+
+## Define Hydra heads that don't show up in the hint at all
+
+This can be done by setting the head's hint explicitly to `nil`, instead of
the usual string.
+
+## Use a dedicated window for Hydra hints
+
+Since version `0.10.0`, setting `hydra-lv` to `t` (the default setting) will
make it use a dedicated
+window right above the Echo Area for hints. This has the advantage that you
can immediately see
+any `message` output from the functions that you call, since Hydra no longer
uses `message` to display
+the hint. You can still have the old behavior by setting `hydra-lv` to `nil`.

+## Color table

+ | pink | red | Allow and Continue | Continue |
+ | red | red | Allow and Quit | Continue |
+ | blue | blue | Allow and Quit | Quit |
+
+## Color to toggle correspondence
+
+By popular demand, an alternative syntax has been implemented that translates
to colors without
+using them in the syntax. `:exit` can be used both in body (heads will
inherit) and in heads
+(possible to override body). `:exit` is nil by default, corresponding to `red`
head; you don't need
+to set it explicitly to nil. `:foreign-keys` can be used only in body and can
be either nil (default),
+`warn` or `run`.
