+### Rake tasks
+
+Each driver has its own set of `rake` tasks that you can call once before 
+executing the tests.  These are especially useful if you're running tests
+in parallel and want to avoid performing an update check per thread.
+
+```bash
+$ bundle exec rake -T
+rake webdrivers:chromedriver:remove           # Force remove chromedriver
+rake webdrivers:chromedriver:update[version]  # Remove and download updated chromedriver if necessary
+rake webdrivers:chromedriver:version          # Print current chromedriver version
+rake webdrivers:geckodriver:remove            # Force remove geckodriver
+rake webdrivers:geckodriver:update[version]   # Remove and download updated geckodriver if necessary
+rake webdrivers:geckodriver:version           # Print current geckodriver version
+rake webdrivers:iedriver:remove               # Force remove IEDriverServer
+rake webdrivers:iedriver:update[version]      # Remove and download updated IEDriverServer if necessary
+rake webdrivers:iedriver:version              # Print current IEDriverServer version
+```
+
+These tasks respect the `WD_INSTALL_DIR` and `WD_CACHE_TIME` environment
+variables which can also be passed through the `rake` command:
+
+```bash
+$ bundle exec rake webdrivers:chromedriver:update[2.46] webdrivers:geckodriver:update[0.24.0] WD_CACHE_TIME=86_400 WD_INSTALL_DIR='my_dir'
+2019-05-20 19:03:01 INFO Webdrivers Updated to chromedriver 2.46.628388
+2019-05-20 19:03:04 INFO Webdrivers Updated to geckodriver 0.24.0
+```
+
+Please note that these tasks do not use any of the configurations from your
+project (code) and only respect the `ENV` variables and the version (optional)
+passed to the `rake` task.
