+Step 2x: Setup Telegram
+====================
+First you will need to create bot via [BotFather](https://telegram.me/BotFather) and then set you site domain to it
+
+```
+/newbot
+nameof_bot
+```
+
+Save token somewhere to put it as `client_secret` in config file
+
+```
+/setdomain
+example.com
+```
+Or you can do it via botfather buttons.
+
+Next configure a resource owner of type `telegram` with appropriate `client_secret`
+
+```yaml
+# config/packages/hwi_oauth.yaml
+
+hwi_oauth:
+    resource_owners:
+        any_name:
+            type:          telegram
+            client_id:     NOT_REQUIRED # but required by bundle
+            client_secret: <bot_token>
+```
+
+When you're done, continue by configuring the security layer or go back to
+setup more resource owners.
