## Installation Process

1. The script will first set up necessary package repositories:
   - Nala package manager
   - VS Code
   - GitHub CLI

2. Install core packages using Nala for better performance

3. Install special tools not available via apt:
   - Lazydocker (Docker TUI manager)

4. Set up the shell environment:
   - Install Zsh and Oh My Zsh
   - Configure Zsh plugins and themes
   - Set up custom aliases and configurations

5. Install development tools:
   - Set up nvm and Node.js
   - Configure zoxide for better navigation
   - Install and configure Git

## Testing

The repository includes a comprehensive testing framework to validate the shell setup process across different environments.

### Docker-Based Testing

Tests are run in isolated Docker containers to ensure consistent, repeatable validation:
- **Ubuntu 24.04 environment**: Tests compatibility with the latest Ubuntu LTS
- **Debian 12 environment**: Tests compatibility with Debian Stable

### Test Coverage

The tests validate:
- Package availability in repositories
- Successful installation of all packages in `packages.list`
- Oh My Zsh installation
- Zsh plugin installation
- Dotfile symlinking
- NVM and Node.js setup

### Running Tests

```bash
# Test your setup on Ubuntu
./run-docker-tests.sh ubuntu

# Test your setup on Debian
./run-docker-tests.sh debian

# Run a full bootstrap test (including installation)
./run-docker-tests.sh full-ubuntu
```

For more details on testing, see [Docker Bootstrap Testing Framework](../docs/docker-bootstrap-testing-framework.md).

## Manual Steps

If you need to manually set up aliases:

```sh
# Create new symlink
ln -s ~/shell/dotfiles/my-aliases.zsh ~/.oh-my-zsh/custom/aliases.zsh

# If the symlink already exists, use -f to force creation
ln -sf ~/shell/dotfiles/my-aliases.zsh ~/.oh-my-zsh/custom/aliases.zsh
```

## Post-Installation

After installation:
1. Start a new terminal session or run `zsh`
2. The shell will be configured with all plugins and settings
3. You can start using all installed tools and aliases

## Maintenance

To update your setup:
1. Pull the latest changes from the repository
2. Run the setup script again - it's designed to be idempotent
3. Start a new shell session to apply any changes
