+    ### deep
+
+    Use `--deep` to enable deep generation mode. This flag is recommended for the latest CLI version and ensures complete SDK generation.
+
+    ```bash
+    fern generate --deep --group ts-sdk
+    ```
+
     ### preview
 
     Use `--preview` to test SDK changes locally before publishing. This is especially useful during development:
     - Generates SDK into a local `.preview/` folder
     - Allows quick iteration on your Fern definition
     - No changes are published to package managers or GitHub
-

     ```bash
     # Preview all SDKs
     fern generate --preview
-    
+
     # Preview specific SDK group
     fern generate --group python-sdk --preview
     ```
