+## Usage
+
+```js
+auth: {
+  strategies: {
+      aad: {
+        clientId: process.env.AAD_CLIENT_ID,
+        clientSecret: process.env.AAD_CLIENT_SECRET,
+        tenantId: process.env.AAD_TENANT_ID,
+        grantType: 'authorization_code'
+      },
+  }
+}
+```
+
+Anywhere in your application logic:
+
+```js
+this.$auth.loginWith('aad')
+```
+
+💁 This provider is based on [oauth2 scheme](../schemes/oauth2.md) and supports all scheme options.
+
+## Obtaining configs
+
+You need to create an app registration from Azure Portal and make sure to set up everything for an OAuth app in the usual way. e.g. whitelist urls.
