I saw this bed leveling guide online today and thought it may come in handy for someone.

Very good entry level guide. The only issue is it seems to use bed leveling as a way to adjust Z-offset as well, when these should really be two separate calibrations.
The workflow for proper bed leveling is generally using a gcode command to send the machine to a given height on the Z-axis
Ex. G1 Z1 F100 Where G1 is a move command, Z1 dictates 1mm on the Z-axis and F100 dictating the travel speed.
You then disable the steppers and use a shim the thickness of the nozzle distance from the bed (In this example 1mm) at each bed standoff to adjust for a tiny bit of resistance when running the shim under your nozzle.
Carrying out the calibration like dictated in the guide will likely cause no issues with a floating bed (Meaning there are no nonadjustable mounts for the bed on the machine chassis)
However, best practice is generally going to be leveling the bed with a shim and then printing a test print that is exactly one layer tall (For most desktop machines this will be around .2mm) and adjusting the Z-offset (sometimes known as babysteps) using the given rubric. The shim gets you 90% of the way to being dialed, but a good first layer is not always going to be exactly your layer. In most cases ever so slightly too low is a safe bet.
/Unwarranted info dump haha
