Need More steps.

can please mention steps to run the commands given. I'm using VS2013.

Getting below issue while running it.

The term 'npm' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

You need to follow the guidelines here: http://dev.office.com/sharepoint/docs/spfx/tools-and-libraries and http://dev.office.com/sharepoint/docs/spfx/set-up-your-development-environment

There is no support for Visual Studio 2013, you need to use at least Visual Studio 2015.

Closing this one, since Wictor covered the key points already a year ago.
