+=================
+Installation
+=================
+
+
+Automatic Installation
+^^^^^^^^^^^^^^^^^^^^^^^
+To install Telethon, simply do:
+
+    ``pip install telethon``
+
+If you get something like ``"SyntaxError: invalid syntax"`` or any other error while installing, it's probably because ``pip`` defaults to Python 2, which is not supported. Use ``pip3`` instead.
+
+If you already have the library installed, upgrade with:
+
+    ``pip install --upgrade telethon``.
+
+You can also install the library directly from GitHub or a fork:
+
+   .. code-block:: python
+
+        # pip install git+https://github.com/LonamiWebs/Telethon.git
+        or
+        $ git clone https://github.com/LonamiWebs/Telethon.git
+        $ cd Telethon/
+        # pip install -Ue .
+
+If you don't have root access, simply pass the ``--user`` flag to the pip command.
+
+
+Manual Installation
+^^^^^^^^^^^^^^^^^^^^
+
+1. Install the required ``pyaes`` (`GitHub`__ | `PyPi`__) and ``rsa`` (`GitHub`__ | `PyPi`__) modules:
+
+    ``sudo -H pip install pyaes rsa``
+
+2. Clone Telethon's GitHub repository: ``git clone https://github.com/LonamiWebs/Telethon.git``
+
+3. Enter the cloned repository: ``cd Telethon``
+
+4. Run the code generator: ``python3 setup.py gen_tl``
+
+5. Done!
+
+To generate the documentation, ``cd docs`` and then ``python3 generate.py``.
+
+
+Optional dependencies
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you're using the library under ARM (or even if you aren't),
+you may want to install ``sympy`` through ``pip`` for a substantial speed-up
+when generating the keys required to connect to Telegram
+(you can of course do this on desktop too). See `issue #199`__ for more.
+
+If ``libssl`` is available on your system, it will also be used wherever encryption is needed.
+
+If neither of these are available, a pure Python callback will be used instead,
+so you can still run the library wherever Python is available!
