[!DANGER|style:flat] If you don't have the willingness to tinker and learn... TURN BACK!.
Tasmota is not a commercial product and support is limited. You have to be willing to research and debug potential problems yourself.
To install Tasmota on your device first prepare some tools and software from the prerequisites list.
Tip
If your device works with Tuya Smart or Smart Life app it may be possible to flash it with Tuya-Convert without disassembly or soldering and skip directly to Initial Configuration.
