 ### `devTools`
 
-A boolean indicating whether `configureStore` should automatically enable support for [the Redux DevTools browser extension](https://github.com/zalmoxisus/redux-devtools-extension).
+If this is a boolean, it will be used to indicate whether `configureStore` should automatically enable support for [the Redux DevTools browser extension](https://github.com/zalmoxisus/redux-devtools-extension).
 
-Defaults to true.
+If it is an object, then the DevTools Extension will be enabled, and the options object will be passed to `composeWithDevtools()`. See
+the DevTools Extension docs for [`EnhancerOptions`](https://github.com/zalmoxisus/redux-devtools-extension/blob/master/docs/API/Arguments.md#windowdevtoolsextensionconfig) for
+a list of the specific options that are available.
+
+Defaults to `true`.
 
 The Redux DevTools Extension recently added [support for showing action stack traces](https://github.com/zalmoxisus/redux-devtools-extension/blob/d4ef75691ad294646f74bca38b973b19850a37cf/docs/Features/Trace.md) that show exactly where each action was dispatched. Capturing the traces can add a bit of overhead, so the DevTools Extension allows users to configure whether action stack traces are captured.
 
-If this parameter is true, then `configureStore` will enable capturing action stack traces in development mode only.
+If the DevTools are enabled by passing `true` or an object, then `configureStore` will default to enabling capturing action stack traces in development mode only.
