Let's start by installing Node.js and Serverless.
Serverless is a Node.js CLI tool so the first thing you need to do is to install Node.js on your machine.
Go to the official Node.js website, download and follow the installation instructions to install Node.js on your local machine.
Note: Serverless runs on Node v4 or higher. So make sure that you pick a recent Node version.
You can verify that Node.js is installed successfully by runnning node --version in your terminal. You should see the
corresponding Node version number printed out.
Great! Now we've got everything in place to install Serverless. Serverless can be easily installed via npm which was installed alongside Node.js.
Open up a terminal and type npm install -g serverless@beta to install the beta version of Serverless.
Once the installation process is done you can verify that Serverless is installed successfully by running
serverless --version. You should see version 1.0.0 printed out on the terminal!
Note: The Serverless CLI provides additional shortcuts so you don't have to type in serverless all the time.
Here's a list of all available commands you can use:

Note: If you want to run multiple Serverless versions on your machine you might want to check out this issue.
We've just installed Node.js and Serverless on our local machine! The next step is to configure our cloud provider account so that Serverless can act on our behalf and create resources for us on the cloud providers infrastructure.
