-Adds versioning info and enables time travel, if there any resources being used which are [versioned](https://github.com/pemrouz/versioned/issues/1). This is achieved by materializing a list of indices of the individual versioned resources under `ripple.versioned.log`. A change in a versioned resource will create a new list of indicies. Rollbacking to a specfied time simply reregisters the snapshots of all the resources at that time.

+This is achieved by materializing a list of indices of the individual resource versions under `ripple.version.log`. A change in a versioned resource will create a new list of indicies. Rollbacking to a specfied time simply reregisters the snapshots of all the resources at that time.
 
 ```js
-ripple.version()   // get current HEAD
+ripple.version()   // get current time index
 ripple.version(10) // time travel to specified time, returns list of resources reset
 ```
 
 You can also rollback individual resources:
 
 ```js
-ripple.version('foo')     // get current HEAD for resource
+ripple.version('foo')     // get current time index for resource
 ripple.version('foo', 10) // rollback resource, returns resource reset
 ```
 
 Negative numbers are interpreted as relative to the current index:
 
 ```js
-ripple.version(-1) // i.e. undo one step, HEAD~1
+ripple.version(-1) // i.e. undo one step, aka HEAD~1
 ```
