git checkout [-q] [-f] [-m] --orphan 
Create a new orphan branch, named
<new_branch>, started from
<start_point> and switch to it. The first commit made on this new branch will have no parents and it will be the root of a new history totally disconnected from all the other branches and commits.
This can be useful when you want to publish the tree from a commit without exposing its full history. […]
If you want to start a disconnected history that records a set of paths that is totally different from the one of
<start_point>, then you should clear the index and the working tree right after creating the orphan branch by running
git rm -rf . from the top level of the working tree. […]
git checkout --orphan newbranch git rm -rf . [...] git add files git commit -m 'Initial commit'
