In plain English

Telegram.Bot is a C# library for building bots that operate inside the Telegram messaging app. Telegram provides an official API that lets developers create automated accounts capable of receiving messages, sending replies, handling commands, processing payments, and more. This library wraps that API so .NET developers can interact with it using C# code rather than constructing raw HTTP requests by hand. The library is the most widely used .NET client for this purpose and is available as a NuGet package, which is the standard way of distributing reusable code in the .NET ecosystem. It targets .NET Standard 2.0 as a minimum, meaning it works with a wide range of .NET versions, though .NET 8 or newer is recommended for current projects. The library currently covers Telegram Bot API version 10.0. Adding the package to a project gives access to a client object you use to send messages, respond to user input, manage chat groups, handle file uploads, and call any other method the Telegram Bot API supports. The README points to a quickstart guide and a separate examples repository for getting started. The test suite doubles as documentation: the tests are written to show how each API method works, so reading them teaches the library at the same time it verifies correctness. Two optional extension packages add support for Telegram Login Widget (a way to let users authenticate on your website using their Telegram account) and Telegram Passport (a system for securely transmitting identity documents). There is also a community support chat on Telegram for questions about building bots with this library.
