What are the steps to run demo app locally? Not import to another project, clone repo and ng serve

[adgellida]

Hello, I'm new on Angular and I deployed hello-world app. I tried to import this module in this app with not success.

• Installed npm and nodejs correctly
• mkdir angularjs-slider
• cd angularjs-slider
• git clone https://github.com/angular-slider/angularjs-slider.git
• cd angularjs-slider
• sudo npm install phantomjs-prebuilt@2.1.16 --ignore-scripts
• -ng serve --open

Error: This command is not available when running the Angular CLI outside a workspace.

This error appears before on hello-world, I did "cd hello-world" and "ng server --open" and solved it (a common beginner error). But here I don't now what to do.

If clone and serve is not possible, I need steps to import to hello-world app for example.

Thanks. Great module!
