How do I install and configure git?

# Install Git ## Windows Download the installer from [git-scm.com/download/win](https://git-scm.com/download/win) and run it with default settings. ## macOS Open Terminal and run `git --version`.

How do I initialize repo and master basic commits?

# Create a Practice Project 1. Create a directory: `mkdir my-git-project && cd my-git-project` 2. Initialize: `git init` 3. Create a file: Use your editor to make `README.md` with some content. # Basic Workflow ``` git add README.md git status git commit -m "Initial commit" git log --oneline ``` Repeat: Edit file, `git add .`, `git status`, `git commit -m "Update message"`, `git log`.

How do I inspect changes: status, diff, and log?

# Key Inspection Commands ``` git status # Current state git diff # Unstaged changes git diff --staged # Staged changes git diff HEAD # All changes since last commit git log --oneline --graph # Pretty history git log --follow README.md # File history ``` Practice: Edit files, run `git status`, stage some, diff, commit, then log. Use `git show ` for specific commit details.

How do I branch, switch, and merge effectively?

# Branching Workflow ``` # From main, create & switch git switch -c feature-branch # Edit, add, commit git add . git commit -m "Add feature" # Back to main git switch main git switch -c hotfix git commit -m "Fix bug" # Merge hotfix git switch main git merge hotfix git branch -d hotfix git switch main git merge feature-branch git branch -d feature-branch ``` View branches: `git branch`. Practice multiple times.

How do I push to github: remotes and collaboration?

# Setup Remote 1. Create free GitHub account at github.com. 2. Create new repo on GitHub (no README). 3. Add remote: `git remote add origin https://github.com/YOUR_USERNAME/YOUR_REPO.git` 4. Push: ``` git branch -M main git push -u origin main ``` # Pull Changes ``` git fetch origin git pull origin main ``` Clone test: `git clone https://github.com/YOUR_USERNAME/YOUR_REPO.git test-clone`.
