+# Amaro
+
+Amaro is a wrapper around `@swc/wasm-typescript`, a WebAssembly port of the SWC TypeScript parser.
+It's currently used as an internal in Node.js for [Type Stripping](https://github.com/nodejs/loaders/issues/208), but in the future it will be possible to be upgraded separately by users.
+The main goal of this package is to provide a stable API for TypeScript parser, which is unstable and subject to change.
+
+> Amaro means "bitter" in Italian. It's a reference to [Mount Amaro](https://en.wikipedia.org/wiki/Monte_Amaro_(Abruzzo)) on whose slopes this package was conceived.
+
+## How to Install
+
+To install Amaro, run:
+
+```shell
+npm install amaro
+```
+
+## How to Use
+
+By default Amaro exports a `transformSync` function that performs type stripping.
+Stack traces are preserved, by replacing removed types with white spaces.
+
+```javascript
+const amaro = require('amaro');
+const { code } = amaro.transformSync("const foo: string = 'bar';");
+console.log(code); // "const foo         = 'bar';"
+```
