 ### Auto Selecting a Wallet

+A common UX pattern is to remember the last wallet that a user has previously connected by storing it in localStorage and then automatically selecting them for the user next time they visit your app.
+You can enable this in your app by using the `autoConnectLastWallet` parameter when initializing and Onboard will take care of it:
 
 ```javascript
-const walletsSub = onboard.state.select('wallets')
-const { unsubscribe } = walletsSub.subscribe((wallets) => {
-  const connectedWallets = wallets.map(({ label }) => label)
-  window.localStorage.setItem('connectedWallets', JSON.stringify(connectedWallets))
+const onboard = Onboard({
+  // ... other options
+  connect: {
+    autoConnectLastWallet: true
+  }
 })
-
-// Don't forget to unsubscribe when your app or component un mounts to prevent memory leaks
-// unsubscribe()
-```
-
-Now that you have the most recent wallets connected saved in local storage, you can auto select those wallet(s) when your app loads:
-
-```javascript
-const previouslyConnectedWallets = JSON.parse(window.localStorage.getItem('connectedWallets'))
-
-if (previouslyConnectedWallets) {
-  // Connect the most recently connected wallet (first in the array)
-  await onboard.connectWallet({ autoSelect: previouslyConnectedWallets[0] })
-
-  // You can also auto connect "silently" and disable all onboard modals to avoid them flashing on page load
-  await onboard.connectWallet({
-    autoSelect: { label: previouslyConnectedWallets[0], disableModals: true }
-  })
-
-  // OR - loop through and initiate connection for all previously connected wallets
-  // note: This UX might not be great as the user may need to login to each wallet one after the other
-  // for (walletLabel in previouslyConnectedWallets) {
-  //   await onboard.connectWallet({ autoSelect: walletLabel })
-  // }
-}
 ```

+### Standalone Usage
+
+
+To use the Transaction Preview package without web3-onboard all a developer needs to do is: 
+- Execute the entry function from the `@web3-onboard/transaction-preview` package and optional params
+- Run the returned `init` function with their [Blocknative API key](https://onboard.blocknative.com/docs/overview/introduction#optional-use-an-api-key-to-fetch-real-time-transaction-data-balances-gas), an initialized instance of their [Blocknative SDK](https://www.npmjs.com/package/bnc-sdk) and a containerElement string with the html ID of the target element to append the visualization to
+- Finally pass a transaction meant for a wallet provider (created using libraries like Ethers or Web3)
+
+With the above steps a UI will be rendered with the balance changes and gas used.
+```typescript
+import transactionPreviewModule from '@web3-onboard/transaction-preview'
+
+const {init, previewTransaction} = transactionPreviewModule({
+  // Optional: Require balance change approval prior to sending transaction to wallet
+  // Defaults to true
+  // requireTransactionApproval?: false
