+:::info Note
+If you find yourself asked to install the extension `altair-graphql-plugin-graphql-explorer`, allow this.
+This extension allows you to view and explore the GQL schema by opening the `GraphiQL Explorer` using the button midway down the left-side sidebar.
+The Explorer is useful for discovering and constructing available queries, mutations, and subscriptions.
+:::
+
+In the Query Window, click on "Pre-Request". Find this part of the script:
+
+```typescript
+const res = await altair.helpers.request(
+  'POST',
+  '/auth/login', // AUTH ENDPOINT OF THE DEPLOYMENT
+  {
+    body: { "username": "<YOUR_AERIE_USERNAME>", "password": "<YOUR_AERIE_PASSWORD>"}, // CREDENTIALS TO LOG IN AS
+    headers: {"Content-Type": "application/json"}
+  });
+```
+
+Replace `<YOUR_AERIE_USERNAME>` and `<YOUR_AERIE_PASSWORD>` with the username and password you use to sign in to Aerie.
+
+:::info Setting Your Role
+By default, you will make queries using the `viewer` role. If you want to use a different role,
+select `Set Headers` from the top of the left-side sidebar and update the header `x-hasura-role` to a different role you are permitted to use.
+
+To see the list of your permitted roles, use the following query:
+```gql
+{
+  users_and_roles {
+    username
+    hasura_allowed_roles
+  }
+}
+```
+
+After changing your role, you will need to press the `Reload Docs` button to the left of the `Send Request` button
+to update the list of available queries and mutations in the GraphiQL Explorer.
