Welcome to the documentation for SH, a domain-independent system for hierarchical planning, specifically state-based Hierarchical Task Network (HTN) planning. This documentation provides guidelines on setting up and utilizing SH in both developer and integration modes. For an in-depth understanding of the foundations, concepts, and algorithms of SH, we recommend checking the following literature:
