+# copyFile
+
+This is a CLI built with [commander](https://www.npmjs.com/package/commander) that copies files to a specific directory path.
+
+## Usage
+
+Here is the output of running `node bin/cli.js -h` from the `copyFile` directory:
+
+```bash
+Usage: cli.js [file] [path]
+
+Options:
+  --help, -h       Show help                                           [boolean]
+  --version, v     Show version number                                 [boolean]
+```
+
+### As a Local Project
+
+You'll want to start by installing dependencies:
+
+```bash
+npm install
+```
+
+Since this is a CLI, you'll probably want to get it available on your PATH. There's two ways you can do this:
+
+**Via global installation:**
+
+```bash
+npm i -g . # this will install the current working directory as a global module. you will want to do npm uninstall -g . to uninstall it.
+copyFile copy [file] [path] # run the CLI
+```
+
+**Via symlink:**
+
+```bash
+npm link # this will create a symlink that makes the module act as a global module. npm unlink to remove this.
+copyFile copy [file] [path] # run the CLI
+```

-### As a Local Project
-
-You'll want to start by installing dependencies:
-
-```bash
-npm install
-```
-
-Since this is a CLI, you'll probably want to get it available on your PATH. There's two ways you can do this:
-
-**Via global installation:**
-
-```bash
-npm i -g . # this will install the current working directory as a global module. you will want to do npm uninstall -g . to uninstall it.
-removeFile rimraf [path] # run the CLI
-```
-
-**Via symlink:**
-
-```bash
-npm link # this will create a symlink that makes the module act as a global module. npm unlink to remove this.
-removeFile rimraf [path] # run the CLI
-```
