 ## Advanced Usage
 
-### Saving Wrangler Command Output to a File
+### Using Wrangler Command Output in Subsequent Steps
 
-More advanced workflows may need to parse the resulting output of Wrangler commands. To do this, you can use the `outputFile` option to save the output of the command to a file. This file will be available to subsequent steps in the workflow. The format of this file is JSON so that it can be easily parsed by other steps.
+More advanced workflows may need to parse the resulting output of Wrangler commands. To do this, you can use the `command-output` output variable in subsequent steps. For example, if you want to print the output of the Wrangler command, you can do the following:
