 ### UML diagram of software
 
 At the lowest level of our system we are showing how the software is designed. This is shown as a UML diagram. The diagram is made with mermaid. This shows the work flow of the different parts of the software which is running on the main server, for which we are using a Raspberry pi. The pi is located on the 6th floor of the school building in a locked server room.
