Hi there 👋. Please note that only the code and documentation of this
site are MIT licensed. But my logo and the combination of typography,
colors, and layout making up my brand identity are not. Likewise, if
you know how to remove this banner you also should be able to remove
my Typekit code and Analytics code from your published site.
