Help with getting Homegroup to work?

My desktop has a MS account and my portable is a local account. I have set my desktop with a Homegroup PW and have chosen what I would like to share with my portable (following the forum's instructional video). However, I do not know how to proceed from here in order to get the two computers to communicate. Do I have to go to my portable and enter the PW, and if so, how is this done? If not, what do I have to do? Also, I would imagine that once things are set up right, in order to communicate, both computers would have to be on??? Thanks.

Go to your portable > open File Explorer > left side, click Homegroup > click Join Homegroup > select what you want to share etc etc.......... >Enter password

Wow! That should be easy, and it was. Now have easy access between both computers. Thanks.
