Updated debugging section

* Moved Sayid debugger to its own page.  Need to add more on using Sayid with
  Spacemacs.

 # Debugging
 
-[Sayid](http://bpiel.github.io/sayid/), pronounced "siy EED", is an omniscient debugger and profiler for Clojure.
+I would argue that debugging is less critical in Clojure as you have the REPL and mostly pure functions (hopefully), so its easy to evaluate parts of your code to see the results.
 
-Sayid works by intercepting and recording the inputs and outputs of functions. It can even record function calls that occur inside of functions. The user can select which functions to trace. Functions can be selected individually or by namespace. The recorded data can be displayed, queried and profiled.
+Spacemacs clojure layer also provides an inspector and a debugger.
 
-Sayid currently has three components:
-- core and its supporting namespaces
-- nREPL middleware
-- an emacs-cider nREPL client
+* cider-inspector
+* sayid debugger

-|-------------|--------------------------------|
-| `SPC m d b` | instrument expression at point |
-| `SPC m d e` | display last stacktrace        |
-| `SPC m d r` | reload namespaces             |
-| `SPC m d v` | inspect expression at point    |
