Up-to-date installation guide for Raspberry Pi?

I’ve come across a few Raspberry Pi installation guides on the internet. However, none of them were written recently (except one which was in another language). I’ve noticed that all the guides I found were created using a writefreely website and so I’m hoping one of you guys have a relevant guide available! Alternatively, if anyone has recently installed writefreely on a Raspberry Pi, could you please link me the guide you used?
