I feel like I'm so close, but I'm missing something important

Here's what I've done:
1. Clicked the 'Share Workbook' button on the Review tab
2. Checked the box that says 'Allow changes changes by more than one user at the same time'
3. Selected the settings I want

...now what...

If I put the file on a jump drive and put it on multiple computers that use the same internet will they all be linked?
This seems to easy, and I would test it right now, but I don't have a jump drive.

Thanks in advance!!
