Add an FAQ question to the Readme

Fixes #128.

I think that more questions will need to be answered about this script
in the future. Therefore, I decided to add a section dedicated to these
questions so more can be easily added in the future, instead of just
being scattered as Notes in the Readme.

+## FAQ
+Below, a list of answers to frequently asked questions about Auto-Southwest Check-In can be found. If you believe any more
+questions should be added to this list, please submit a [Discussion][7] or [Pull Request][8] so the addition can be made.
+
+### Do I Need to Set up a Different Instance of the Script for Each Passenger on My Reservation?
+This script will check the entire party in under the same reservation, so there is no need to create more than one instance
+of the script per reservation.
+
+However, this is not the case if you have a companion attached to your reservation. See the next question for information on
+checking in a companion.
+
+### Will This Script Also Check in the Companion Attached to My Reservation?
+Unfortunately, this is not possible due to how Southwest's companion system works. To ensure your companion is also checked in,
+you can set up their reservation or account separately in the configuration file.
+
+### While Attempting to Run This Script, I Get a [SSL: CERTIFICATE_VERIFY_FAILED] Error. How Can I Fix It?
+If you are on MacOS, this most likely occurred because your Python installation does not have any root certificates. To install
+these certificates, follow the directions found at [this Stack Overflow question][9].
