-# Your Sovran SystemsOS Magic Keys! 🗝️
-
-Welcome to your new computer! We have built a lot of cool secret forts (services) for you. To get into your forts, you need your magic keys (passwords).
-
-Here are all of your keys in one place. **Keep this document safe and do not share it with strangers!**
-
-> **How this document works:** This PDF is automatically generated by your computer. If any of your passwords, services, or connection details change, this document will automatically update itself within a few minutes. You can always find the latest version right here in your Documents folder. If you accidentally delete it, don't worry — your computer will recreate it for you!
-
-## 🖥️ Your Computer
-These are the master keys to the actual machine.
-
-### 1. Main Screen Unlock (The 'free' account)
-When you turn the computer on, it usually logs you in automatically. However, if the screen goes to sleep, or **if you enable Remote Desktop (RDP)**, you will need this to log in:
-- **Username:** \`free\`
-- **Password:** \`$FREE_PASS\`
-
-🚨 **VERY IMPORTANT:** You MUST write this password down and keep it safe! If you lose it, you will be locked out of your computer!
-
-### 2. The Big Boss (Root)
-Sometimes a pop-up box might ask for an Administrator (Root) password to change a setting. We created a super-secret password just for this!
-- **Root Password:** \`$ROOT_PASS\`
-
-### 3. The Hacker Terminal (\`ssh root@localhost\`)
-Because your main account is so safe, you cannot just type normal commands to become the boss. If you open a black terminal box and want to make big changes, you must use your special factory key!
-
-Type this exact command into the terminal:
-\`ssh root@localhost\`
-
-When it asks for a passphrase, type:
-- **Terminal Password:** \`gosovransystems\`

-## ⚡ Your Bitcoin & Lightning Node
-Your computer is a real Bitcoin node! It talks to the network secretly using Tor. Here is how to connect your wallet apps to it:
-
-### 1. Ride The Lightning (RTL)
-*This is the control panel for your Lightning Node.*
-Open the **Tor Browser** and go to this website. Use this password to log in:
-- **Website:** \`http://$RTL_ONION\`
-- **Password:** \`$RTL_PASS\`
-
-### 2. Electrs (Your Private Bank Teller)
-*If you use a wallet app on your phone or computer (like Sparrow or BlueWallet), tell it to connect here so nobody can spy on your money!*
-- **Tor Address:** \`$ELECTRS_ONION\`
-- **Port:** \`50001\`
-
-### 3. Bitcoin Core
-*This is the heartbeat of your node. It uses this address to talk to other Bitcoiners securely.*
-- **Tor Address:** \`$BITCOIN_ONION\`
