+# GitHub Repository Cheatsheet
+
+## Quick Reference Guide for Git and GitHub Workflows
+
+| Command | Description | Example | Notes |
+|---------|-------------|---------|-------|
+| **Repository Setup** ||||
+| `git init` | Initialize a new local repository | `git init my-project` | Creates a new .git directory |
+| `git clone [url]` | Clone a repository from remote | `git clone https://github.com/user/repo.git` | Downloads full history |
+| `git remote add origin [url]` | Connect local repo to remote | `git remote add origin https://github.com/user/repo.git` | Sets up "origin" remote |
+| `git remote -v` | List remote connections | `git remote -v` | Shows fetch/push URLs |
+| **Basic Workflow** ||||
+| `git status` | Check repository status | `git status` | Shows modified/staged files |
+| `git add [file]` | Stage changes | `git add index.html` or `git add .` | Prepares files for commit |
+| `git commit -m "[message]"` | Commit staged changes | `git commit -m "Fix navigation bug"` | Creates a commit snapshot |
+| `git pull` | Fetch and merge remote changes | `git pull origin main` | Updates local branch |
+| `git push` | Push commits to remote | `git push origin main` | Uploads local commits |
+| **Branching** ||||
+| `git branch` | List local branches | `git branch` | Current branch has asterisk |
+| `git branch [name]` | Create new branch | `git branch feature-login` | Creates branch at current commit |
+| `git checkout [branch]` | Switch branches | `git checkout feature-login` | Updates working directory |
+| `git checkout -b [name]` | Create and checkout branch | `git checkout -b feature-login` | Combines branch + checkout |
+| `git merge [branch]` | Merge branch into current | `git merge feature-login` | Integrates branch changes |
+| `git branch -d [name]` | Delete branch | `git branch -d feature-login` | Removes merged branch |
+| `git branch -D [name]` | Force delete branch | `git branch -D feature-login` | Removes unmerged branch |
+| **Branching Strategies** ||||
+| Git Flow | Main/Develop with feature branches | `git checkout -b feature/login develop` | Complex but structured |
+| GitHub Flow | Single main with feature branches | `git checkout -b feature-login main` | Simpler, PR-based |
+| Trunk-Based | Short-lived branches off main | `git checkout -b fix-404-error main` | Quick integration cycles |
+| **Pull Request Workflow** ||||
+| Create PR | Via GitHub UI | Click "New pull request" on repo page | Compare branches |
+| Review PR | Via GitHub UI | Add comments, request changes | Code review process |
+| Merge PR | Via GitHub UI | Click "Merge pull request" | Can squash or rebase |
+| `git fetch origin pull/ID/head:BRANCHNAME` | Get PR locally | `git fetch origin pull/123/head:pr-123` | For local PR testing |
+| **History & Changes** ||||
+| `git log` | View commit history | `git log --oneline` | Shows commit list |
+| `git diff` | Show unstaged changes | `git diff` | Compare working to staged |
+| `git diff --staged` | Show staged changes | `git diff --staged` | Compare staged to last commit |
+| `git reset HEAD [file]` | Unstage changes | `git reset HEAD index.html` | Keeps file changes |
+| `git checkout -- [file]` | Discard changes | `git checkout -- index.html` | Loses uncommitted changes |
+| **Advanced Commands** ||||
+| `git stash` | Stash uncommitted changes | `git stash save "WIP homepage"` | Temporarily stores changes |
+| `git stash pop` | Apply stashed changes | `git stash pop` | Reapplies and drops stash |
+| `git rebase [branch]` | Reapply commits on branch | `git rebase main` | Rewrites commit history |
+| `git tag [name]` | Create a tag | `git tag v1.0.0` | Marks specific commit |
+| `git cherry-pick [commit]` | Apply commit to current branch | `git cherry-pick abc123` | Takes single commit |
+
+## Common Branching Strategies
+
+1. **Git Flow**
+   - `main` - production-ready code
+   - `develop` - integration branch for features
+   - `feature/*` - new features
+   - `release/*` - prepare for release
+   - `hotfix/*` - urgent production fixes
+
+2. **GitHub Flow**
+   - `main` - always deployable
+   - feature branches - all work happens here
+   - pull requests - for code review and discussion
+   - deploy after merge to main
+
+3. **Trunk-Based Development**
+   - `main` - primary branch
+   - short-lived feature branches
+   - frequent integration to main
+   - feature flags for incomplete work
