |
+| `fillProps` | Object | The props that will be provided to the fills, by default these are described above |
