The documentation of dynamic software systems like the microservice-based architecture is very difficult, because there are different stakeholders with various views, which have to be taken into account. Additionally, the documentation of a complete system is distributed across different system components. Because of that, it is necessary to automate the documentation of such dynamic software systems. This master thesis deals with the implementation of a tool, which keeps the documentation of a microservice-based software systems automatically up-to-date, and makes it possible to integrate information from external systems. At the beginning of this thesis, basic concepts of software architecture and software architecture documentation area are discussed. After that, the requirements for the documentation tool are defined. These requirements were determined using a literature research and a survey. Finally, the implemented dashboard for the documentation of microservice-based software systems is described.
