+A bare-minimum installation of the guest OS. x86_64/amd64 builds are done on
+[Github Actions](https://github.com/greg-hellings/vms/actions) at regular intervals.
+
+If you encounter a bug in the box, please file an issue. If you
+want a newer version of your desired operating system or want to add a distribution to this
+collection, please either file a PR there or open a bug. If you are opening a bug, please provide
+as much information as you can about how an automated installation of your desired distribution
+works.
+
+The goal is to have the bare minimum software to be considered a basic installation of the guest
+OS that is still accessible with Vagrant. Straggling packages or leftover files from the build
+process should be considered as bugs to be filed.
+
+A big shoutout to Github Actions for offering a full VM experience, by default, and generous
+execution times ranging up to 6 hours per task, which allows use of their platform to build
+these boxes with no additional cost to the community.
