-# @strudel.cycles/transpiler
-
-This package contains a JS code transpiler with the following features:
-
- 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
-
-The transpiler is written with [acorn](https://github.com/acornjs/acorn) and aims to replace the `@strudel.cycles/eval` package, which uses [shift-ast](https://www.npmjs.com/package/shift-ast).
-
-## Install
-
-```sh
-npm i @strudel.cycles/transpiler
-```
-
-## Use
-
-```js
-import { transpiler } from '@strudel.cycles/core';
