+## Description for Poets
+
Once you summon the Hydra through the prefixed binding (the body + any one head), all heads can be
called in succession with only a short extension.
command. This makes the Hydra very seamless, it's like a minor mode that disables itself
auto-magically.
+## Description for Pragmatics
+
+Imagine that you have bound <kbd>C-c j</kbd> and <kbd>C-c k</kbd> in your
+config. You want to call <kbd>C-c j</kbd> and <kbd>C-c k</kbd> in some
+(arbitrary) sequence. Hydra allows you to:
+
+- Bind your functions in a way that pressing <kbd>C-c jjkk3j5k</kbd> is
+equivalent to pressing <kbd>C-c j C-c j C-c k C-c k M-3 C-c j M-5 C-c
+k</kbd>. Any key other than <kbd>j</kbd> or <kbd>k</kbd> exits this state.
+
+- Assign a custom hint to this group of functions, so that you know immediately
+after pressing <kbd>C-c</kbd> that you can follow up with <kbd>j</kbd> or
+<kbd>k</kbd>.
+
