yeoman community is very powerful
YEOMAN is project template generator, few weeks ago the most used one was html and angular. But looks this screen, it contains 662 generators now.
Project template generator is like Visual Studio's default project template, for example the MVC 3 web application will generator all the default fiels. YEOMAN template is doing the same thing. However, looks like this community is become bigger and bigger, so I have to keep using it.
