How to add centeros on vmware studio

hi, 

I want to add centos7 template on vmware studio.

first, i put centos7.ios on vmware studio machine /opt/vmware/www/ISV/ISO

then, i executed the follow command.

      studiocli --newos --osdesc "CentOS 7" --profile /opt/vmware/etc/build/templates/centos/5/5_x86_64/build_profile.xml

After that i should modify the new build_profile.xml.But i don't know how to modify the file.

Can you provide me a CentOS 7 build_profile.xml file? Or where can i find one?

Thank you.
