+# @flatfile/plugin-enrich-summarize
+
+This plugin provides automatic text summarization capabilities for Flatfile using natural language processing. It uses the compromise library to generate summaries and extract key phrases from specified fields.
+
+**Event Type:** `commit:created`
+
+**Supported Field Types:** `string`
+
+<!-- END_INFOCARD -->
+
+## Features
+
+- Automatic text summarization
+- Key phrase extraction
+- Configurable summary length or percentage
+- Custom field mapping for content, summary, and key phrases
+- Error handling for missing content
+
+## Parameters
+
+#### `sheetSlug` - `string` - (required)
+The slug of the sheet to apply summarization.
+
+#### `contentField` - `string` - (required)
+The field containing the full text content.
+
+#### `summaryField` - `string` - (required)
+The field to store the generated summary.
+
+#### `keyPhrasesField` - `string` - (required)
+The field to store extracted key phrases.
+
+#### `summaryLength` - `number` - (optional)
+Number of sentences in the summary. Default is 2.
+
+#### `summaryPercentage` - `number` - (optional)
+Percentage of content to include in summary.
+
+## Usage
+
+**install**
+```bash
+npm install @flatfile/plugin-enrich-summarize
+```
+
+**import**
+```javascript
+import { FlatfileListener } from "@flatfile/listener";
+import { summarize } from "@flatfile/plugin-enrich-summarize";
+```
+
+**listener.js**
+```javascript
+const listener = new FlatfileListener();
+
+listener.use(
+  summarize({
+    sheetSlug: "articles",
+    contentField: "full_text",
+    summaryField: "summary",
+    keyPhrasesField: "key_phrases",
+    summaryLength: 3
+  })
+);
