-# titan.github.io
-Unified token and contract list for Titan Mainnet and other Titan Chains.
+# @titan/github
+
+The `@titan/github` package provides a collection of tools for efficiently interacting with the Titan network.  
+It achieves this by providing a unified token and contract list for Titan and other chains.
+
+## Installation
+
+```
+npm install @titan/github
+```
+
+## Quickstart Recipes
+
+- Get all token data on each network
+
+```javascript
+import { TitanSDK } from '@titan/github'
+
+const sdk = new TitanSDK({
+  chainId: 55004,
+})
+const tokenList = sdk.tokens
+// Output the structure of the tokenList
+console.log('Token List:', tokenList)
+
+/*
+The structure of the tokenList
+tokenList =  [
+  {
+    chainId: 55004,
+    address: '0x7c6b91D9Be155A6Db01f749217d76fF02A7227F2',
+    name: 'Tokamak Network Token',
+    symbol: 'TON',
+    decimals: 6,
+    logoURI: 'https://titan.github.io/data/TON/logo.svg',
+    extensions: {
+      bridgeAddress: '0x4200000000000000000000000000000000000010',
+      titanListId: 'default',
+      titanTokenId: 'TON'
+    }
+  },
+  {
+    chainId: 55004,
+    address: '0x0000000000000000000000000000000000000000',
+    name: 'Ether',
+    symbol: 'ETH',
+    decimals: 18,
+    logoURI: 'https://titan.github.io/data/ETH/logo.svg',
+    extensions: {
+      bridgeAddress: '0x4200000000000000000000000000000000000010',
+      titanListId: 'default',
+      titanTokenId: 'ETH'
+    }
+  },
+  ... more token comes 
+]
+*/
+```
+
+- Get a token contract
+
+```javascript
+import { TitanSDK } from '@titan/github'
+
+const sdk = new TitanSDK({
+  chainId: 55004,
+})
+const TON_CONTRACT = sdk.getTokenContract('TON')
+const totalSupply = await TON_CONTRACT.totalSupply()
+console.log('totalSupply :', totalSupply)
+// totalSupply : BigNumber { _hex: '0x24d826680754da71d432', _isBigNumber: true }
+```
+
+- Get a contract instance
+
+```javascript
+import { TitanSDK } from '@titan/github'
+
+const sdk = new TitanSDK({
+  chainId: 55004,
+})
+const L2StandardBridge = sdk.getContract('L2StandardBridge')
+const L2Messenger = await L2StandardBridge.messenger()
+console.log('L2Messenger : ', L2Messenger)
+// L2Messenger : 0x4200000000000000000000000000000000000007
+```
+
+## Example using CodeSandbox
+
+You can try out the @titan/github package in an online environment using CodeSandbox. Click the button below to open the project in CodeSandbox:
+
+[![Open in CodeSandbox](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/github/your-username/your-titan-sdk-project)
+
+This CodeSandbox project includes a basic setup with the @titan/sdk package. You can explore and experiment with the functionalities in a live environment.
+
+## Contributing
+
+- If you want to add a token or change to the token list, refer to [the contracts documentation]("https://github.com/tokamak-network/titan.github.io/blob/main/tokens/README.md).

+## Production branch
+
+The production branch is "main". This branch holds the codebase for the most recent "stable" releases. Any changes made to the main branch are initially integrated from the develop branch.
+
+## Development branch
+
+The primary development branch is "develop". The develop branch includes the latest software version that remains compatible with the most recent experimental network deployments. If you're implementing a change that maintains backward compatibility, please submit your pull request to the develop branch.
