+## Scenario: Creating Users with Specific Requirements
+
+### Original Problem
+From Practice Scenarios v3: Create a user named 'john' with a custom shell and home directory.
+
+### Environment
+- OS Version: Rocky Linux 8.x
+- Initial State: No user 'john' exists
+- Required Outcome: User 'john' created with specific requirements
+
+### Solution Steps
+1. Create the user with specific requirements
+   ```bash
+   # Create user with custom home directory
+   sudo useradd -m -d /custom/home/john -s /bin/bash john
+   
+   # Set password
+   sudo passwd john
+   ```
+   This creates the user 'john' with a custom home directory and bash shell
+
+2. Verify user creation
+   ```bash
+   # Check user entry in /etc/passwd
+   grep john /etc/passwd
+   
+   # Verify home directory
