+GETTING STARTED --
+
+Just click on startpage:// in the top left corner and enter
+a gopher:// or gemini:// URL you'd like to visit.
+
+Here's a good starting point: gopher://gopher.floodgap.com/
+
+
+WHAT'S GOPHER? --
+
+Gopher is an internet protocol that was developed in 1991.
+It's a very simple protocol that, unlike the World Wide
+Web, is very text-focused and doesn't support technologies
+like CSS, JavaScript or even cookies.

+
+WHAT ABOUT GEMINI? --
+
+Gemini is a new internet protocol that is still in the
+process of being developed. Its purpose is to be an
+alternative to both Gopher and the WWW by being more
+powerful than Gopher, but lighter than the WWW.
