 # @polkadot/wasm-crypto
 
 Wrapper around crypto hashing functions
+
+## Usage
+
+Install the package (also requires `@polkadot/util` for `TextEncoder` polyfills - not included here as a dependency to keep the tree lean)
+
+`yarn add @polkadot/wasm-crypto @polkadot/util`
+
+Use it -
+
+```js
+const { u8aToHex } = require('@polkadot/util');
+const { bio39Generate, bip39ToSeed, waitReady } = require('@polkadot/wasm-crypto');
+
+async function main () {
+  // first wait until the WASM has been loaded (async init)
+  await waitReady();
+
+  // generate phrase
+  const phrase = bip39Generate();
+
+  // get ed25519 seed from phrase
+  const seed = bip39ToSeed(phrase);
+
+  // display
+  console.log('phrase:', phrase);
+  console.log('seed:', u8aToHex(seed));
+}
+```
