Create a webpage

[josecelano]

We want to offer the same content on a webpage using GitHub Pages.

We want to use MKDocs for the time being since we are also using it on other projects.

TASKS:

• [x] Setup mkdocs.
• [x] Move content to mkdocs markdown pages. I suppose the whole repo (main branch) could be the MKDocs page. We do not need a docs folder. Setup gh-pages with root.

NOTES:

• I would recommend using one of these two MKDocs themes: gitbook, cinder.

Finally, we use the docs subfolder because we have a lot of MegaLinter configuration stuff that we do not want to mix with the docs.
