Add Ansible configuration and roles for development environment setup. Introduced ansible.cfg for default settings, created README.md for documentation, and established roles for applications, base, and development tasks. Enhanced dev-playbook.yml with pre-tasks and streamlined application installations.

+# Ansible Development Environment Setup
+
+This Ansible playbook automates the setup of development environments across multiple machines.
+
+## 🏗️ Architecture
+
+### Host Groups
+- `dev`: Development machines (devVM, bottom, debianDesktopVM)
+- `gitea`: Gitea server
+- `portainer`: Portainer container management
+- `homepage`: Homepage dashboard
+- `ansible`: Ansible control node
+
+### Roles
+
+#### Core Roles
+- **`maintenance`**: System updates, package cleanup, and reboots
+- **`base`**: Core system packages, security tools, and system hardening
+- **`development`**: Development tools (git, nodejs, build-essential, python3)
+- **`shell`**: Shell configuration (zsh + oh-my-zsh + powerlevel10k)
+- **`docker`**: Docker CE installation and user configuration
+- **`ssh`**: SSH server and firewall configuration
+- **`user`**: User management
+
+#### Application Roles
+- **`applications`**: Desktop applications (Brave, LibreOffice, Redshift, Evince)
+- **`snap`**: Snap daemon and snap applications (VSCode, Cursor)
+
+## 🚀 Usage
+
+### Basic Setup
+```bash
+# Run on all development machines
+ansible-playbook dev-playbook.yml
+
+# Run on specific host
+ansible-playbook dev-playbook.yml --limit devVM
+
+# Skip reboots for specific host
+ansible-playbook dev-playbook.yml --limit bottom
+```
+
+### Skip Reboots
+Add `skip_reboot=true` to host variables:
+```ini
+[dev]
+bottom ansible_host=10.0.10.156 ansible_user=beast skip_reboot=true
+```
+
+### Dry Run
+```bash
+# Check what would be changed
+ansible-playbook dev-playbook.yml --check
+
+# Verbose output
+ansible-playbook dev-playbook.yml -v
+```
+
+## 🔧 Configuration
+
+### Global Variables (`group_vars/all.yml`)
+- `timezone`: System timezone (default: UTC)
+- `locale`: System locale (default: en_US.UTF-8)
+- `fail2ban_bantime`: Ban duration in seconds
+- `fail2ban_findtime`: Time window for failures
+- `fail2ban_maxretry`: Max failures before ban
+
+### Host Variables (`host_vars/`)
+- `skip_reboot`: Skip automatic reboots
+- Encrypted variables for sensitive data
+
+## 🛡️ Security Features
+
+### Fail2ban Configuration
+- SSH brute force protection
+- Configurable ban times and retry limits
+- Email notifications (configured in template)
+
+### UFW Firewall
+- Deny-by-default policy
+- SSH access allowed
+- Automatic enablement
+
+### System Hardening
+- Timezone and locale configuration
+- Security package installation
+- Monitoring tools (htop, iotop, nethogs, logwatch)
+
+## 📦 Installed Packages
+
+### Base System
+- `htop`, `curl`, `wget`, `unzip`, `xclip`
+- `net-tools`, `ufw`, `fail2ban`
+- `iotop`, `nethogs`, `logwatch`
+
+### Development Tools
+- `git`, `nodejs`, `npm`
+- `build-essential`, `python3`, `python3-pip`
+
+### Applications
+- `brave-browser`, `libreoffice`, `evince`, `redshift`
+- `code` (VSCode), `cursor` (via snap)
+
+### Docker
+- Docker CE with all components
+- Docker Compose
+- User added to docker group
+
+## 🔄 Maintenance
+
+### Automatic Updates
+The maintenance role handles:
+- Package updates (`apt upgrade`)
+- Unused package removal (`apt autoremove`)
+- Cache cleanup (`apt autoclean`)
+- Conditional reboots
+
+### Manual Maintenance
+```bash
+# Update only maintenance role
+ansible-playbook dev-playbook.yml --tags maintenance
+
+# Skip maintenance
+ansible-playbook dev-playbook.yml --skip-tags maintenance
+```
+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+1. **SSH Connection Issues**
+   - Check `ansible.cfg` SSH settings
+   - Verify host keys and user permissions
+
+2. **Package Installation Failures**
+   - Run with `-v` for verbose output
+   - Check internet connectivity on target hosts
+
+3. **Reboot Issues**
+   - Use `skip_reboot=true` for problematic hosts
+   - Check maintenance role handlers
+
+### Debug Commands
+```bash
+# Test connectivity
+ansible dev -m ping
+
+# Check facts
+ansible dev -m setup
+
+# Run specific role
+ansible-playbook dev-playbook.yml --tags base
+```

+## 🤝 Contributing
+
+1. Test changes with `--check` first
+2. Update documentation for new roles/tasks
+3. Use proper handlers for service restarts
+4. Follow existing naming conventions
