+# Attributes API
+This API example demonstrates how to describe body attributes of a request or response message.
+
+In this case, the description is complementary (and duplicate!) to the provided JSON example in the body section. The [Advanced Attributes](09.%20Advanced%20Attributes.md) API example will demonstrate how to avoid duplicates and how to reuse attributes descriptions.

+# The Simplest API
+This is one of the simplest APIs written in the **API Blueprint**.
+One plain resource combined with a method and that's it! We will explain what is going on in the next installment - [Resource and Actions](02.%20Resource%20and%20Actions.md).
+
+**Note:** As we progress through the examples, do not also forget to view the [Raw](https://raw.github.com/apiaryio/api-blueprint/master/examples/01.%20Simplest%20API.md) code to see what is really going on in the API Blueprint, as opposed to just seeing the output of the Github Markdown parser.
+
+Also please keep in mind that every single example in this course is a **real API Blueprint** and as such you can **parse** it with the [API Blueprint parser](https://github.com/apiaryio/drafter) or one of its [bindings](https://github.com/apiaryio/drafter#bindings).
