To install hubflow it is recommended to use git bash and run the git bash as administrator for the following commands.
git clone https://github.com/datasift/gitflow hubflow
cd hubflow
cp git-hf* '/mingw64/bin/'
cp hubflow-common '/mingw64/bin/'
git submodule update --remote --init --checkout
cp shFlags/src/shflags '/mingw64/bin/hubflow-shFlags'
git hf help
It's much easier to have git bash in your windows system to use hubflow.
If you find any difficulties try running the commands which includes path, without quotes. example:
replace cp hubflow-common '/mingw64/bin/' with cp hubflow-common /mingw64/bin/
