+- [handbook.md](./handbook.md) — Comprehensive handbook for the Fun language and VM: install/build, configuration flags, usage, and full feature overview.
+- [types.md](./types.md) — Core types (numbers, strings, arrays, maps, nil/bool), common operations, patterns, and interop notes.
+- [includes.md](./includes.md) — Using local vs. system includes, FUN_LIB_DIR, DEFAULT_LIB_DIR, and namespaced includes with `as`.
+- [repl.md](./repl.md) — REPL guide: how to build/launch, editing and history, completions, REPL‑on‑error, and tips.
+- [opcodes.md](./opcodes.md) — VM opcodes overview grouped by domain with brief behavior/stack notes.
+- [internals.md](./internals.md) — Implementation details: bytecode format, VM architecture, stacks/frames, parser, and dispatch.
+- [rust.md](./rust.md) — Writing Rust‑backed opcodes and wiring them into the C VM; build/setup notes.
+
+## Tips
+
+- When building from the repo without installing, set `FUN_LIB_DIR` to the local `./lib` directory so examples and the REPL can locate the stdlib.
+- For a broader project overview and quickstart, see the repository root [README.md](../README.md).
