-#### Initialization
 Create the Optimizely client, for example:
 
 ```php
 $optimizely = new Optimizely(<<DATAFILE>>);
 ```
 
-Or you may also use OptimizelyFactory method to create an optimizely client using your SDK key, an optional fallback datafile and an optional datafile access token. Using this method internally creates an HTTPProjectConfigManager. See [HTTPProjectConfigManager](#http_config_manager) for further detail.
