-The actual program only has two buttons, "Next card" and "Reveal card",
-which should be obvious. The number of times the card was viewed is
-saved in `config.json` and a random card from the cards that have been
-viewed the least is displayed each time.
+The actual program only has four buttons:
+
+- "Next card" goes to the next card and increases the view count of the
+  currently viewed card (but only if the back was revealed).
+- "Next (no view increase)" does the same but never increases the view count.
+- "Reveal back" reveals the back of the card.
+- "Reload images" reloads the images from the cache (useful when editing
+  the LaTeX files since you can regenerate the cache and then just
+  reload images).
+
+The number of times the card was viewed is saved in `config.json`.
+The "next" buttons choose a random card from the cards that have been
+viewed the least each time.
