Preface
=======

.. rubric:: What is this?

Telegram is a popular messaging application.
This library is meant to make it easy for you to write Python programs that can interact with Telegram.
Think of it as a wrapper that has already done the hard work for you, so you can focus on developing an application.


.. rubric:: How should I use the documentation?

This documentation is divided in multiple sections. The first few sections are a guide, while others contain the API reference or a glossary of terms.
The documentation assumes some familiarity with Python.

If you are getting started with the library, you should follow the documentation in order by pressing the "Next" button at the bottom-right of every page.

You can also use the menu on the left to quickly skip over sections if you're looking for something in particular or want to continue where you left off.
