+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.
+
+Install Pyrogram
+----------------
+
+-   The easiest way to install and upgrade Pyrogram is by using **pip**:
+
+    .. code-block:: bash
+
+        $ pip3 install --upgrade pyrogram
+
+-   or, with TgCrypto_ (recommended):
+
+    .. code-block:: bash
+
+        $ pip3 install --upgrade pyrogram[tgcrypto]
+
+Bleeding Edge
+-------------
+
+If you want the latest development version of Pyrogram, you can install it straight from the develop_
+branch using this command:
+
+.. code-block:: bash
+
+    $ pip3 install --upgrade git+https://github.com/pyrogram/pyrogram.git
+
+Verifying
+---------
+
+To verify that Pyrogram is correctly installed, open a Python shell and import it.
+If no error shows up you are good to go.
+
+.. code-block:: bash
+
+    >>> import pyrogram
+    >>> pyrogram.__version__
+    '0.7.5'
