AC Removal Help

Hey Ya'll
Need some help/info on how to completely remove AC system.
Most of this question is in regards to the Freon. I know the system is under pressure, and want to do it safely.
How and where do I start to make the system safe to unbolt ?

Want to get everything out of the way i can start cleaning up the engine bay.
May reinstall, may not.
Thanks guys/gals.
