     function Freeze: boolean;
 
 
+If you call Freeze, the data that is *currently* currently in the client
+is stored into memory. Simba will then target this memory for all further
+finding operations; until *Unfreeze* is called. This can dramatically increase
+speed if you don't care if the image doesn't change. It can be even more
+important if you don't *want* the image to change; if you want to analyze a
+specific frame.
+
+Use like:
+
+.. code-block:: pascal
+    Freeze;
+
+    if findcolors(...) then
+      ...
+
+    Unfreeze
+
+Make sure you never forget to call Unfreeze!
