+## 🔌 Requirements
+
+- **[ClassicAPI](https://github.com/brues-code/ClassicAPI) — required.** This fork uses ClassicAPI for structured spell, cast, nameplate, bag, merchant and player-state data where it is more reliable than legacy tooltip/combat-log parsing. ShaguTweaks declares `!!!ClassicAPI` as a dependency and will not load without it.
+- **[SuperWoW](https://github.com/balakethelock/SuperWoW) — optional / recommended.** It remains supported as an additional compatibility source, especially for GUID-based cast information, but ClassicAPI is the primary API layer.
+
+Use the latest ClassicAPI version and follow its upstream installation instructions.
