ZIP file contains two folders: om4 - is theme folder, upload it to yoursite/themes folder resources - contains PSD file of header used in this theme
It is based on Omnetwork Theme #3 but nice girl replaced business man. There are also changes in CSS, so this is completly different theme for different application :)
It is stretchable theme suitable for professional usage. Use this theme how ever you like, as all other resources available here.
