+### Creating our first endpoint
+
+Create a hello world endpoint using annotations.
+
+- create a java class
+- add `@Controller("/path")` annotation at class level
+- add `@Get(produces = MediaType.TEXT_PLAIN)` at method level
+
+**NOTE**: access http://localhost:8080/hello to see plain text hello world displayed.
+
+
+
+### First micronaut test experience
+
+*Let's automate - making sure that written code works*
+
+- create a test class in test folder
+- add annotation `@MicronautTest` at class level
+- add a class with `@Test` annotation
+- create a HttpClient using `@Inject` & `@Client("/")`
+- use the `HttpClient client` as a blocking client (for simplicity now) and query the `/hello` endpoint
+
+**NOTE**: by default a `@MicronautTest` is a functionnal test. So to create a unit test simply remove the annotation and use your prefered test framework.
