+# Angular-CLI
+
+## Note
+
+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](https://github.com/angular/angular-cli/issues).
+
+## Installation
+
+```bash
+npm install -g angular-cli
+```
+
+## Usage
+
+```bash
+ng --help
+```
+
+### Generating and serving an Angular2 project
+
+```bash
+ng new PROJECT_NAME
+cd PROJECT_NAME
+ng serve
+```
+
+## Development Hints
+
+### Working with master
+
+```bash
+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:
+
+```bash
+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](https://www.npmjs.org/doc/cli/npm-link.html)
+and the [npm-link cheatsheet](http://browsenpm.org/help#linkinganynpmpackagelocally) for more information.
