 # VPR-Backend
+This project includes the backend for the VPR-project.
 
+# Installation and Getting Started
+- To run the server you first have to install a MySQL database. 
+> For example MariaDB (https://mariadb.com/downloads/)
+
+- Then you have to create a the database with the "create VPR-DB.sql"-file.
+
+- Create a new user for the db e.g. named "springuser"
+> The database should only be reachable from localhost to improve the security!
+
+- Next create a "application.properties"-file in "vpr/src/main/resources". It should contain following content:
+``` 
+# "update" will automatically get the db-structure
+# It can be "none", "update", "create", or "create-drop", but you have to start with "create" or "update" and should use "none" in production(for security).
+# see https://docs.jboss.org/hibernate/orm/5.4/userguide/html_single/Hibernate_User_Guide.html#configurations-hbmddl for more information.
+spring.jpa.hibernate.ddl-auto=update
+
+# Specify the database address, port and name
+spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/vpr
+
+# Add the login-data
+spring.datasource.username=<USERNAME>
+spring.datasource.password=<PASSWORD>
+
+spring.datasource.driver-class-name =com.mysql.jdbc.Driver
+#spring.jpa.show-sql: true
+``` 
+
+You should now be able to start the application :D
