+Prices web service (web-price)
+===================================
 
+Web service for obtaining the price of a product given a date, the product id and the brand id.

+1. Local installation of the project
+    ```
+    mvn clean install
+    ```
+2. Run the app from the project root with:
+    ```
+    mvn clean spring-boot:run -pl boot -Dspring-boot.run.profiles=local
+    ```
+   or navigating to the `boot` directory of the project:
+    ```
+    mvn clean spring-boot:run -Dspring-boot.run.profiles=local
+    ```
+3. Service should be ready to receive requests at http://localhost:8080/price with OpenAPI docs available at http://localhost:8080/swagger-ui/index.html
+
+## Running Tests
