Is there a recommended guide for someone

Beyond https://www.zigbee2mqtt.io/guide/getting-started/#prerequisites and the pinned messages here?

• Don't use a CC2531
• Don't use a USB 3.0 port
• Do use a USB extension cable
• Don't use the default channel in Z2M
• Do check what Zigbee channels are quietest (the least WiFi and Zigbee interference) by doing a scan
• Do buy and deploy Zigbee router devices (https://community.home-assistant.io/t/mains-powered-zigbee-devices-that-arent-routers/458500)
• Don't cut the power to Zigbee routers

In particular I'm trying to setup Mosqitto server, configure users, configure HA and then zigbee2mqtt (waiting for the router to arrive)
