Inserting code into <head>my new code</head> tag

Hello everyone. I would like to get some code into a head tag for every page.
I couldn’t find it anywhere in the template. I am not afraid to code some module if it’s required, but I cant find anything where I can past a code into a head tag for every page.

Thank you so much for your answer. I am sorry for my english though.

check: application/views/azure/tpl/layout/base.tpl

Thank you mate. I didn’t see it before :smiley:
Guess I shouldn’t work anymore today.

Thank you once again.
