What is the C:/Users/<user>/.chefdk directory for?

To date we’ve been using chef solo with all necessary information to run the chef-client passed as command line arguments. We’re trying to adopt a workflow leveraging Chef Server now and I’m working through understanding bootstrapping and the various means for configuring knife and chef-client, etc. We’re using Windows 10 as our workstation platform. Somewhere in my playing I wound up with a C:/Users//.chefdk directory as a sibling to C:/Users//.chef. Does this directory play any role in the Chef ecosystem? I thought I found some doc once that talked about the need for this, but I’m not finding it now.

It’s entirely possible I created this directory myself in the past out of ignorance.

That is your chefdk home directory where gems that you install will live. See the chef-dk readme here.
