# Examples of call:

mkdir $name
cd "$name"

# Moves all the administrative git files (a.k.a $GIT_DIR) under .bare directory.
#
# Plan is to create worktrees as siblings of this directory.
# Example targeted structure:
# .bare
# main
# new-awesome-feature
# hotfix-bug-12
# ...
git clone --bare "$url" .bare
echo "gitdir: ./.bare" > .git

# Explicitly sets the remote origin fetch so we can fetch remote branches
git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"

# Gets all branches from origin
git fetch origin
