+Installation
+============
+
+Being a Python library, Pyrogram requires Python to be installed in your system.
+We recommend using the latest version of Python 3 and pip.
+
+Get Python 3 from https://www.python.org/downloads/ or with your package manager and pip
+by following the instructions at https://pip.pypa.io/en/latest/installing/.
+
+Pyrogram supports Python 3 only, starting from version 3.4 and PyPy.
+

+-   The easiest way to install and upgrade Pyrogram is by using **pip**:

+
+    .. code-block:: bash
