This projects is very much still a work in progress.

We still have a long way before getting out of our alpha stage. If you wish to collaborate while the project is still young, checkout our list issues.

npm install -g angular-cli

ng --help

ng new PROJECT_NAME
cd PROJECT_NAME
ng serve

git clone https://github.com/angular/angular-cli.git
cd angular-cli
npm link

npm link is very similar to npm install -g except that instead of downloading the package from the repo, the just cloned angular-cli/ folder becomes the global package. Any changes to the files in the angular-cli/ folder will immediately affect the global angular-cli package, allowing you to quickly test any changes you make to the cli project.

Now you can use angular-cli via the command line:

ng new foo
cd foo
npm link angular-cli
ng server

npm link angular-cli is needed because by default the globally installed angular-cli just loads the local angular-cli from the project which was fetched remotely from npm. npm link angular-cli symlinks the global angular-cli package to the local angular-cli package. Now the angular-cli you cloned before is in three places: The folder you cloned it into, npm's folder where it stores global packages and the angular-cli project you just created.

Please read the official npm-link documentation and the npm-link cheatsheet for more information.
