+      clang-uml is an automatic C++ to UML class, sequence, package and include diagram generator, driven by YAML configuration files.
+      The main idea behind the project is to easily maintain up-to-date diagrams within a code-base or document legacy code.
+      The configuration file or files for clang-uml define the types and contents of each generated diagram.
+      The diagrams can be generated in PlantUML, MermaidJS and JSON formats.
