 ## Usage
 To use pyUsadel, simply import the library in your Python script and you can access the functions and classes provided by pyUsadel to build and run your simulations. Some example simulations are included in under the folder `doc/examples/.`
 
+## Generating documentation
+The repository includes a helper script for building API documentation with [pdoc](https://pdoc.dev/). Install the optional documentation dependency and run the generator from the repository root:
