Hugo Progression is a Hugo template that can render progression frameworks using the same data format as the Monzo progression framework. A progression framework (or competency matrix, career ladder, career pathway) is a tool to help people within an organisation understand where they currently are and how to progress and grow in their work. It also helps an organisation map people’s competencies (their skills and knowledge) to compensation (how they’re rewarded for them financially) - find out more information in this blog post or on GitHub

It then converts those bookmarks to markdown and outputs them to the terminal. I use this tool to build regular newsletters for the backend developers at Crunch and to generate my Geek Reads posts
