+methods, you can either greatly decrease your time spent studying, or
+greatly increase the amount you learn.
+
+Anyone who needs to remember things in their daily life can benefit
+from Anki.  Since it is content-agnostic and supports images, audio,
+videos and scientific markup (via LaTeX), the possibilities are
+endless.  For example:
+@itemize
+@item Learning a language
+@item Studying for medical and law exams
+@item Memorizing people's names and faces
+@item Brushing up on geography
+@item Mastering long poems
+@item Even practicing guitar chords!
