 # ao-tokens
 
 This library makes it easy to interact with tokens and operate with token quantities.
+
+## Installation
+
+The library needs `@permaweb/aoconnect` as a peer dependency.
+
+```sh
+npm i ao-tokens @permaweb/aoconnect
+```
+
+```sh
+yarn add ao-tokens @permaweb/aoconnect
+```
+
+## Usage
+
+### Tokens
+
+The `Token` class provides basic methods to query token data. It first needs to be loaded:
+
+```ts
+// load CRED
+const aoCredToken = await Token(
+  // id of the token
+  "Sa0iBLPNyJQrwpTTG-tWLQU-1QeUAJA73DdxGGiKoJc"
+);
+```
+
+You can also provide custom configuration for this:
+
+```ts
+const aoCredToken = await Token(
+  // id of the token
+  "Sa0iBLPNyJQrwpTTG-tWLQU-1QeUAJA73DdxGGiKoJc",
+  // custom signer (default is window.arweaveWallet)
+  createDataItemSigner(wallet),
+  // custom aoconnect instance
+  connect({ ... })
+);
+```
+
+#### Token info
+
+Information about the token, such as `Name`, `Ticker`, `Denomination`, etc. is preloaded:
+
+```ts
+const tokenID = aoCredToken.id;
+const tokenName = aoCredToken.info.Name;
+const symbol = aoCredToken.info.Ticker;
+const denomination = aoCredToken.info.Denomination;
+const logo = aoCredToken.info.Logo;
+```
+
+#### Wallet balance
+
+You can query the token balance for an address. This will return a `Quantity` instance.
+
+```ts
+const balance = await aoCredToken.getBalance(
+  // wallet address
+  "HjvCPN31XCLxkBo9FUeB7vAK0VCfSeY52-CS-6Iho8l"
+);
+
+// prints something like: "1,345.87"
+console.log("Your balance is:", balance.existingBal.toLocaleString());
+```
+
