Say thanks with a small donation

Every dollar goes toward hosting, software, and new guides.

Where does the money go?

  • Hosting and infrastructure: the ongoing costs of keeping the site online and fast.
  • Software: open-source tools we use to build and maintain the site.
  • New guides: a modest "coffee" for the volunteer writers.

That's it. No office, no employees, no marketing budget. If a month goes by and we've collected a little extra, we put it toward commissioning illustrations for the next round of guides.

Our promise

This site stays free forever — even if you never donate a penny. No content is ever gated behind a paywall, no "Pro" version, no email sign-up required. Donations are purely a "thank you" from readers who found the site useful.
