Thanks @dsrishyla ! Let's keep this PR open until the content is there.

A tip on the image and video. I don't think we need an image since it is just a flash of light ;). I can add a video of PLR to my Vimeo account (and while I'm at it, maybe I can share that folder with you can give you admin rights to it).

FYI I think you need to set your username and email in git so that you are properly credited for your Pr's (you were not credited for your last PR).

In your terminal, while in the Q1K-neuroimaging directory run each of the lines below:

git config user.name "Your Name"
git config user.email "your email"

Putting your actual name and email in.

Since this task has no conditions, we probably don't need this. You can just change this section name to "Overview" and describe the task.

We probably don't need this section. Can just describe the task in the Overview section.

Probably don't need this image directive or the figure directive below it.
