Dead link in the intro of the Templates part
In 4-templates/1-Intro.ipynb
, the additional link about friends with templates is dead.
It should be changed from https://web.mst.edu/~nmjxv3/articles/templates.html
(current URL) to either https://web.mst.edu/_disabled/nmjxv3/articles/templates.html
or (probably safer?) the last archived version https://web.archive.org/web/20211003194958/https://web.mst.edu/~nmjxv3/articles/templates.html
