 ## Calling Azure services
-Almost each azure services request has three corresponding functions in ```erlazure``` module, the first has minimal set of parameters, the second has additionaly list of ```Options``` and the third has additionaly ```Timeout``` parameter.
+Almost each azure services request has three corresponding functions in ```erlazure``` module, the first has minimal set of parameters, the second has additionaly list of ```Options```.
 
 ```Options``` as the name states is list of options supported by this azure services request, each options is tuple ```{OptionName, OptionValue}``` where ```OptionName``` is atom and ```OptionValue``` can be of any type, option is passed either as a header or as a query string parameter.
 
-```Timeout``` is number of milliseconds to wait for a reply from erlazure, infinity value is not supported. Note, that this is gen_server call timeout and isn't http request timeout (it's set to infinity by default) or azure service request timeout (you can specify it by sending option ```{timeout, _Timeout}```). By default timeout is set to 30 seconds.

 For a list of supported options for each azure service request please consult msdn documentation.
