Wiring Questions

Hello! I'm new to Raspberry Pi's and electrical stuff like this in general. I followed the instructions and purchased a Solid State 8 Channel Relay and a WS2811 LED Strip. I have no idea where to begin with wiring this thing up to even get the lights to turn on, much less flash to music lol.

I've looked through the subreddit but it seems that a base knowledge of this stuff is implied in most posts/comments. Does anybody have a link to a wiring guide or a video to show I'm supposed to physically connect the RabPI to the Relay and the LED Strip.

Thanks!
