+Mintlify supports versioning or localization. You can use one or the other, not both.

 These guides will assume `v1` pages are in a folder named `v1`, `v2` pages are in a folder named `v2`, and so on. While this method of structuring your files isn't strictly necessary, it's a great way to keep your files organized.

+## Localization
+
+### Setup
+
+`"versions"` in your `mint.json` can be leveraged to create different language versions by adding a `locale` value to the version. The first localization from the array serves as the default localization.
+
+We currently support localization in English (`en`), Chinese (`cn`), Spanish (`es`), French (`fr`), Japanese (`jp`), Portuguese (`pt`), and German (`de`).
+
+```json mint.json example
+"versions": [
+  {
+    "name": "English",
+    "locale": "en",
+  },
+  {
+    "name": "French",
+    "locale": "fr",
+  },
+  {
+    "name": "Spanish",
+    "locale": "es"
+  }
+]
+```
+
+<Tip>
+  The versions dropdown will show your localizations in the order you include
+  them in the `mint.json`.
+</Tip>
+
+Once setup, the rest of localization is handled by the versioning setup described above.
