 Now, execute your test by passing env variable NAKAL_MODE=build to build the baseline images. All baseline images will be stored in baseline_images folder in current directory
 
 once baseline is built, next execution onwards, start using environment variable NAKAL_MODE=compare to compare against baseline.
 any difference will be put in the same directory with image file named "current_screen_name_diff.png"
 
-## Important
+If You want to organize baseline nicely, you can even specify sub-paths in #nakal_execute like this:
 
-* This works best when your tests are running against mocked data
-* If test data keeps changing for each test, use diff_metric (output of nakal_execute method above) to determine if the change is acceptable.
+	diff_metric = nakal_execute("feature/sub_feature/current_screen_name")
 
 For setting custom directory, use:  
 
 	Nakal.directory= "<desired_directory>"
 	Nakal.device_name = "nexus7"
 
-For cropping the notification bar OR scroll bar, create a config/nakal.yml file in execution directory

-## ToDo  
-1. Put a logic to wait for screen to load until it is matching the baseline. Timeout after certain time and fail.
+## Note
+1. There is implicit wait of 30 sec until current screen matches baseline. This timeout can be changed by setting:  
+	
+		Nakal.timeout = new_timeout_value
