 ## Quick Start
 
+### Leiningen Template
+
 Use [Leiningen](http://leiningen.org/) to create a [template](https://github.com/zero-one-group/geni-template) of a Geni project:
 
 ```bash
 lein new geni <project-name>
 ```

+### Geni REPL Uberjar
+
+Download the latest Geni REPL uberjar from the [release](https://github.com/zero-one-group/geni/releases) page. Run the uberjar as follows:
+
+```bash
+java -jar <uberjar-name>
+```
+
+The uberjar app prints the default `SparkSession` instance, starts an nREPL server with an `.nrepl-port` file for easy text-editor connection and steps into a Clojure REPL(-y).
