 # Quick Start Guide for Alby Hub
 
-1. **Launch Alby Hub**  
-   Click the `Launch UI` button to start Alby Hub.
+1. **Configure Alby Hub**
+   In the Alby Hub configuration settings, select your preferred Lightning implementation:
 
-2. **Get Started**  
-   On the Alby Welcome screen, click **Get Started (LND)**.
+   - **LND on this server**: This option tells Alby Hub to use the LND node installed on this StartOS server. It is the more sovereign and secure option, allowing full control over your node.
+   - **Alby Hub embedded light node**: This option tells Alby Hub to use its own, built-in light node. This option is convenient but offers less control over your node.
 
-3. **Create a Strong Password**  
-   Set a strong password for your Alby Hub account. It’s recommended to store this password securely in your self-hosted Vaultwarden.
+2. **Start the Service**
+   After configuring, start the Alby Hub service.
 
-4. **Connect Your Alby Account**  
+3. **Launch Alby Hub**  
+   Click the `Launch UI` button to open the Alby Hub interface.
+
+4. **Get Started**  
+   On the Alby Welcome screen, click the **Get Started** button. The button will display either (LND) or (LDK) based on your chosen configuration.
+
+5. **Create a Strong Password**  
+   Set a strong password for your Alby Hub account. It's recommended to store this password securely in your self-hosted Vaultwarden. If you are using the Alby Hub embedded light node, it is critical you do not lose your password, as it will result in loss of funds.
+
+6. **Connect Your Alby Account**  
    Follow the on-screen instructions to connect your Alby account.
 
-5. **All Set!**  
-   You’re done! Your Alby Hub is now ready to use.
+7. **All Set!**  
+   You're done! Your Alby Hub is now ready to use.
