How do I restore a apple g3 imac bondi blue back it its original factory settings?

I recently purchased an Apple Imac and I was wanting to restore it back to its factory settings but I dont know how its so different from windows im a bit confused, thanks for any help!

You need to use the factory install disks to do a complete factory install. If you don’t have the disks, you can get them from the Apple Store for about $20-30 depending on what system you have.

Pop ‘em in, follow the simple instructions, and you are done!
