Help/teach me to do the raids

Hello everyone! I'm new to raiding and would greatly appreciate it if someone could help/teach me to do them. I have actually done Crota's End on normal once, but it was with a team that knew what they were doing and we glitched the bridge section, so I don't really want to count it. Did not learn much from it either. I have also tried Vault of Glass (hard I think, but not sure) with a bunch of randoms, but I came in at the Gorgons section and made it to Atheon but after a few tries I had to leave. Never had the chance to try it again since then. I play on [b]PS4 [/b]and my PSN is [b]Cylph[/b], I mainly play Defender Titan but have all classes with fully upgraded subclasses. I'm not an excellent FPS player so you probably need some patience when helping me, but I think I can follow directions pretty well. See you there.
