Documentation is an integral part of any development process and can take significant time and effort to write. Additionally, even if we write quality documentation, oftentimes it fails to evolve as development best practices change and can quickly become outdated. Mermaid aims to fix this so-called “Doc-Rot” by creating a quick and easy way to create detailed diagrams that can evolve alongside code development.

Mainframes have long powered critical financial transactions and government operations. However, across the U.S., particularly in Kansas, these systems are showing their age. The COVID-19 pandemic exposed a critical issue: essential services like unemployment insurance were crippled by outdated COBOL systems, causing significant delays.
