+**Multi-purpose Telegram Bot** is a telegram bot based on ASP.NET Core & [Telegram.Bot](https://github.com/TelegramBots/Telegram.Bot).
 
-**Multi-purpose Telegram Bot** is a telegram bot inside a ASP.NET Core app.
+The main idea of this bot is use of filter-handler architecture similar to ASP.NET routes and controllers.
 
-The main idea of this bot is use of a architecture where bot uses filters and corresponding handlers to handle updates received from Telegram.
+That way you don't need to put all your logic in a single controller.
 
-That way you don't need to have single handler that handles all kinds of messages.
-What you have is **the** router and many filters that decide what handler will handle new received message. Thus handlers have only one responsibility - get some information from a message and do something with it.
