+# Donate
+
+If you find this project useful, you can consider donating by using one of the
+channels listed below.

+Companies who donate at least $50/month will be featured as a "Gold Sponsor" in
+the website homepage and on the GitHub repository README. Make contact with
+[@andreynering] with the logo you want to be shown. Suspect businesses
