 # Edit Link
 
-Documentation coming soon...
+Edit Link lets you display a link to edit the page on Git management services such as GitHub, or GitLab. To enable it, add `themeConfig.editLink` options to your config.
+
+```js
+export default {
+  themeConfig: {
+    editLink: {
+      pattern: 'https://github.com/vuejs/vitepress/edit/main/docs/:path'
+    }
+  }
+}
+```
+
+The `pattern` option defines the URL structure for the link, and `:path` is going to be replaced with the page path.
+
+By default, this will add the link text "Edit this page" at the bottom of the doc page. You may customize this text by defining the `text` option.
+
+```js
+export default {
+  themeConfig: {
+    editLink: {
+      pattern: 'https://github.com/vuejs/vitepress/edit/main/docs/:path',
+      text: 'Edit this page on GitHub'
+    }
+  }
+}
+```
