Where do I start? How do I use this thing? Where are tutorials?

IoT Modules

My employer has made a custom board with an HL7812 on it, intending to use it for MQTT and IOT applications. I need to learn how to control it. I have the AT Command reference manual, but alone, it’s meaningless. I’ve seen the Open AT documentation. That’s not what I need. The firmware will be running on an MCU, not on the HL7812. Where is information explaining what I need to do? And why is there no “Getting Started” document jumping out at me on the “Welcome To The Source” page?
