[!NOTE] If this is your first time using the MkDocs plugin feature, you should know that MkDocs includes a default plugin named search. If you want to keep the search feature, you need to add the search plugin back to the plugins list.

How it works

1. Copy GLightbox script file into site/assets/javascripts/ directory and CSS file into site/assets/stylesheets/ directory
2. Import GLightbox script and CSS file and add javascript code on each page excluded disabled pages
3. Search all image tags and warp with an anchor tag for GLightbox excluded images with skip class or already warped with an anchor tag
