thanks; I indeed read though the first part too fast... "HEAD is either a reference or a commit id. the reference must be a branch if using git commands" indeed

thanks; I indeed read though the first part too fast... "HEAD is either a reference or a commit id. the reference must be a branch if using git commands" indeed allows git commands to make detached heads (that surprised me a bit given she pointed at git branchless...) I'm indeed not aware of any command that's store a tag in there, ignore me!
