 ## Usage
 
 You can create an `.nvmrc` file containing version number in the project root directory (or any parent directory).

 If setting the `default` alias does not establish the node version in new shells (i.e. `nvm current` yields `system`), ensure that the system's node PATH is set before the `nvm.sh` source line in your shell profile (see [#658](https://github.com/creationix/nvm/issues/658))
