+    ### deep
+
+    Use `--deep` to enable deep generation mode, which is required for SDK generation with the latest CLI version. This flag ensures that all nested types and dependencies are fully resolved during generation.
+
+    ```bash
+    # Generate SDK with deep mode
+    fern generate --deep --group ts-sdk
+
+    # Generate with deep mode and API specification
+    fern generate --deep --group ts-sdk --api your-api-name
+    ```
+
     ### 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
-    
+    fern generate --deep --preview
+
     # Preview specific SDK group
-    fern generate --group python-sdk --preview
+    fern generate --deep --group python-sdk --preview
     ```
 
     ### group
 
     Use `--group <group>` to filter to a specific group within `generators.yml`. Required unless you have a `default-group` declared.
 
     ```bash
-    fern generate --group internal
+    fern generate --deep --group internal
     ```
 
     ### api
 
     Use `--api <api>` to specify the API for SDK generation.
 
     ```bash
-    fern generate --api public-api
+    fern generate --deep --api public-api
     ```
 
     ### version
 
     Use `--version` to specify a version for SDKs and documentation. Adherence to [semantic versioning](https://semver.org/) is advised.
 
     ```bash
-    fern generate --version 2.11
+    fern generate --deep --version 2.11
