-You can:
-* Easily check the state of each coroutine.
+With the coroutine debugger, you can:
+* Check the state of each coroutine.
 * See the values of local and captured variables for both running and suspended coroutines.
 * See a full coroutine creation stack, as well as a call stack inside the coroutine. The stack includes all frames with 
 variable values, even those that would be lost during standard debugging.
+* Get a full report that contains the state of each coroutine and its stack. To obtain it, right-click inside the **Coroutines** tab, and then click **Get Coroutines Dump**.
 
-If you need a full report containing the state of each coroutine and its stack, right-click inside the **Coroutines** tab, and then
-click **Get Coroutines Dump**.
+To start coroutine debugging, you just need to set breakpoints and run the application in debug mode.
