DISCLAIMER="This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations. This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected. Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.
