 # Light Token Examples
-## Quickstart
 
-### [Devnet Quickstart](devnet-quickstart/)
+Light token is a high-performance token standard that reduces the cost of mint and token accounts by 200x.
 
-End-to-end example: create a mint, token account, mint tokens, and transfer on devnet.
+* All light mint and token accounts are on-chain accounts like SPL, but the light token program sponsors the rent-exemption cost for you.
+* Light-token accounts can hold balances from any light, SPL, or Token-2022 mint.
+* Light-mint accounts represent a unique mint and optionally can store token-metadata. Functionally equivalent to SPL mints.
 
-## Cookbook
+### Toolkits
 
-Step-by-step recipes for light-token on Devnet/Localnet.
+- **[Payments and Wallets](toolkits/payments-and-wallets/)** - All you need for wallet integrations and payment flows. Minimal API differences to SPL.
+- **[Streaming Tokens](toolkits/streaming-tokens/)** - Stream mint events using Laserstream
 
-### [Actions](cookbook/actions/)
+### TypeScript Client
 
--   **[create-mint](cookbook/actions/create-mint.ts)** - Create a new light-token mint
--   **[create-ata](cookbook/actions/create-ata.ts)** - Create an associated light-token account
--   **[load-ata](cookbook/actions/load-ata.ts)** - Load a cold token account (compressed) to hot balance (light-token ata)
--   **[mint-to](cookbook/actions/mint-to.ts)** - Mint tokens to a light-account
--   **[transfer-interface](cookbook/actions/transfer-interface.ts)** - Transfer tokens between light-token, T22, and SPL token accounts.
--   **[wrap](cookbook/actions/wrap.ts)** - Wrap SPL to light-token
--   **[unwrap](cookbook/actions/unwrap.ts)** - Unwrap light-token to SPL for off-ramps and legacy integrations
+TypeScript examples for light-token-sdk.
 
-### [Instructions](cookbook/instructions/)
-
-Low-level instruction builders:
-
--   **[create-mint](cookbook/instructions/create-mint.ts)** - Build create mint instruction

-### [Streaming Tokens](toolkits/streaming-tokens/)
-
-Rust program example with test to stream mint events of the Light-Token Program.
-
-
-## Setup
-
-```bash

-            @lightprotocol/compressed-token@alpha
-```
-
-```bash
-cp .env.example .env # ...and set RPC_URL
-```
-
-## Run
-
-From repo root:
-
-```bash
-# quickstart
-npm run quickstart
-
-# cookbook (local)
-npm run cookbook create-mint:action
-npm run cookbook compress:action
-# ... see cookbook/package.json for more
-
-# payments
-npm run toolkit:payments send-and-receive
-```

+
+Integration examples for wallets, payments, and streaming.
+
+### Payments and Wallets
+
+The Light-token API matches the SPL-token API almost entirely, and extends their functionality to include the light token program in addition to the SPL-token and Token-2022 programs.
+Your users hold and receive tokens of the same mints, just stored more efficiently. Get an overview [in the README](payments-and-wallets/README.md).
+- **[get-balance](payments-and-wallets/get-balance.ts)** - Fetch token balances
+- **[get-history](payments-and-wallets/get-history.ts)** - Fetch transaction history
+- **[send-and-receive](payments-and-wallets/send-and-receive.ts)** - Send and receive light-tokens
+- **[wrap](payments-and-wallets/wrap.ts)** - Wrap SPL/T22 to light-token
+- **[unwrap](payments-and-wallets/unwrap.ts)** - Unwrap light-token to SPL/T22
