+You will now be in the `wsdk` REPL. Issue `help` to see the list of available commands.
 
 Note: the first time you launch `wskdb`, you will experience a ~60 second delay, as the debugger finishes up the installation. This includes pulling in the package dependencies supported by OpenWhisk. These dependencies will allow you to debug actions that require one or more of the [packages supported by OpenWhisk](https://dev-console.stage1.ng.bluemix.net/docs/openwhisk/openwhisk_reference.html#openwhisk_ref_javascript). If you have already initialized the debugger, you can always choose to reinitialize it via `wskdb --reset`; this will reinstall the dependencies.

First, the user can change the action's source code by clicking on the code and editing it. Note that currently the user can only edit the code before the debugger entering the main action function. In this example, I change the code to say "hi" instead of "hello". I then save the change and press the "go" button to enter the main function. The second thing the user can do with the debugger is to inspect parameters and change their values using the "Local" tab in the right panel.
