+**Disclaimer** v2.x.x and v3 are for Cycle Diversity!
 If you are still using @cycle/core please continue to use v1.x.x
 
 ## Installation
 
 Using [npm](https://www.npmjs.com/):
 
-    $ npm install cyclic-router
+    $ npm install --save cyclic-router
+
+Version 3 requires users to inject the route matcher.  We'll use `switch-path` for our examples but other
+matching libraries could be adapted to be used here:
+
+    $ npm install --save switch-path
+
+Note: Version 2 and below use `switch-path` for the route matcher always and the above library install is not necesssary/done implicitly.
 
 Then with a module bundler like [browserify](http://browserify.org/), use as you would anything else:

 ### Route Parameters
 
-You can pass route parameters to your component by adding them to the component sources.
+This behavior changes based on the injected route matcher.  In the case of `switch-path`, you can pass route parameters to your component by adding them to the component sources.
