+# README
+
+This template is designed for personal use and open-source projects. It provides a quick start for Rails applications with essential features pre-configured, requiring minimal setup.
+
+- **Database**: SQLite3 for simplicity and ease of setup
+- **Defaults**:
+  - Solid Cache for efficient caching
+  - Solid Queue for background job processing
+  - Solid Cable for real-time features
+- **Frontend**:
+  - Tailwind CSS for rapid, utility-first styling
+  - Importmap for managing JavaScript modules
+- **Authentication**: Google OAuth integration for secure user sign-in
+
+[Learn more about Rails application templates](https://guides.rubyonrails.org/rails_application_templates.html)
+
+
+## Usage
+```sh
+rails new <app_name> -j importmap -c tailwind -d sqlite3 -m https://raw.githubusercontent.com/bastos/rails-template/refs/heads/main/template.rb
