-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.
