+
+## Overview
+Spiders love to spider.  To show our love to all the spiders out there, this plugin reads 
+the graph and renders a sitemap.xml.  Currently, it handles up to 10000 content entries, warning 
+after 9000 content entries.
+
+## Usage
+Add this plugin to your _greenwood.config.js_ and spread the `export`.  
+
+```javascript
+import { greenwoodPluginDynamicExport } from '@greenwood/plugin-dynamic-sitemap';
+
+export default {
+  ...
+
+  plugins: [
+    greenwoodPluginDynamicExport({
+      "baseUrl": "https://example.com"
+    })
+  ]
+}
