For the first you have to create live branch if you don't have live branch on your repo
git checkout -b live
Branch is available on github repo but not in your computer
git fetch origin
# create a new branch from existing branch
git checkout -b `live` origin/live
# Go to live brnach
git checkout live
# build your code
gulp build
# push code to github
git push origin live
### Congratulations 🔥
