+
+What The Overviewer is not
+--------------------------
+Full disclosure disclaimers of what The Overviewer is *not*.
+
+* It does not run fast. Because of the high level of detail, initial renders of
+  a world can take some time. Expect minutes for medium worlds, hours for large
+  to huge worlds. Subsequent renders are *much* faster due to the caching.
+
+  Also note that speed is improving all the time. We continually make efficiency
+  improvements to The Overviewer. Besides, for the level of detail provided,
+  our users consider it worth the time!
+
+* Overviewer is not targeted at end users. We mainly see Overviewer fitting in
+  best with server operators, rendering their server's map for all users to
+  view.
+
+  You are welcome to use Overviewer for your single player worlds, and it will
+  work just fine. However, since the only interface is currently command line
+  based, you will need to know a bit about the command line in order to operate
+  The Overviewer.
