+## Supported browsers
+
+### Tests with Protractor test suite (v 4.0.13)
+
+The following are the supported browsers / drivers based on running the
+Protractor test suite. Since the test suite checks only firefox and chrome,
+these are the only browsers reported.

+### Current supported browsers / drivers

+| ------------------- | ------- | ------------ | ------ |

+## Driver providers
+
+There are a couple cases where Protractor launches downloaded binaries
+(from webdriver-manager) without specifying which version to use:
+
+- local driver providers - when no `seleniumAddress`, `directConnect`, saucelabs
+  or browser stack configuration is set
+- direct connect - when setting `directConnect` to true
+
+Protractor knows which downloaded binaries to use based on the
+`update-config.json`. The `update-config.json` is written during the `update`
+command and provides the path to the current downloaded version and a list of
+all the binaries previously downloaded.
+
+During the launch of either local driver provider or direct connect, Protractor
+will launch the last downloaded binary.
