+Caching
+=======
+
+When your application runs slow, throw some caches in.  Well, at least
+it's the easiest way to speed up things.  What does a cache do?  Say you
+have a function that takes some time to complete but the results would
+still be good enough if they were 5 minutes old.  So then the idea is that
+you actually put the result of that calculation into a cache for some
+time.
+
+Flask itself does not provide caching for you, but `Flask-Caching`_, an
+extension for Flask does. Flask-Caching supports various backends, and it is
+even possible to develop your own caching backend.
