-A SpiderBasic wrapper for WaveSurfer
+A SpiderBasic wrapper for [wavesurfer.js v7](https://wavesurfer.xyz) — audio waveform visualization and playback.
+
+This is rough and partially untested. It covers the core API (create, load, play, pause, seek, zoom, events…) and three plugins: **Timeline**, **Minimap**, and **Spectrogram**. Other plugins can be loaded via the generic `RegisterPlugin()` procedure.
+
+## Quick Start
+
+```spiderbasic
+IncludeFile "WaveSurferSB/WaveSurferSB.sbi"
+
+Procedure OnLoaded(Success)
+  If Success
+    Global ws = WaveSurferSB::Create("#waveform", WaveSurferSB::#DragToSeek)
+    WaveSurferSB::TimelineCreate(ws)
+    WaveSurferSB::Load(ws, "audio.mp3")
+  EndIf
+EndProcedure
+
+WaveSurferSB::Download(@OnLoaded(), "timeline")
+```
+
+## Files
+
+- `WaveSurferSB.sbi` — the module
+- `WaveSurferSB_Plugins_Example.sb` — working example with all three plugins
+
+## Notes
+
+- Handles the AMD/UMD conflict with SpiderBasic's Dojo runtime automatically
+- Loads from unpkg CDN by default; pass `UseLocalFiles = #True` to load from `LocalFiles/JS/`
+- Each plugin procedure has a simple form and an `_ex` form accepting raw JSON options
