+Fork repo, pull it and do next:
+
+
+```sh
 cd adminforth
 npm ci
 npm run build
 
-
 # this will install all official plugins and link adminforth package, if plugin installed it will git pull and npm ci
 npm run install-plugins

 - New users will have their email automatically confirmed (`email_confirmed = true`)

+### 4. Open Signup
+
+By default, users must exist in the system before they can log in with OAuth. You can enable automatic user creation for new OAuth users with the `openSignup` option:
+
+```typescript title="./resources/adminuser.ts"
+new OAuthPlugin({
+  // ... adapters configuration ...
+  openSignup: {
+    enabled: true,

+### 5. UI Customization
+
+You can customize the UI of the OAuth login buttons by using the `iconOnly` and `pill` options.
+
+```typescript title="./resources/adminuser.ts"
+new OAuthPlugin({
+  // ... adapters configuration ...
+  iconOnly: true, // Show only provider icons without text
+  pill: true, // Use pill-shaped buttons instead of rectangular
+}),
