+# Configuration
+## General
+In order to send a message via Telegram, you need to provide a `chat_id` and a `token`.
+If you don't pass them as parameters when calling functions from the execution module,
+they need to be defined inside the minion configuration or the pillar.
+These configuration values can be specified in either of the following ways:
+
+```yaml
+telegram:
+  chat_id: '123456789'
+  token: '00000000:xxxxxxxxxxxxxxxxxxxxxxxx'
+```
+
+```yaml
+telegram.chat_id: '123456789'
+telegram.token: '00000000:xxxxxxxxxxxxxxxxxxxxxxxx'
+```
+
+## Returner
+
+Using the returner module requires the above configuration values
+to be set in either the minion configuration or the pillar.
