Working with desired subtrees on git (sparse-checkout)

git_working_subtrees.txt

# Initialize
# Go project folder (empty) and initialize as git
git init

# Fetch tree
git remote add -f origin http://github.com/vrandkode/scratch.git

# Enable sparse-checkout and configure by listing your desired sub-trees
git config core.sparsecheckout true
echo "path/to/dir" >> .git/info/sparse-checkout
echo "path/to/some/file" >> .git/info/sparse-checkout

# Checkout from branch repo [remote] [branch]
git pull origin master

# Done

# If you later decide to change which directories you would like checked out, 
# simply edit the sparse-checkout file and run git read-tree again as above
# http://schacon.github.io/git/git-read-tree.html#_sparse_checkout
git read-tree -mu HEAD
