+### Ruby Version Management
+
+This project uses Ruby 3.4.1. We recommend using rbenv for managing Ruby versions. The `.ruby-version` file in the repository root will automatically configure rbenv to use the correct Ruby version.
+
+If you don't have rbenv installed, see `Ruby-on-Rails-install.md` for detailed installation instructions.
