Create virtual environment

You may want to use a separate virtual environment for your demo project. Skip this step if you prefer to work in your current environment, just make sure you have Sphinx installed.

I am using Miniconda to create a demo environment and run all commands, but you can use Python venv and pip if you want.

To create a demo environment in Miniconda:

1. Create a virtual environment named intl:

   conda create --name intl python
   

2. Activate this environment:

   conda activate intl
   

3. Install Sphinx in the new environment:

   pip install sphinx
   

   Alternatively, you can download requirements.txt that lists all the packages installed in my intl environment, and then run:

   pip install -r requirements.txt
   

   In this case, sphinx-intl is installed as well.
