 This folder contains small example apps that get in-lined into our API docs.
 Each example contains tests for application behavior (as opposed to testing Angular's
 behavior) just like an Angular application developer would write.

+# Running the examples
+
+```
+# # execute the following command only when framework code changes
+./build.sh
+
+# run when test change
+./modules/@angular/examples/build.sh  
+
+# start server
+$(npm bin)/gulp serve-examples
+```

+# Running the tests
+
+```
+ # run only when framework code changes
+./build.sh
+
+# run to compile tests and run them
+./modules/@angular/examples/test.sh
+```

+NOTE: sometimes the http server does not exits properly and it retans the `8001` port.
+ in such a case you can use `lsof -i:8001` to see which process it is and then use `kill` 
+ to remove it. (Or in single command: `lsof -i:8001 -t | xargs kill`)
