Tell me about Git. What is GitFlow? How was it used in the project?

Git is a distributed version control system that allows tracking changes in code, working in teams, and managing branches.

GitFlow is a popular branching model that structures the development process:

• master — stable version for production.
• develop — integration branch for current development.
• feature/* — branches for new features, created from develop.
• release/* — branches for preparing releases, from develop.
• hotfix/* — branches for urgent fixes, from master.

In a project, GitFlow helps organize work so that:

• New features are isolated until ready.
• Releases are prepared with testing.
• Critical bugs are quickly fixed in production.

Example usage:

# Create a branch for a new feature
git checkout develop
git checkout -b feature/new-login

# After completing work
git checkout develop
git merge feature/new-login

# Preparing a release
git checkout -b release/1.2.0 develop
# Testing and fixes

# Releasing the release
git checkout master
git merge release/1.2.0
git tag 1.2.0

# Fixing bugs in production
git checkout -b hotfix/1.2.1 master
# Fixes

# Merging fixes
git checkout master
git merge hotfix/1.2.1
git checkout develop
git merge hotfix/1.2.1
