-/// AEON.py is a library...
+/// AEON.py is a Python library for working with Boolean networks. It supports a wide
+/// range of features, including symbolic representation of network dynamics. More general
+/// information is available on [GitHub](https://github.com/sybila/biodivine-aeon-py/).
+///
+/// To explore the library documentation, you can start with one of the core data classes:
+/// `RegulatoryGraph`, `BooleanNetwork` and `AsynchronousGraph`. Alternatively, to learn more about the available
+/// algorithms, you may want to look at `Attractors`, `TrapSpaces`, `FixedPoints`, `Classification`,
+/// or `Control`.
