+# @webassemblyjs/wasm-parser
+
+> WebAssembly binary format parser
+
+## Installation
+
+```sh
+yarn add @webassemblyjs/wasm-parser
+```
+
+## Usage
+
+```js
+import { decode } from "@webassemblyjs/wasm-parser";
+import { readFileSync } from "fs";
+
+const binary = readFileSync("/path/to/module.wasm");
+
+const decoderOpts = {};
+const ast = decode(binary, decoderOpts);
+```
+
+### Decoder options
+
+- `dump`: print dump information while decoding (default `false`)
+- `ignoreCodeSection`: ignore the code section (default `false`)
+- `ignoreDataSection`: ignore the data section (default `false`)
