   return {
     "username/plugin-name",
     config = function()
       -- plugin configuration
     end
   }

2. Restart Neovim - Lazy.nvim will auto-install

Changing Theme

Edit lua/plugins/colorscheme.lua:

return {
  "your-theme/nvim",
  config = function()
    vim.cmd("colorscheme your-theme")
  end
}

Custom Keymaps

Add to lua/config/keymaps.lua:

vim.keymap.set("n", "<your-key>", "<your-command>")

🐛 Troubleshooting

Plugin Issues

# Remove plugin cache
rm -rf ~/.local/share/nvim/lazy/

# Restart Neovim
nvim

LSP Not Working

# Check LSP servers
:Mason
# Install required servers: ruby-lsp, solargraph, etc.

Performance Issues

# Check startup time
nvim --startuptime startup.log

# Disable heavy plugins temporarily
# Edit respective plugin files and set enabled = false
