+## Neovim plugins
+
+Neovim uses [lazy.nvim](https://github.com/folke/lazy.nvim) and bootstraps it automatically.
+
+1. Launch Neovim (`nvim`).
+2. Run `:Lazy sync` to clone and build all plugins (this replaces the old `:BundleInstall`).
+3. Restart Neovim once the sync completes so all remote plugins are registered.
+
+The Lua configuration re-sources your `~/.vimrc` so all of the existing
+Vimscript options, keybindings, and autocommands remain active in Neovim. If
+`~/.vimrc` is not available, it falls back to the tracked snapshot at
+`nvim/legacy.vim`.
