 Simple Scaffold allows you to create your structured files based on templates.
 
 ## Install

 You can either use it as a command line tool or import into your own code and run from there.

 You can add this as a script in your `package.json`:
 
 ```json
 {
   "scripts": {
-    "scaffold": "node node_modules/simple-scaffold/dist/cmd.js --template scaffolds/component/**/* --output src/components --locals myProp=\"propname\",myVal=123"

   }
 }
 ```
 
 ## Scaffolding
+
 Scaffolding will replace {{vars}} in both the file name and its contents and put the transformed files
 in `<output>/<{{Name}}>`, as per the Handlebars formatting rules.
 
 Your context will be pre-populated with the following:
+
 - `{{Name}}`: CapitalizedName of the component
 - `{{name}}`: camelCasedName of the component

 They are all stringified, so be sure to parse them accordingly by creating a script, if necessary.
 
 ### Use in Node.js
+
 You can also build the scaffold yourself, if you want to create more complex arguments or scaffold groups.
 Simply pass a config object to the constructor, and invoke `run()` when you are ready to start.
 The config takes similar arguments to the command line:
 
 ```javascript
-const SimpleScaffold = require('simple-scaffold').default
+const SimpleScaffold = require("simple-scaffold").default
 
 const scaffold = new SimpleScaffold({
-  name: 'component',
-  templates: [path.join(__dirname, 'scaffolds', 'component')],

+  name: "component",
+  templates: [path.join(__dirname, "scaffolds", "component")],

   createSubFolder: true,
   locals: {
-    property: 'value',
-  }
+    property: "value",
+  },
 }).run()
 ```
 
 The exception in the config is that `output`, when used in Node directly, may also be passed a function for each input file to output into a dynamic path:
+
 ```javascript
 config.output = (filename, basePath) => [basePath, filename].join(path.sep)
