2. Verify installation with command: nvm --version
3. Use NVM to display the available versions to install: nvm ls-remote --lts

5. Use NVM to use a specific version: nvm use vX.YY.Z

Environment

1. Ensure you have .bash_profile file with vi ~/.bash_profile
2. Add this to the file

if [ -r ~/.bashrc ]; then
   source ~/.bashrc
fi

1. Ensure you have a .bashrc file with vi ~/.bashrc
2. If you followed this README so far, you will have a .bashrc with information for NVM.
3. Add aliases, functions, and other environment customizations to the .bashrc.
