+# Level 1: File System Navigator 📁
+
+## Overview
+Master the fundamentals of file system operations and navigation.
+
+## Environment Setup
+```bash
+# Run the setup script
+chmod +x ~/linux-sysadmin-journey/projects/02-command-line-mastery/setup/level1-setup.sh
+./level1-setup.sh
+```
+
+## Stages
+
+### Stage 1-1: The File Hunter
+**Mission**: Master file search and manipulation techniques
+
+**Challenges**:
+
+1. **Basic Search** (100 points)
+   ```bash
+   # Find all .conf files modified in the last 3 hours
+   # Expected output: At least config_*.conf files
+   ```
+
+2. **Content Search** (150 points)
+   ```bash
+   # Find all log files containing "ERROR" and count errors per file
+   # Create a summary report
+   ```
+
+3. **Size-based Search** (200 points)
+   ```bash
+   # Locate files larger than 50MB
+   # Create a report with file sizes in human-readable format
+   ```
+
+4. **Complex Search** (250 points)
+   ```bash
+   # Find empty files AND directories
+   # Move them to ~/challenge/files/cleanup/
+   ```
+
+5. **Advanced Filter** (300 points)
+   ```bash
+   # Find files with specific permissions (600)
+   # Generate a security report
+   ```
+
+**Bonus Challenge** (+500 points):
+Create a script that:
+- Monitors directory for new files
+- Categorizes them by type
+- Moves them to appropriate subdirectories
+- Generates hourly reports
+
+**Success Criteria**:
+- [ ] All files correctly identified
+- [ ] Commands properly documented
+- [ ] Generated reports are accurate
+- [ ] Used efficient search methods
+- [ ] Implemented error handling
+
+### Stage 1-2: Permission Puzzler
+**Mission**: Master file permissions and access control
+
+**Setup Script Features**:
+- Creates complex directory structure
+- Sets various permissions
+- Simulates multi-user environment
+- Creates access control scenarios
+
+**Challenges**:
+
+1. **Basic Permissions** (100 points)
+   ```bash
+   # Fix basic file permissions
+   # Verify with ls -l
+   ```
+
+2. **Recursive Changes** (150 points)
+   ```bash
+   # Implement directory structure permissions
+   # Maintain security best practices
+   ```
+
+3. **ACL Implementation** (200 points)
+   ```bash
+   # Set up ACLs for user groups
+   # Test access scenarios
+   ```
+
+4. **Special Permissions** (250 points)
+   ```bash
+   # Configure SUID/SGID
+   # Implement sticky bits
+   ```
+
+5. **Complex Scenario** (300 points)
+   ```bash
+   # Implement full web server permissions
+   # Set up user access control
+   # Configure automated permission updates
+   ```
+
+**Bonus Challenge** (+500 points):
+Create a permission monitoring system that:
+- Detects unauthorized changes
+- Logs modification attempts
+- Reverts unauthorized changes
+- Sends notifications
+
+## Scoring System
+- Base points for completion
+- Time bonus (varies by challenge)
+- Efficiency bonus (fewer commands = more points)
+- Style points for elegant solutions
+- Documentation quality bonus
+
+## Verification Scripts
+```bash
+# Run verification
+./verify-level1.sh
+
+# Check score
+./check-score.sh
