Heya, ping me sometime if you want a little hand-holding to get you started. Check System Information > Display to see if you have an NVidia video board. If you don't have one that can run SD locally, We can look at some online generators.

It really isn't hard. Honest. The issues you read here are most technical ones that apply to specific issues when using a local setup. If you generate online, many of those issues are resolved or won't occur because the operators have pre-configured to system to avoid it.

Take care, stay safe.
