+# Decap CMS App
+_For a Decap CMS overview, see the general [Decap CMS project README](https://github.com/decaporg/decap-cms)._
+
+## Purpose
+This package is similar to the [`decap-cms`](https://github.com/decaporg/decap-cms/tree/main/packages/decap-cms/) package, but is designed for use with extensions. It serves that purpose in the following ways.
+
+- It does not automatically initialize - you must run the CMS `init` method.
+- It does not include `react` or `react-dom` - they are required as peer dependencies.
+- It does not include the following extensions:
+  - [`decap-cms-media-library-cloudinary`]
+  - [`decap-cms-media-library-uploadcare`]
+  
+## Usage
+Install via script tag:
+
+```html
+<!-- Excluding `doctype` and `head` but you should add them -->
+<body>
+  <!-- Add these scripts to the bottom of the body -->
+  <script src="https://unpkg.com/react@^18/umd/react.production.min.js"></script>
+  <script src="https://unpkg.com/react-dom@^18/umd/react-dom.production.min.js"></script>
+  <script src="https://unpkg.com/decap-cms-app/dist/decap-cms-app.js"></script>
+  
+  <!-- Initialize the CMS -->
+  <script>
+    DecapCmsApp.init();
+  </script>
+</body>
+```
+
+Install via npm:
+
+```
+npm i react react-dom decap-cms-app
+```
+
+```js
+import CMS from 'decap-cms-app';
+
+CMS.init();
+```
