+# Vert.x Kotlin Example
+
+Basic JSON API written in [Kotlin](https://kotlinlang.org/) to demonstrate how it can be used with Vert.x.
+
+This project is built on Gradle and is ready to be deployed on Heroku, hence it combines parts of the following 
+examples:
+
+- Gradle:
+    - [gradle-redeploy](https://github.com/vert-x3/vertx-examples/tree/master/gradle-redeploy)
+    - [gradle-simplest](https://github.com/vert-x3/vertx-examples/tree/master/gradle-simplest)
+    - [gradle-verticles](https://github.com/vert-x3/vertx-examples/tree/master/gradle-verticles)
+- Heroku:
+    - [heroku-example](https://github.com/vert-x3/vertx-examples/tree/master/heroku-example)
+
+## Running
+
+The most convenient way to run the project during development is as follows:
+
+```
+./gradlew run
+```
+
+That way, any changes to the classes will be picked up and re-deployed automatically.
+
+## Deploying
+
+The application can either be deployed manually (with a jar file) or to [Heroku](https://www.heroku.com/).
+
+### Manually
+
+You can generate a single "shadow jar" (more on that [here](https://github.com/johnrengelman/shadow)) as follows:
+
+```
+./gradlew shadowJar
+```
+
+The jar file can now be retrieved from `./build/libs/app-shadow.jar` and deployed onto your preferred platform.
+
+### Heroku
+
+This project includes a custom `Procfile` to simplify deployment to Heroku, however you would need to place the 
+contents of this example into a separate Git repository first (because the global [`Procfile`](https://github.com/vert-x3/vertx-examples/blob/master/Procfile) 
+in the root directory points to the `heroku-example`).
+
+Once in your new Git repository, install the [Heroku Toolbelt](https://toolbelt.heroku.com/) and issue the 
+following:
+
+```
+heroku login
+heroku create
+git push heroku master
+```
+
+*Note:* All your changes must be committed to Git before issuing the last command.
