 ## Overview
 
-What's the big fuss over IT automation?  Well, more than anything, the excitement is about the sorts of things that you _don't_ have to do when automation is on your side.  Things like _not_ having to either copy and paste configuration changes to dozens (maybe hundreds) of different systems or repeat the same click, click, click, click, click-through-the-UI marathon over, and over, and over..._every single time_ there's a need to make a bulk change :rage:.  To automate these sorts of workflows, we need to learn to write some form of automation-specific code.  The **NETCONF** protocol provides a programmatic way to automate the bulk configuration and management of network devices, based on YANG-modeled structured data.

+To automate configuration and management workflows for network devices, we need to learn to write some form of automation-specific code, and the **NETCONF** protocol makes that possible.  **NETCONF** provides a programmatic way to automate the network device workflows based on the predictable data structures found in YANG models.
