+# Conche CLI Example
+
+This repository is a small example command line interface using the Conche
+build system. It was mostly generated via `conche init`.
+
+```shell
+$ conche init Hello --with-cli --with-tests
+```
+
+## Usage
+
+This example provides a command called `hello` which can output Hello World
+or Hello and some given names.
+
+```shell
+$ hello
+Hello World
+
+$ hello Kyle
+Hello Kyle
+
+$ hello Kyle Katie
+Hello Kyle and Katie
+```
+
+### Installation
+
+Using Conche, the example can be installed using `conche install`.
+
+```shell
+$ conche install
+```
+
+By default, it will install the tool into `/usr/local`, you can pass in a
+custom destination using `--prefix`.
+
+```shell
+$ conche install --prefix /usr/local/Cellar/hello/HEAD
+```
+
+### Running the tests
+
+```shell
+$ conche test
+```
+
+### Running `hello` without installing
+
+You can use `conche` to build and run the `hello` example without
+installing it to your system as follows:
+
+```shell
+$ conche build
+$ conche exec hello
+```
