 # 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

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
+#
