Netlify can be used both from a web UI or by using command line tools. You can create unlimited domains with the free account. For $45 a month you get team sharing, administrator roles, visitor password control, and email and chat support.
To start with the web UI, simply head to app.netlify.com 
To start by manually deploying a folder with a static site to Netlify, make sure you have Node.js installed and then follow these steps:
npm install netlify-cli -g; cd ~/my-static-website; netlify deploy
#Continuous Deployment For anything larger than a one page landing, you really should be using a static site generator or a front-end build tool like grunt or gulp.
If you’re using any of those, Netlify can make the process of collaborating and deploying much smoother.
Netlify lets you link a GitHub repository to a site. Each time you push to GitHub, Netlify runs a build with your tool of choice and deploys the result to our powerful CDN.
# Helpful Hints If you are creating a new site on Netlify, or just moving a pre-existing site onto the platform, it’s good to keep the following things in mind:
If the static site generator you are using is built with NodeJS make sure your package.json contains the name of your tool. Do so by running the following command in your terminal:
$ npm install TOOLNAME --save
If your project directory has the same name as your tool, the above command will fail. So make sure your project name is something different.
You also need a .nvmrc file at the root of your project to tell Netlify which version of NodeJS to use. In the terminal, enter this command:
$ node -v > .nvmrc
To create a file to tell Netlify which version of Node.js to use. The version of node you use is dynamically fetched using nvm and then cached to speed up builds. If you don’t specify a version, we default to using node 6.9.1 as of this writing (December 2016).
