Can someone tell me how to format reinstall 10.8

[Jason Garza]

I am going to be selling my iMac to night that is currently running 10.8 ( yes I bought it from the App Store ) My questions are how do I do a fresh install without a disk and is it transferable to a new owner, since I bought it with my apple id ( meaning will he need my apple Id to get updates ) I searched first, but only could find results on new installs. Thanks

Hold Command-R at start up or hold the Option key at startup (until you see boot screen) and choose recovery.
Both option will get you into recovery where you can do a clean install of OS X, but, be aware, it's a 4-5 GB download.

Thank you for the quick response.
