Installation
============
Using PIP
---------
Django MarkdownX may be installed directly using Python Package Index (PyPi):

.. code-block:: bash

    python3 -m pip install django-markdownx


From the source
---------------
Should you wish to download and install it using the source code, you can do as follows:

Note
    Make sure you have activated your virtual environment if you're using one.

We start off by downloading the source code from GitHub and navigate to the downloaded directory:

.. code-block:: bash

     git clone https://github.com/adi-/django-markdownx.git
     cd django-markdownx/


Install the package. You can replace ``python3`` with ``python`` or any of |Supported_versions_of_Python| if
you have multiple versions installed on your machine:

.. code-block:: bash

   python3 setup.py install
