+# Project: RuoYi
+
+## Project Overview
+
+This project, RuoYi, is a Java-based rapid development platform with a separate frontend and backend.
+
+**Backend:**
+*   **Framework:** Spring Boot
+*   **Security:** Spring Security, JWT
+*   **Database:** The presence of `pom.xml` and `ry_*.sql` files suggests a relational database like MySQL.
+*   **Modules:** It's a multi-module Maven project, including `ruoyi-admin`, `ruoyi-framework`, `ruoyi-system`, `ruoyi-quartz`, `ruoyi-generator`, and `ruoyi-common`.
+*   **Key Technologies:** Redis, Druid connection pool, PageHelper for pagination.
+
+**Frontend:**
+*   **Framework:** Vue.js 2
+*   **UI Library:** Element UI
+*   **Build Tool:** vue-cli
+
+## Building and Running
+
+### Backend
+
+The backend is a standard Maven project.
+
+**Build:**
+To build the entire project, run Maven's `package` goal from the root directory:
+```bash
+mvn package
+```
+
+**Run:**
+The `ry.sh` script is provided to manage the application. To run the application, you can use the following command from the root directory:
+
+```bash
+# Make sure the script is executable
+chmod +x ry.sh
+
+# Start the application
+./ry.sh start
+```
+This will start the `ruoyi-admin.jar`.
+
+To stop the application:
+```bash
+./ry.sh stop
+```
+
+### Frontend
+
+The frontend is a Vue.js project located in the `ruoyi-ui` directory.
+
+**Install Dependencies:**
+Navigate to the `ruoyi-ui` directory and install the dependencies. The `pnpm-lock.yaml` file suggests `pnpm` is the preferred package manager.
+
+```bash
+cd ruoyi-ui
+pnpm install
+```
+
+**Run in Development Mode:**
+```bash
+pnpm run dev
+```
+
+**Build for Production:**
+```bash
+pnpm run build:prod
+```
+
+## Development Conventions
+
+*   **Backend:** The project follows standard Maven project structure and conventions. It is a multi-module project.
+*   **Frontend:** The frontend uses Vue.js with single-file components (`.vue` files). The `package.json` file defines scripts for common tasks.
+*   **Database:** SQL migration scripts seem to be located in the `sql` directory.
+*   **Code Generation:** The project includes a `ruoyi-generator` module, which can be used to generate boilerplate code.
