Things you need

You must have a DMR ID before you can access any digital network. You can go to RadioID to request for your DMR ID. Once you get your DMR ID, you have to register in Brandmeister Network. Once you have created your account, go to Services -> Selfcare. Set the Brand = Motorola, then enable Hotspot Security, put in your Hotspot password then click on save.

I am assuming that you have a wifi router that you can connect to, and a computer that can connect to that wifi. You also need a way to write to a Micro-SD card. These are the bare minimum that you need to get your hotspot going.
1. Lonestar MMDVM Duplex Hotspot Board
2. Pi Zero WH
3. Pi Zero Power Supply
4. Micro SD Card at least 8GB

Let's get started!

1. Download softare from Pi-Star Website. I got the file Pi-Star_RPi_V4.1.4_08-Feb-2021.zip. Once downloaded, extract all files to a directory of your choice.
   
2. If you don't have a software to burn image to your MicroSD card, download balenaEtcher and install.
   
3. Insert your MicroSD card to your card reader and burn the image (Pi-Star_RPi_V4.1.4_08-Feb-2021.img) you downloaded and unzipped from PiStar to your MicroSD using balenaEtcher.
   
4. Ok, now stop here! You don't need to create a file called wpa_supplicant.conf to be able to setup your Pi wifi.
5. Eject your MicroSD card from your computer. Assemble your Pi Zero and Lonestar MMDVM, connect the antenna then slide the MicroSD into the slot on the Pi Zero. Connect your power supply and start em up.
   
6. When Pi detects that it's not connected to any network, it will launch itself in to AP mode (Access Point). It means that you can connect to it like how you connect to your wifi router. From your computer connect to your Pi's AP. When you search for a wifi network from your computer, you will see Pi-Star and connect to it. The login is pi-star and the password is raspberry. Once in, open a browser then go to http://pi-star then scroll down until you see Wireless Configuration. Click on Configure WiFi then configure your wifi connection to your wifi router.
   
7. Once you see that your Pi is connected to your wifi network, take note of the IP address, then reconnect your computer to your wifi network. Open a browser then connect to your Pi using Http://pi-star or you can use the IP address.
8. To get you going, configure your hotspot this way. Just put in your own information specially your own DMR ID. I have to click on Apply Changes on each and every section when I was doing this. I'm not sure if you can edit all sections and hit just any Apply Changes button.
   
   
   
9. Now that we have your Hotspot running, let us now configure your DMR radio.
