Build and host Locally?

Hi all, I am new to OHIF and new to web programming, I am able to follow the “Getting started” instructions to “yarn run dev” and launch the OHIF viewer on my localhost:3000

Now I am wondering how can I make the running on my localhost:3000, so I can browse and open my local disk Dicom images? I guess this is easier than setting up a PACS server on my local machine and then connect to this PACS server.

My goal is to learn OHIF and ultimately develop something useful on top of it with my Dicom images, but I need help to take my “baby steps” first…
