+# Custom Handlebars Helpers for Ghost
+This is a Ghost "App" that will implement a custom Handlebars
+helper the same as https://apatchofcode.com/adding-custom-handlebars-for-ghost-equals-awesome/
+
+## Installation
+Create a new directory in `contents/apps`
+
+eg: 
+> `mkdir contents/apps/myhelpers`
+
+Place `package.json` and `index.js` in the directory.
+
+To enable the app you need to manually add it to the database as described at: https://github.com/TryGhost/Ghost/wiki/Apps-Getting-Started-for-Ghost-Devs
+
+Restart ghost
+
+## Usage
+Simply use the new helper in your template, eg:
+
+    {{#compare 'apples' '===' 'oranges'}}
+        <p>Totally not the case.<p>
+    {{/compare}}
+    {{#compare 'apples' 'typeof' 'string'}}
+        <p>I think we're onto something.<p>
+    {{/compare}}
