Question about taking Metro for commute (from Kingsland Park & Ride)

Hey y’all, I’ve been considering taking the Metro Park & Ride going forward to work in downtown.

How is y’all’s experience been with it? Any advice for first-time Metro bus rider?

For payment, I do have a Q Card since I also use the train – is the process as simple as scanning your card like you would do at the train stops?
