git checkout 7907137

cd ecommerceapp
git init

mkdir test
mkdir docs
touch Readme.md
touch src/main.py
touch test/main.py
touch docs/main.md

git add -A
git commit -m "Initial Folder Structure Created"
- Now this ecommerce application development is agile, We need create the branches for sprints. For now we need to create a branch called as sprint-1
git branch sprint-1
git branch
git checkout sprint-1

git add .
git commit -m " Feature 1 completed"
