+# Code configuration
+
+For capstone project I made some changes in this code base. Mainly in Dockerfile.
+
+Also I learned how to use MySQL for spring petclinic - it reqiures some enviroment variables:
+
+* MYSQL_USER
+* MYSQL_PASSWORD
+* MYSQL_ROOT_PASSWORD
+* MYSQL_DATABASE
+* MYSQL_URL
+
+They are needed for conenction to RDS. One can use it via `docker -e MYSQL_...` or `export MYSQL_...` (for `java -jar` usage).
