To download the nvm installation script from the project's GitHub page, you can use curl. Note that the version number may differ from what is highlighted here:

curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh -o install_nvm.sh

Inspect the installation script with nano:

nano install_nvm.sh

Run the script with bash:

bash install_nvm.sh

It will install the software into a subdirectory of your home directory at ~/.nvm. It will also add the necessary lines to your ~/.profile file to use the file.

To gain access to the nvm functionality, you'll need to either log out and log back in again or source the ~/.profile file so that your current session knows about the changes:

source ~/.profile

With nvm installed, you can install isolated Node.js versions. For information about the versions of Node.js that are available, type:
