MBA 13" mid2011 format

[thornguy]

I'm looking at giving my wife my MBA and I'd like to wipe it out so its "fresh" like a new one would be.
I understand I can get to OS Utilities with reboot cmd-r
I and do a "reinstall Mac OS X". Do I need to erase the disk first?
Right now I have mavericks installed. Will the fresh install have the Mavericks or will it revert back to the OS it came with? I don't remember what that even was.

Any other tips?

Thanks all.

Yup go to the partition tab in disk utility and format to single partition, GUID. Disk utility can be selected at the start of the Mavericks Installer (or after you've booted into your recovery partition)
