 ## Features
 
+Vert.x `DataLoader` is a feature-complete port of the Facebook reference implementation with [one major difference](#manual-dispatching). These features are:
+
 - Simple, intuitive API, using generics and fluent coding
 - Define batch load function with lambda expression
 - Schedule a load request in queue for batching
 - Add load requests from anywhere in code
 - Request returns [`Future<V>`](http://vertx.io/docs/apidocs/io/vertx/core/Future.html) of requested value
 - Can create multiple requests at once, returns [`CompositeFuture`](http://vertx.io/docs/apidocs/io/vertx/core/CompositeFuture.html)
 - Caches load requests, so data is only fetched once
-- Can clear individual cache keys, so data is fetched on next load request dispatch
+- Can clear individual cache keys, so data is fetched on next batch queue dispatch
 - Can prime the cache with key/values, to avoid data being fetched needlessly
 - Can configure cache key function with lambda expression to extract cache key from complex data loader key types
-- Dispatch load request queue when batch is prepared, returns `CompositeFuture`
-- Individual batch futures complete as batch is processed
+- Dispatch load request queue after batch is prepared, also returns [`CompositeFuture`](http://vertx.io/docs/apidocs/io/vertx/core/CompositeFuture.html)
+- Individual batch futures complete / resolve as batch is processed
 - `CompositeFuture`s results are ordered according to insertion order of load requests
 - Deals with partial errors when a batch future fails
 - Can disable batching and/or caching in configuration
 - Can supply your own [`CacheMap<K, V>`](https://github.com/engagingspaces/vertx-dataloader/blob/master/src/main/java/io/engagingspaces/vertx/dataloader/CacheMap.java) implementations
 - Has very high test coverage (see [Acknowledgements](#acknowlegdements))
