+tl;dr: To see all prompt styles in the configuration wizard, install [the recommended font](
+  #meslo-nerd-font-patched-for-powerlevel10k) and resize your terminal to at least 80 columns by 25
+lines prior to running `p10k configure`.
+
+The first few questions in the configuration wizard are meant to assess the capabilities of the
+terminal font. If your answers indicate that some glyphs don't render correctly, configuration
+wizard won't offer prompt styles that use them. If you'd like to see all prompt styles, install
+[the recommended font](#meslo-nerd-font-patched-for-powerlevel10k).
+
+The minimum screen size at which configuration wizard can function is 55 columns by 21 lines.
+However, not all prompt styles are offered at such small screen size as there is simply not enough
+space to present them. Resize your terminal to at least 80 columns by 25 lines prior to running
+`p10k configure` to see all prompt styles.
