-Now we're cooking, time to actually build something!
+Awesome, we have life! - Let's test some more, remember the other endpoint?...

+
+Not found... Curious?\
+The reason is simple, remember the endpoint `/items` requires a **none-optional** _path-variable_ `item_id`\
+FastAPI will enforce that! - let's try again...
+
+`curl -sS localhost:${HTTP_PORT:-9000}/items/id-1 | jq .`
+
+```
+{
+ "detail": [
+    {
+      "loc": [
+        "path",
+        "item_id"
+      ],
+      "msg": "value is not a valid integer",
+      "type": "type_error.integer"
+    }
+  ]
+}
+```
+
+This one you might have guessed already, remember we defined item_id as `item_id :int` in the function\
+You can rest assured, FastAPI we'll type check that - less type checking in our business logic, nice!
+
+Let's get a proper result, this time adding the **optional** query-string argument `q` as well
+
+`curl -sS localhost:${HTTP_PORT:-9000}/items/1?q=abc | jq .`
+
+```
+{
+  "item_id": 1,
+  "q": "abc"
+}
+```
+
+Cool, but aren't we leaving
+
+Knowing that we can test from the shell is nice, and very useful for automation, but lets head over to the browser shall we?
+
+Open [https://your.ibmi.rocks/](https://your.ibmi.rocks/{your-workshop-id}/) and enter your user id, the resulting URI is the one we'll work with from here on out.
+
+Lets end the service by bringing it to the foreground, and stopping it.
+
+To bring the process back to the foreground run `fg`\
+Now simply cancel it by pressing `Ctrl+c`
+
+Good stuff, time to actually build something!
