Changed pooly to look for an environment variable to tell it where the

pooly.conf file is located.  It was looking for it in its own priv
directory which did not allow it to be portable between applications.

+* Changed application to look for an environment variable to tell it where the pooly.conf file is located.  This should improve portability when included in other applications.

 #### 8/14/2011
 * Added support for multiple pools
 * Added support for default configuration parameters but allow a pool to override a parameter
-* Added support for generic OTP compliant pools 
+* Added support for generic OTP compliant pools
 
 ## Quick Start
 
 1.  Create a pooly.conf configuration file in the priv directory
 2.  Configure one or more pools in the configuration file
-3.  Start up erlang
+3.  Create an app config file for your application which includes:
+```
+    [{pooly, [{config_file, LocationOfFile}]}].
+
+    e.g. [{pooly, [{config_file, "priv/pooly.conf"}]}].
+    This will allow pooly to use your application's priv directory as opposed to its own.
+```
+
+4.  Start up erlang using the -config directive passing it the name of your config file.  For example, if your application config file is named, myApp.config, you would type: erl -config myApp
 
 ```
 > application:start(pooly).
