**The About page is empty for now** but would be great to have some information
about Shoes here.

Additional Note: The **texts for the page are not that great.** Partly because
I had English as a second language in school :) So improvements are welcome.
Also: The background images (and header of tutorials page) are taken from
Nobody Knows Shoes, I thought it would be nice to have a bit of *_why* on the
site. :heart:
