+# Configuration
+
+**docsify** supports two different ways of configuration. You can configure the `window.$docsify` or write configuration on the script tag via `data-*` attributes.
+
+```html
+<!-- by $docsify -->
+<script>
+  window.$docsify = {
+    repo: 'QingWei-Li/docsify',
+    maxLevel: 3,
+    coverpage: true
+  }
+</script>
+
+<!-- or data-* -->
+<script
+  src="//unpkg.com/docsify"
+  data-repo="QingWei-Li/docsify"
+  data-max-level="3"
+  data-coverpage>
+</script>
+```
+
+Both ways are compatible. However, the first way is recommended. It is clear and can be configured in a separate file.
+
+!> In `window.$docsfiy`, the options should be written by camelCase.
