 ### Custom templates {#custom-templates}
 
 If you want to use custom templates with `blitz generate` instead of the
-default ones (e.g. with different styles), you can provide a path to the
-local directory with template files. You can specify it in your
-`blitz.config.ts` file. [Read more here](/docs/blitz-config#codegen). -->
+default ones (e.g. with different styles). You can specify it in your `app/blitz-server` 
+file by exporting the `cliConfig` object
+
+```ts
+import type { BlitzCliConfig } from "blitz"
+...
+export const cliConfig: BlitzCliConfig = {
+  customTemplates: "app/templates",
+}
+```
+
+#### Generate custom templates
+
+```bash
+blitz generate custom-templates
+```
+The above command will generate the default templates used by blitz to a directory of your choosing in order 
+to provide a starting point to use this feature. It will also update the `cliConfig` configuration, in the `app/blitz-server` file, 
+with the latest data to allow immediate usage.
