+# Visualised import graph
+
+## Instructions
+
+To test this, place a file `imports.gexf` inside this directory. You can create such a file with
+
+```
+lake exe graph html-template/imports.gexf
+```
+
+Then open `index.html` in any browser and you should see the graph.
+
+## Development
+
+Currently `lake exe graph output.html` will use the files here to create a stand-alone
+HTML file. It does so by search-replacing the JS-scripts, the `fetch('imports.gexf')`
+statement, and the `<h1>` header.
+
+Therefore any modifications to these lines need to be reflected in `ImportGraph/Cli.lean`!
