xwiki drawer item add

Hi! i need help! how can i add item to drawer menu
I find instruction to add:
velocityhtml clean="false" ## we need clean="false" because we want to display the raw content of #drawerItem()
#template('drawer_macros.vm')
#drawerTopItemStart('some icon', 'some xml-escaped title' , 'some HTML id')
#drawerItem('someURL', 'someIcon', 'some xml-escaped text', 'some HTML id')
#drawerItem('someURL', 'someIcon', 'some xml-escaped text', 'some HTML id')
#drawerItem('someURL', 'someIcon', 'some xml-escaped text', 'some HTML id')
#drawerTopItemStop()
/html/velocity

Only I can't find where to insert it.....
