+# Sistema de Mantenimiento
+
+This project can be used as a starting point to create your own Vaadin application with Spring Boot.
+It contains all the necessary configuration and some placeholder files to get you started.
+
+## Running the application
+
+The project is a standard Maven project. To run it from the command line,
+type `mvnw` (Windows), or `./mvnw` (Mac & Linux), then open
+http://localhost:8080 in your browser.
+
+You can also import the project to your IDE of choice as you would with any
+Maven project. Read more on [how to import Vaadin projects to different IDEs](https://vaadin.com/docs/latest/guide/step-by-step/importing) (Eclipse, IntelliJ IDEA, NetBeans, and VS Code).
+
+## Deploying to Production
+
+To create a production build, call `mvnw clean package -Pproduction` (Windows),
+or `./mvnw clean package -Pproduction` (Mac & Linux).
+This will build a JAR file with all the dependencies and front-end resources,
+ready to be deployed. The file can be found in the `target` folder after the build completes.
+
+Once the JAR file is built, you can run it using
+`java -jar target/sistema-mantenimiento-1.0-SNAPSHOT.jar`
+
+## Project structure
+
+- `MainLayout.java` in `src/main/java` contains the navigation setup (i.e., the
+  side/top bar and the main menu). This setup uses
+  [App Layout](https://vaadin.com/docs/components/app-layout).
+- `views` package in `src/main/java` contains the server-side Java views of your application.
+- `views` folder in `src/main/frontend` contains the client-side JavaScript views of your application.
+- `themes` folder in `src/main/frontend` contains the custom CSS styles.
+
+## Useful links
+
+- Read the documentation at [vaadin.com/docs](https://vaadin.com/docs).
+- Follow the tutorial at [vaadin.com/docs/latest/tutorial/overview](https://vaadin.com/docs/latest/tutorial/overview).
+- Create new projects at [start.vaadin.com](https://start.vaadin.com/).
+- Search UI components and their usage examples at [vaadin.com/docs/latest/components](https://vaadin.com/docs/latest/components).
+- View use case applications that demonstrate Vaadin capabilities at [vaadin.com/examples-and-demos](https://vaadin.com/examples-and-demos).
+- Build any UI without custom CSS by discovering Vaadin's set of [CSS utility classes](https://vaadin.com/docs/styling/lumo/utility-classes).
