en is a tool to write non-linear, connected pieces of text and have their references mapped out as a graph of connected information.
It works by ingesting a TOML file containing your node specification and serving it as a website that allows nodes to be browsed, searched and listed in relation to each other or as a shallow tree of nodes.
For an outline of planned and completed features, see the roadmap.
You can learn more and see what en looks like by visiting the homepage, which is rendered using en itself.
