Follow the tutorials in this order to build up from Prolog fundamentals to distributed and concurrent systems.
1. Start with n1
Learn the core Prolog interaction model through the tutorial in the Examples drawer. It is the best place to get comfortable with queries, facts, rules, state, and the limits—and benefits—of stateless calls.
2. Continue with n2
Explore the distributed ISOTOPE examples. They introduce communication between nodes and show why a distributed model is useful once a single query is no longer enough.
3. Continue with n3 or n4
Visit either node for the complete actor tutorial: messaging, servers, supervisors, statecharts, and fault handling. They contain the same actor material, so one is sufficient.
4. Run SWI-WASM against the nodes
Open a node’s Demonstrator and select SWI-WASM. The tutorial then runs in the browser, while examples that use node URLs can still call n1–n4. Browser runtime state is local to the tab and is reset by a refresh.
