 v1.x vs v2.x
 ------------
 
-The old v1 used `ws` which makes it usable when clustering node processes without using `cluster`.
+The [old v1](https://github.com/coolaj86/cluster-store/tree/v1.x)

-If you need that functionaliy, use it.
+If you need that functionaliy, use v1 instead of v2.
 
 Usage
 =====
 
+In its simplest form, you use this module nearly exactly the way you would
+the any other storage module, with the exception that you must wait for
+the inter-process initialization to complete.
+
+When not using any of the options the usage is the same for the master and the worker:
+
+```javascript
+require('cluster-store').create().then(function (store) {
+  // initialization is now complete
+  store.set('foo', 'bar');
+});
+```
+
 ### standalone (non-cluster)
 --------------
 
-The usage is exactly the same as **master**, no changes necessary.
+There is no disadvantage to using this module standalone.
+The additional overhead of inter-process communication is only added when
+a worker is added.
+
+As such, the standalone usage is identical to usage in master process, as seen below.
 
 ### master
 
-In the **master**/**standalone** process you will create the real store instance
-and then in the you must pass each worker via `addWorker()` so that it signals
-the worker to create its own rpc-wrapped instance.
+In the **master** process you will create the real store instance.
+
+If you need to manually specify which worker will be enabled for this funcitonality
+you must set `addOnFork` to `false` and call `addWorker()` manually.
