+## Sending SOL tokens
+You can send SOL from your Trust Wallet to any other valid address on the Solana
+network.  Once you know the other party's receiving address,
+go to the main page of the wallet from which you want to send some SOL tokens:
+ - Tap the "Solana" icon.
+ - Tap "Send"
+ - Under "Recipient Address":
+   - If you already have the receiving address you are going to send to,
+   tap "Paste"
+   - If you are transferring to another Trust Wallet user, you can use the apps'
+   QR code reader by tapping the square icon to the right of the "Paste" button.
+ - Under "Amount", enter the amount of SOL you want to send, or tap "Max"
+   to send **all** of the SOL in your wallet to the new address
+ - Tap "Next" to view a summary/confirmation page to review before submitting
+  the transaction
+    - The real-time network transaction fee will be shown.  This fee will be
+    paid by the sending account in addition to the full amount transferred.
+      - If you chose to send all your tokens to the new address by selecting
+      "Max" under amount, the amount sent to the recipient will be the account
+      balance *minus* the current network transaction fee.
+    - **Make sure you entered the "To" address correctly and that it matches your
+    desired wallet's receiving address!**
+ - Tap "Send" to submit the transaction.  The transaction will show as "Pending"
+ for a few seconds, and then will show as "Sent".

+## Using Multiple Wallet Addresses
+Trust Wallet allows you to create multiple wallets, each of which is
+secured by a different set of random seed words.  If you want to use more than
+one Solana address, follow these steps.
+
+#### Create an additional wallet
+ - In the main page of the Trust Wallet App, tap "Settings" in the bottom-right
+ corner.
+ - Tap "Wallets"
+ - Tap "+" to create a new Wallet
+ - Follow the steps above to add SOL tokens to your new wallet
+
+*Note: In the "Wallets" page under "Settings" you can re-name each of your wallets.
+ Consider giving each a descriptive name if you are planning to use your wallets
+ for different purposes, so you don't mistake one for the other.*
+
+#### Transferring SOL between your wallets
+Just like you can transfer SOL to another party, you can transfer SOL between
+wallets that you own.
+
+ - Copy the receive address of your **newly created** wallet.
+   - Make sure your **new** wallet is selected by going to
+   "Settings" --> "Wallets", then tap on the name of your new wallet.
+   - Tap the "Solana" icon.
+   - Tap "Receive" then tap "Copy".
+ - Select your previous/original wallet which already has some SOL by going to
+ "Settings" --> "Wallets", then tap on the name of your **original** wallet.
+   - Now follow the same process for [sending SOL tokens](#sending-sol-tokens)
+    using your **new** wallet's receiving address as the address in the "To"
+    field when you make the transfer.
