  • Integrated documentation and package management: The site combines the package management (currently with a new central documentation source (codenamed '') for all 14000+ opam packages directly within the site.

  • Responsive and accessible: The site design also takes into account modern web-design principles, restructuring the old content in accordance with methods that will present it more compellingly. It is a total redesign that modernises the look and feel of the webpage, as well as make it easier to navigate, and more accessible (particularly on mobile devices).

  • Separation of data editing from HTML/CSS generation: The data used in the website is stored in Yaml or Markdown so users can easily edit it and contribute to the website. We generate OCaml code from this data to serve the site content and and Ocurrent to automate the data pipelines. All the data used in the site can be found in ./data.
