+# Leiningen Template: Simple Clojure App
+
+A Leiningen template intended for creating new Clojure CLI app or tool projects using a simplified / stripped-down base.
+
+This template primarily exists for my own personal use, so some stuff is definitely more oriented towards
+my own particular preferences regarding setup and organization of a Clojure project.
+
+## Usage
+
+```text
+$ lein new net.gered/simple-app [your-project-name-here]
+```
+
+The resulting project starts up via a `main` function and during startup expects to be able to read an EDN configuration file
+located in the current working directory called `config.edn`.
+
+The project can be run simply by:
+
+```text
+$ lein run
+```
+
+A nREPL server will be started which can be connected to on port 4000 (configured via the aforementioned `config.edn`).
