Updating presta from git and switching to a working branch

For prestashop I want to work on a local branch (I use it to install my plugins as submodules)

# get remote updates
git fetch -all

# reset all uncommited changes (I don't need them anymore)
git reset --hard HEAD

# checkout 1.6 branch
git chekout 1.6

# update branch
git pull

# create new working tag
git checkout -b w1.6.0.8
