+# Rex-EMoolator
+
+Unofficial documentation of the **Piklib** and **BlooMoo** scripting engines used by the *Reksio's Adventures* game series, and of the **Rex-EMoolator** emulator.
+
+## What you'll find here
+
+- the structure of the engine's scripting language,
+- the data types and objects available to scripts,
+- the methods, fields, and signals exposed by each type,
+- how the engine interprets files, the loading order, and the data formats.
+
+## Navigation
+
+- [Engine](engine/index.md) — the scripting language, execution model, events, globals, and non-standard behaviours.
+- [Type reference](reference/index.md) — alphabetical list of types available in scripts.
+
+## Status
+
+This documentation is a work in progress. Much of it is derived from analysis of the original scripts and engine reverse-engineering; behaviour that has not yet been confirmed is annotated accordingly.
