Configuring DMR is not all that difficult to do. like I said before if you have the technical ability to learn ham radio and get your ticket you can learn DMR

Here are some basic skills you will need to have or learn to properly configure your hotspot and program your radio yourself,
 you do not need a doctorate in computer science

Windows PC for your code plug
Some Linux for your MMDVM pi-star hotspot, although not required

---

A positive "can do" attitude and some patience

Reliable Internet access WiFi or a LAN network for the hotspot, knowledge, connecting and disconnecting wireless devices to your home network, logging into your network router

Basic computing skills, using a web browser, saving downloaded files, file system organization and access, creating and saving files using Excel or other spreadsheet programs for you code plug CSV files

Downloading and Installing software and cable drivers, run CPS software to program the radio

(Not always the case) Accessing and configuring your computers com ports you may need to use "device manager" (not always required)

You need to know how to access your cellphones hotspot network data if you want to use your hotspot in the mobile , creating an access point and simple passkey

Pick a DMR network or networks and gather a talk group list for them

Know your radio and it's abilities (read the manual)

Once you get these basics down and are able to at least function on DMR all the rest will come with time and continued use
Have fun, explore, it's okay to make mistakes remember ham radio is a hobby not professional radio
