Initial commit

This initial version is purposely extremily limited:
* `GET /ahoy` endpoint, just to check the server is alive
* `GET /items` endpoint, always returns the same item
* `POST items` endpoint, checks and print request payload, no
  persistance
* calling any other route defaults to a 404

+# Yohoho - A take-home assignment for HolidayPirates
+
+This is my take on the take-home assignment I was given for the Backend Engineer
+position at HolidayPirates.
+
+The goal is to implement a very small REST API in Clojure. That API provides two
+endpoints :
+
+* `POST /items`: creates an item
+* `GET /items`: returns the list of items
+
+## Usage
+
+This project uses Leiningen. Assuming you already have Leiningen installed,
+running the API should be as easy as cloning the repo and issuing `lein run`. By
+default, the server listens on port 3000.
+
+## Library choices
+
+* `reitit`: for handling routes
+* `jetty`: web server
+* `muuntaja`: JSON handling
+
+## Documentation links
+
+The following links proved more than useful when working on this assignment:
