 #### Session
 
-There is support for sessions using `ActiveSupport::Cache` stores.
+This API is very close to ActiveController's session API, but works different
+under the hood. Cookies can not be used to store session id or
+whole session (like CookieStore does). So it uses key-value store and `session_key`
+method to build identifier from update.
+
+Store can be one of numerous `ActiveSupport::Cache` stores.
+While `:file_store` is suitable for development and single-server deployments
+without heavy load, it doesn't scale well. Key-value databases with persistance
+like Redis are more appropriate for production use.
 
 ```ruby
-# configure store in env files:
+# In rails app store can be configured in env files:
 config.telegram_updates_controller.session_store = :redis_store, {expires_in: 1.month}
 
+# In other app it can be done for all controllers with:
+Telegram::Bot::UpdatesController.session_store = :redis_store, {expires_in: 1.month}
+# or for specific one:
+OneOfUpdatesController.session_store = :redis_store, {expires_in: 1.month}
+```
+
+Default session id is made from bot's username and `(from || chat)['id']`.
+It means that session will be the same for updates from user in every chat,
+and different for every user in the same group chat.
+To change this behavior you can override `session_key` method, or even
+define multiple sessions in single controller. For details see `Session` module.

 class Telegram::WebhookController < Telegram::Bot::UpdatesController
