 * Added support for automatic datafile management via `HttpProjectConfigManager` for framework 4.0 or above:
   * The [`HttpProjectConfigManager`](https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/Config/HttpProjectConfigManager.cs) is an implementation of the abstract
       [`PollingProjectConfigManager`](https://github.com/optimizely/csharp-sdk/blob/master/OptimizelySDK/Config/PollingProjectConfigManager.cs) class.
-    - Users must first build the `HttpProjectConfigManager` with an SDK key and then and provide that instance to the `Optimizely`.
-    - An initial datafile can be provided to the `HttpProjectConfigManager` to bootstrap before making http requests for the hosted datafile.
+    - Users must first build the `HttpProjectConfigManager` with an SDK key and then and provide that instance to the `Optimizely` instance.
+    - An initial datafile can be provided to the `HttpProjectConfigManager` to bootstrap before making HTTP requests for the hosted datafile.
     - Requests for the datafile are made in a separate thread and are scheduled with fixed delay.
     - Configuration updates can be subscribed to via the NotificationCenter built with the `HttpProjectConfigManager`.
     - `Optimizely` instance must be disposed after the use or `HttpProjectConfigManager` must be disposed after the use to release resources.
