+This package contains a JS code transpiler with a plugin system that can be used to transform the code.
+
+A plugin can be registered via a `registerTranspilerPlugin` call :

+```js
+registerTranspilerPlugin({
+  walk: (context) => ({
+    enter: function(node, parent, prop, index) {},

+
+where the enter/leave functions (both optional) follow the `estree-walker` walk API.
+
+4 plugins are currently hosted inside `@strudel/transpiler`
+
+- mini: add locations of mini notation strings (double quoted or backticked) for highlighting
+- widgets: add handling of sliders & draw widgets
+- sample: make it possible to call a sample without await
+- kabelsalat: transform the code to handle the `K(..)` kabelsalat notation
+
+it also
 
-- add locations of mini notation strings (double quoted or backticked) for highlighting
-- converts pseudo note variables to note strings
 - adds return statement to the last expression
+- handles label capturing for block-based eval
