# OpenWhisk Debugger
-This project currently supports debugging OpenWhisk actions written in NodeJS. The debugger will arrange things so that the actions you wish to debug will be offloaded from the main OpenWhisk servers and instead run on your laptop. You can then, from within the debugger, inspect and modify values, and even modify code.
+This project currently supports debugging OpenWhisk actions written in NodeJS. The debugger will arrange things so that the actions you wish to debug will be offloaded from the main OpenWhisk servers and instead run on your laptop. You can then, from within the debugger, inspect and modify values, and even modify code. At this point in time, the modifications will be one-time only. In the near future, we hope to add the ability to push any code updates back to OpenWhisk.

+The debugger currently supports inspecting individual actions and actions within sequences. In the near future, we hope to add the ability to debug actions run from rules as well.
For now, you must have [NodeJS](https://nodejs.org) installed on your computer in order to use the debugger.
