🎨 Customization

The configuration is modular and well-documented. Key areas for customization:

• Theme: Change colorscheme onedark in the theme section
• Key mappings: Modify the "Key Mappings" section
• Plugin settings: Adjust in the "Plugin Configs" section
• Linters/Formatters: Update ALE configuration for your tools

🐛 Troubleshooting

Common Issues

1. Plugins not loading: Run :PlugInstall in Vim
2. CoC.nvim errors: Install Node.js and run :CocInstall for language servers
3. Linting not working: Ensure tools like black, shellcheck, hadolint are installed
4. Icons not showing: Install a Nerd Font and configure your terminal

Performance

The configuration uses lazy loading to maintain fast startup times. Plugins load only when needed:

• File type specific plugins load for relevant files
• UI plugins load on command
• Heavy plugins are deferred until first use
