+description: >-
+  A tool that helps developers to understand and maintain their software architecture.
+  It generates interactive, configurable dependency graphs out of source code, with all packages and modules included.
+  You can choose the level of details and get what portions of your codebase gets rendered.
+  That way you get a quick understanding of the software's architecture and detect unwanted dependencies and spaghetti code which harm efficient maintenance and leads to technical debt and inflexibility.
