 ## Usage
 
+### 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,
+  chat: {token: CHAT_BOT_TOKEN, username: 'chatbot'},
+}
+
+Telegram.bot.get_updates
+Telegram.bot == Telegram.bots[:default] # true
+Telegram.bots[:chat].send_message(...)

+For Rails >= 5.2 `Telegram::Bot` searches for config first in credentials and then in secrets.
+To use credentials as config store, add telegram section to credentials instead of secrets using
+`rails credentials:edit`. In this case be aware of that [Rails < 6.0 may not load
+credentials in dev environment by default](https://github.com/telegram-bot-rb/telegram-bot/issues/74#issuecomment-384205609).
+In Rails >= 6.0 run `rails credentials:edit --environment development` to configure bot
+in each environment.
+
+I suggest not using Rails 5.2 credentials because it can lead to leakage of sensitive data
+and it's more difficult to use in multiple environments. See
+[secure_credentials](https://github.com/printercu/secure_credentials) gem for better option.
+
 From now clients will be accessible with `Telegram.bots[:chat]` or `Telegram.bots[:auction]`.
 Single bot can be accessed with `Telegram.bot` or `Telegram.bots[:default]`.

-### Botan.io metrics
-
-Initialize with `bot = Telegram::Bot::Client.new(token, botan: 'botan token')`
-or just add `botan` key in `secrets.yml`:
-
-```yml
-  telegram:
-    bot:
-      token: bot_token
-      botan: botan_token
-```
-
-Access to Botan client with `bot.botan`.
-Use `bot.botan.track(event, uid, payload)` to track events.
-
-There are some helpers for controllers in `Telegram::Bot::Botan::ControllerHelpers`:
-
-```ruby
-class Telegram::WebhookController < Telegram::Bot::UpdatesController
-  include Telegram::Bot::Botan::ControllerHelpers
-
-  # This will track with event: action_name & data: payload
-  before_action :botan_track_action
-
-  def smth(*)
-    # This will track event for current user only when botan is configured.
-    botan_track :my_event, custom_data
-
-    # or get access directly to botan client:
-    botan.track(...)
-  end
-end
-```
-
-There is no stubbing for botan clients, so don't set botan token in tests.
-
 ### Async mode
 
 There is built in support for async requests using ActiveJob. Without Rails
 you can implement your own worker class to handle such requests. This allows:
