+# Cardano Wallet
+
+This is a new version of the Cardano Wasm binding for Icarus/Yoroi.
+It exposes everything one needs to be able to build a cardano wallet
+in javascript.
+
+# How to install
+
+```
+npm i --save cardano-wallet
+```
+
+# How to use
+
+You can seek documentation
+[here](https://github.com/rustwasm/create-wasm-app#create-wasm-app)
+regarding how to use this package in your project.
+
+Now remember, with great power comes great responsibility. You can now
+write a cardano wallet, redeem your certificates, create and sign
+transactions.
+
+```js
+import * as Cardano from "cardano-wallet";
+
+const MNEMONICS = "crowd captain hungry tray powder motor coast oppose month shed parent mystery torch resemble index";
+const PASSWORD = "Cardano Rust for the winners!";
+
+// to connect the wallet to mainnet
+let settings = Cardano.BlockchainSettings.mainnet();
+
+// recover the entropy
+let entropy = Cardano.Entropy.from_english_mnemonics(MNEMONICS);
+// recover the wallet
+let wallet = Cardano.Bip44RootPrivateKey.recover(entropy, PASSWORD);
+
+// create a wallet account
+let account = wallet.bip44_account(Cardano.AccountIndex.new(0 | 0x80000000));
+let account_public = account.public();
+
+// create an address
+let key_pub = account_public.address_key(false, Cardano.AddressKeyIndex.new(0));
+let address = key_pub.bootstrap_era_address(settings);
+
+console.log("Address m/bip44/ada/'0/0/0", address.to_base58());
+```
