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 to install Serverless.
Once the installation process is done you can verify that Serverless is installed successfully by running serverless --version
In order for serverless to act on your behalf, you will need to connect your providers account. (AWS, Azure, etc.)
We've just installed Node.js and Serverless on our local machine and configured our AWS account! Now lets create our first service.
