 # Uploadcare Rails Example app
 
 This example project demonstrates the uploadcare-rails capabilities.
-The app is pinned to the `5-0-stable` branches of `uploadcare/uploadcare-rails` and `uploadcare/uploadcare-ruby`, targets Ruby `>= 4.0.0`, runs Rails `8.1.x`, and uses pnpm-managed Hotwire assets.
+The app uses the `5.0.0.rc1` prerelease gems for `uploadcare-rails` and `uploadcare-ruby`, targets Ruby `>= 4.0.0`, runs Rails `8.1.x`, and uses Hotwire with Tailwind CSS.

 **NOTE**
 
-The app now uses the current `5-0-stable` branch APIs. The Post and Comment forms render the v1 Uploadcare File Uploader Web Components directly with `<uc-form-input>`, `<uc-config>`, `<uc-file-uploader-regular>`, and `<uc-upload-ctx-provider>`. Group uploads submit a single Uploadcare group URL that matches `has_uploadcare_files`. Manual API actions in controllers use `Uploadcare::Rails.client`, and the conversion examples use the raw REST parity layer where exact path control is needed.
