+About
+=====
+
+**TgCrypto** is a high-performance, easy-to-install Telegram Crypto Library specifically written in C for Pyrogram [#f1]_ as a
+Python extension. TgCrypto is a replacement for the much slower PyAES and implements the crypto algorithms Telegram requires,
+namely **AES-IGE 256 bit** (used in MTProto v2.0) and **AES-CTR 256 bit** (used for CDN encrypted files).
+
+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 in 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.
+The errors you receive when trying to install TgCrypto are system dependent, but also descriptive 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.
+-  **Linux**: Install a proper C compiler (``gcc``, ``clang``) and the Python header files (``python3-dev``).
+-  **Termux (Android)**: Install ``clang`` and ``python-dev`` packages.
+
+Contribution
+============
+
+**You are very welcome to contribute** by either submitting pull requests or
+reporting issues/bugs as well as suggesting best practices, ideas, enhancements
+on both code and documentation. Any help is appreciated!
