+#### Options
+
+All options should go under the `Instagram` namespace.
+
+| name        | Type     | Required | Default | Description                                              |
+| ----------- | -------- | -------- | ------- | -------------------------------------------------------- |
+| accessToken | `string` | ✅       |         | An App Access Token (recommended) or Client Access Token |
+
+##### accessToken
+
+To get an App Access Token (recommended) or Client Access Token for the
+Instagram embed, check out the [Instagram oEmbed access token
+docs][instagram-oembed-access-token-docs] and
+[requirements][instagram-oembed-requirements-docs].
+
+The safest way to enter your `accessToken` is to set is as an [environment
+variable][gatsby-environment-variables-docs].
+
+<details>
+<summary><b>Example</b></summary>

+const GatsbyRemarkEmbedderOptions = {
+  services: {
+    Instagram: {
