+About
+-----
+
+Pyrogram is a fully functional Telegram Client Library written from the ground up in Python.
+It offers **simple** and **complete** access to the Telegram Messenger API and is designed for Python developers
+keen on building custom Telegram applications.
+
+Features
+--------
+
+-   **Easy to setup**: Pyrogram can be easily installed and upgraded using **pip**, requires
+    a minimal set of dependencies (which are also automatically managed) and very few lines
+    of code to get started with.
+
+-   **Easy to use**: Pyrogram provides idiomatic, developer-friendly, clean and readable
+    Python code (either generated or hand-written) making the Telegram API simple to use.
+
+-   **High level**: Pyrogram automatically handles all the low-level details of
+    communication with the Telegram servers by implementing the
+    `MTProto Mobile Protocol v2.0`_ and the mechanisms needed for establishing
+    a reliable connection.
+
+-   **Fast**: Pyrogram's speed is boosted up by `TgCrypto`_, a high-performance, easy-to-install
+    crypto library written in C.
+
+-   **Updated**: Pyrogram makes use of the latest Telegram API version, currently `Layer 75`_.
+
+-   **Documented**: Pyrogram API public methods are documented and resemble the well
+    established Telegram Bot API, thus offering a familiar look to Bot developers.
+
+-   **Full API support**: Beside the simple, bot-like methods offered by the Pyrogram API,
+    the library also provides a complete, low-level access to every single Telegram API method.

+Fast Crypto
+===========
+
+Pyrogram's speed can be *dramatically* boosted up by installing TgCrypto_, a high-performance, easy-to-install crypto
+library specifically written in C for Pyrogram [#f1]_. TgCrypto is a replacement for the painfully slow PyAES and
+implements the crypto algorithms MTProto requires, namely AES-IGE and AES-CTR 256 bit.
+
+Installation
+------------
+
+.. code-block:: bash
+
+    $ pip install --upgrade tgcrypto
+
+
+.. note:: Being a C extension for Python, TgCrypto is an optional but *highly recommended* dependency; when TgCrypto
+   is not detected on your system, Pyrogram will automatically fall back to PyAES and will show you a warning.
+
+The reason about being an optional package is that TgCrypto requires some extra system tools in order to be compiled.
+Usually the errors you receive when trying to install TgCrypto are enough to understand what you should do next.
+
+-  **Windows**: Install `Visual C++ 2015 Build Tools <http://landinghub.visualstudio.com/visual-cpp-build-tools>`_.
+
+-  **macOS**: A pop-up will automatically ask you to install the command line developer tools as soon as you issue the
+   installation command.
+
+-  **Linux**: Depending on your distro, install a proper C compiler (``gcc``, ``clang``) and the Python header files
+   (``python3-dev``).
+
+-  **Termux (Android)**: Install ``clang`` and ``python-dev`` packages.
+
+More help on the `Pyrogram group chat <https://t.me/PyrogramChat>`_.

+
+.. [#f1] Although TgCrypto is intended for Pyrogram, it is shipped as a standalone package and can thus be used for
+   other projects too.
