Instead of going into detail, the better way would be to download the service manual and review the procedure at your leisure.
It's not difficult at all. It may be messy if the coolant splashes everywhere when the hose is removed, but otherwise straight forward.
As for coolant, you should use a silicate-free coolant as silicates can wear water pump bearings and seals.
Honda OEM coolant, water wetter, engine ice, etc. are typically used.
Mix the coolant 50/50 (if not already pre-mixed) with distilled or deionized water (NOT tap water). Fill the system and purge.
While you're at it, check the condition of your fan(s) bearings by giving them a spin.
Often when they will start to squeak when getting old. If they don't easily spin, then replace the fan motors.
