Why CI/CD Matters
Imagine you're working on a team project. Every time someone pushes code, you need to: 1. Pull the latest changes 2. Run tests 3. Build the project 4. Deploy to staging 5. Check if everything works Now imagine doing this manually, 10 times a day. Sounds exhausting, right? That's where CI/CD comes in!
# Real-world Scenario
# Before CI/CD:
1. Developer pushes code
2. Team lead manually pulls changes
3. Runs tests locally
4. Builds the project
5. Deploys to staging
6. Checks if everything works
7. Repeats for every change

# After CI/CD:
1. Developer pushes code
2. Everything happens automatically
3. Team gets notified of results
