Running version 1.1.7.

Usage:

  nvm arch                     : Show if node is running in 32 or 64 bit mode.
  nvm install <version> [arch] : The version can be a node.js version or "latest" for the latest stable version.
                                 Optionally specify whether to install the 32 or 64 bit version (defaults to system arch).
                                 Set [arch] to "all" to install 32 AND 64 bit versions.
                                 Add --insecure to the end of this command to bypass SSL validation of the remote download server.
  nvm list [available]         : List the node.js installations. Type "available" at the end to see what can be installed. Aliased as ls.
  nvm on                       : Enable node.js version management.
  nvm off                      : Disable node.js version management.
  nvm proxy [url]              : Set a proxy to use for downloads. Leave [url] blank to see the current proxy.
                                 Set [url] to "none" to remove the proxy.
  nvm node_mirror [url]        : Set the node mirror. Defaults to https://nodejs.org/dist/. Leave [url] blank to use default url.
  nvm npm_mirror [url]         : Set the npm mirror. Defaults to Https://GitHub.com/npm/cli/arcHive/. Leave [url] blank to default url.
  nvm uninstall <version>      : The version must be a specific version.
  nvm use [version] [arch]     : Switch to use the specified version. Optionally specify 32/64bit architecture.
                                 nvm use <arch> will continue using the selected version, but switch to 32/64 bit mode.
  nvm root [path]              : Set the directory where nvm should store different versions of node.js.
                                 If <path> is not set, the current root will be displayed.
  nvm version                  : Displays the current running version of nvm for windows. Aliased as v.
