The following command will install the Client SDK into the
node_modules directory within your project folder:
npm install nexmo-client --save

The Nexmo CLI allows you to carry out many operations on the command line. Examples include creating applications, purchasing numbers, and linking a number to an application.
To install the Beta version of the CLI with NPM you can use:
npm install nexmo-cli@beta -g
