Sphinx is a python documentation generating tool (that can be used for other languages) that uses a markup language called "reStructuredText" to convert files into HTML webpages and other format types (like PDF and LaTex).
To make html locally you need to do the following.
git clone git@github.com:panta-123/hcana_container_doc.git
cd into the cloned folder.
Setup the virtual environment and activate it:
python3 -m venv .env
source .env/bin/activate
Install using (only should be done once.)
pip install sphinx sphinx-rtd-theme sphinx-copybutton
Now build the doc
make html
