+# nvm plugin
+
+This plugin adds autocompletions for [nvm](https://github.com/nvm-sh/nvm) — a Node.js version manager. It also
+automatically sources nvm, so you don't need to do it manually in your `.zshrc`.
+
+To use it, add `nvm` to the plugins array of your zshrc file:
+
+```zsh
+plugins=(... nvm)
+```
+
+## Settings
+
+If you installed nvm in a directory other than `$HOME/.nvm`, set and export `NVM_DIR` to be the directory
+where you installed nvm.
+
+These settings should go in your zshrc file, before Oh My Zsh is sourced:
+
+- **`NVM_HOMEBREW`**: if you installed nvm via Homebrew, in a directory other than `/usr/local/opt/nvm`, you
+  can set `NVM_HOMEBREW` to be the directory where you installed it. For example, on Apple Silicon-based Macs,
+  [Homebrew is installed in `/opt/homebrew`](https://docs.brew.sh/Installation). To get the directory where
+  nvm has been installed, regardless of chip architecture, use `NVM_HOMEBREW=$(brew --prefix nvm)`.
+
+## Customization
+
+#### Lazy startup
+
+This option will help you to defer nvm's load until you use it to speed-up your zsh startup. This will source
+nvm script only when using it, and will create a function for `node`, `npm`, `npx`, `pnpm`, `pnpx`, `yarn`,
+`corepack` and the command(s) specified by `lazy-cmd` option, so when you call either of them, nvm will be
+loaded and run with default version. To enable it, you can add this snippet to your zshrc, before Oh My Zsh is
+sourced:
+
+```zsh
+zstyle ':omz:plugins:nvm' lazy yes
+```
+
+Then, to define extra commands that will also trigger nvm load, you can use a similar syntax, adding as many
+as you want:
+
+```zsh
+zstyle ':omz:plugins:nvm' lazy-cmd eslint prettier typescript ...
+```
+
+There will be a function `_omz_nvm_load` available to load `nvm` without executing any other trigger command.
+
+#### `.nvmrc` autoload
+
+Note: _if used at the same time as `lazy`, `autoload` will start working only after nvm has been lazy-loaded_
+
+If set, the plugin will automatically load a node version when if finds a
+[`.nvmrc` file](https://github.com/nvm-sh/nvm#nvmrc) in the current working directory indicating which node
+version to load. This can be done, similar as previous options, adding:
+
+```zsh
+zstyle ':omz:plugins:nvm' autoload yes
+zstyle ':omz:plugins:nvm' silent-autoload yes # optionally remove the output generated by NVM when autoloading
+```
+
+Note: _this will not remove regular `nvm` output_
