 =====Getting started=====
-Build ChromeDriver by building the 'chromedriver2' target. This will create
-a shared library in the build folder named 'chromedriver2.dll' (win),
-'chromedriver2.so' (mac), or 'libchromedriver2.so' (linux).
+Build ChromeDriver by building the 'chromedriver2_server' target. This will
+create an executable binary in the build folder named 'chromedriver2_server.exe'
+on Windows or 'chromedriver2_server' on Mac and Linux.
 
 Once built, ChromeDriver can be used interactively with python.
-This can be easily done by running python in this directory (or including
-this directory in your PYTHONPATH).
 
+$ export PYTHONPATH=<THIS_DIR>/server:<THIS_DIR>/client
 $ python
+>>> import server
 >>> import chromedriver
->>> driver = chromedriver.ChromeDriver('/path/to/chromedriver2/library')
+>>> cd_server = server.Server('/path/to/chromedriver2_server/executable')
+>>> driver = chromedriver.ChromeDriver(cd_server.GetUrl())
 >>> driver.Load('http://www.google.com')
+>>> driver.Quit()
+>>> cd_server.Kill()
 
 ChromeDriver will use the system installed Chrome by default.
