+### Configuration
+
+While clients can be instantiated explicitly, there is `Telegram.bots_config=` method
+to configure app-wide clients, which are accessible via `Telegram.bots`.
+It accepts hash of `{bot_id: bot_config}`, and there is special id `:default`
+which is used for `Telegram.bot`.

+```ruby
+Telegram.bots_config = {
+  default: DEFAULT_BOT_TOKEN,
