# Complete Gitea Setup Guide for Beginners

## A) Initial Setup of Gitea on Computer

### 1. Install Git on Your Computer

**Windows:**
- Download Git from https://git-scm.com/download/win
- Run installer with default settings
- Open Git Bash or Command Prompt

**macOS:**
- Install via Homebrew: `brew install git`
- Or download from https://git-scm.com/download/mac

**Linux (Ubuntu/Debian):**
- Install via package manager: `sudo apt-get install git`

### 2. Verify Git Installation
```bash
git --version
```

### 3. Connect Computer to Your Existing Codebase/Folder

**Option 1: Connect Existing Local Folder to Gitea**
```bash
cd /path/to/your/existing/project
git init
git remote add origin git@your-gitea-server:username/repository-name.git
git add .
git commit -m "Initial commit"
git push -u origin main
```

**Option 2: Clone Existing Repository from Gitea**
```bash
git clone git@your-gitea-server:username/repository-name.git
cd repository-name
```

## B) Initial Configuration on New Computer

### 1. Configure Git Identity
```bash
git config --global user.name "Your Full Name"
git config --global user.email "your.email@example.com"
git config --global core.editor "nano"  # or "code" for VS Code
git config --global color.ui true
```

### 2. Generate SSH Key for Secure Authentication
```bash
# Generate new SSH key
ssh-keygen -t ed25519 -C "your.email@example.com"

# Start SSH agent
eval "$(ssh-agent -s)"

# Add key to agent
ssh-add ~/.ssh/id_ed25519

# Display public key to copy to Gitea
cat ~/.ssh/id_ed25519.pub
```

### 3. Add SSH Key to Gitea Account
1. Copy the public key output from above
2. Log into Gitea web interface
3. Go to Settings > SSH/GPG Keys
4. Click "Add Key"
5. Paste public key in Content field
6. Click "Add Key"

### 4. Test SSH Connection
```bash
ssh -T git@your-gitea-server.com
```
You should see a success message.

### 5. Set Up Git Aliases (Optional but Helpful)
```bash
git config --global alias.st status
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.lg "log --oneline --graph --decorate"
```

## C) Steps to Form a New Project Each Time

### 1. Create Repository in Gitea Web Interface
1. Log into Gitea
2. Click "+" menu in top-right corner
3. Select "New Repository"
4. Fill out repository details:
   - **Repository Name:** use-lowercase-with-hyphens
   - **Description:** Brief project description
   - **Visibility:** Public or Private
   - **Initialize Repository:** Check if starting fresh
   - **Add .gitignore:** Select template for your language
   - **Add License:** Choose appropriate license
5. Click "Create Repository"

### 2. Clone and Set Up Locally
```bash
# Clone the new repository
git clone git@your-gitea-server:username/repository-name.git

# Navigate to project directory
cd repository-name

# Create basic project structure
mkdir src docs tests
touch src/main.py  # or main.js, main.cpp, etc.

# Add initial files
git add .
git commit -m "Initial project structure"
git push origin main
```

### 3. Create Development Branch
```bash
# Create and switch to development branch
git checkout -b develop

# Push development branch to remote
git push -u origin develop
```

## E) Very Detailed Daily Coding Workflow

### 1. Start of Each Work Session
```bash
# Check current status
git status

# Get latest changes from remote
git pull origin main

# Create new feature branch (use descriptive names)
git checkout -b feature/add-user-authentication
# or
git checkout -b bugfix/fix-login-error
# or  
git checkout -b docs/update-readme
```

### 2. During Development

#### Making Changes
```bash
# Check what files have changed
git status

# See specific changes in files
git diff

# See changes for specific file
git diff filename.py
```

#### Staging and Committing Changes
```bash
# Stage specific files
git add src/auth.py src/login.py

# Or stage all changes
git add .

# Or stage all changes in current directory
git add -A

# Check what's staged
git status

# Commit with descriptive message
git commit -m "Add user authentication with email verification"

# Or commit with detailed message
git commit -m "Add user authentication system

- Implement email-based user registration
- Add password hashing with bcrypt
- Create login/logout functionality
- Add session management
- Include email verification workflow

Fixes #123"
```

#### Best Practices for Commit Messages
- Use present tense imperative mood ("Add feature" not "Added feature")
- Keep first line under 50 characters
- Add blank line before detailed description
- Reference issue numbers when applicable
- Use conventional commit format:
  - `feat:` for new features
  - `fix:` for bug fixes
  - `docs:` for documentation
  - `style:` for formatting changes
  - `refactor:` for code refactoring
  - `test:` for adding tests

#### Pushing Changes
```bash
# Push current branch to remote
git push origin feature/add-user-authentication

# If first time pushing this branch
git push -u origin feature/add-user-authentication
```

### 3. Checking Progress and History
```bash
# View commit history
git log --oneline

# View detailed history
git log --graph --decorate --oneline

# View changes between commits
git log -p

# View specific file history
git log --follow filename.py

# View who changed what in a file
git blame filename.py
```

### 4. Handling Merge Conflicts
```bash
# If pull/merge results in conflicts
git status  # Shows conflicted files

# Edit conflicted files manually, looking for:
# <<<<<<< HEAD
# Your changes
# =======
# Their changes
# >>>>>>> branch-name

# After resolving conflicts
git add conflicted-file.py
git commit -m "Resolve merge conflict in user authentication"
```

### 5. End of Feature Development
```bash
# Switch back to main branch
git checkout main

# Get latest changes
git pull origin main

# Merge feature branch
git merge feature/add-user-authentication

# Push merged changes
git push origin main

# Delete feature branch locally
git branch -d feature/add-user-authentication

# Delete feature branch on remote
git push origin --delete feature/add-user-authentication
```

### 6. Daily Maintenance Commands
```bash
# See all branches (local and remote)
git branch -a

# See remote repositories
git remote -v

# Clean up remote tracking branches
git remote prune origin

# See repository status
git status

# See what's different from last commit
git diff HEAD~1

# Undo last commit (but keep changes)
git reset --soft HEAD~1

# Undo changes to a file
git checkout -- filename.py

# Create and apply patches
git format-patch -1 HEAD
git apply patch-file.patch
```

### 7. Working with Multiple Remotes
```bash
# Add additional remote (e.g., for backup)
git remote add backup git@backup-server:username/repository.git

# Push to specific remote
git push backup main

# Pull from specific remote
git pull backup main
```

### 8. Stashing Work in Progress
```bash
# Save current work without committing
git stash push -m "Work in progress on authentication"

# List stashes
git stash list

# Apply most recent stash
git stash pop

# Apply specific stash
git stash apply stash@{1}

# Drop a stash
git stash drop stash@{1}
```

### 9. Emergency Procedures

#### Undo Last Commit
```bash
# Undo last commit but keep changes
git reset --soft HEAD~1

# Undo last commit and lose changes
git reset --hard HEAD~1
```

#### Recovery
```bash
# Find lost commits
git reflog

# Recover specific commit
git checkout commit-hash

# Create branch from recovered commit
git checkout -b recovery-branch
```
