There's a lot of useful information about the Things Network in the documentation section of this site.

But there are also some great tutorials about LoRa on Hackster. I've mainly been using a T-Beam and TTN Mapper to test the coverage around the few gateways in my area of Toronto, but a program such as Node-RED is a better choice for real tracking.
This article which was recently published tells you how to use Node-RED to display the location of a tracker node. When I have some spare time, I'm going to use this method to display the location of my T-Beams.

When you go to the link, you will find other interesting articles and projects related to LoRa.
