The situation becomes a little bit problematic if we want to create a branch from a tag with the same name   In this  and in similar scenarios  the important thing is to know  branches and tags are actually single-line text files in  git refs directory  and we can reference them explicitly using their pathes below  git  Branches are called here  heads   to make our life more simple   Thus  refs heads master is the real  explicit name of the master branch  And refs tags cica is the exact name of the tag named cica   The correct command to create a branch named cica from the tag named cica is   git branch cica refs tags cica
