# VS Code Remote SSH Setup Guide
<!-- 
Use this guide to connect your Company PC to the "Digital Fortress" (Synology Ubuntu VM).
-->

## 1. Install the Extension
1.  Open VS Code on your local PC.
2.  Go to the **Extensions** view (Square icon on the left).
3.  Search for **"Remote - SSH"** (by Microsoft).
4.  Click **Install**.

## 2. Configure the Connection
1.  Press `F1` (or `Ctrl+Shift+P`) to open the Command Palette.
2.  Type **"Remote-SSH: Open SSH Configuration File"**.
3.  Select the first option (usually `C:\Users\...\.ssh\config`).
4.  Add the following entry (replace with actual values):

```ssh
Host posimai-fortress
    HostName 100.x.y.z       # Tailscale IP of the Ubuntu VM
    User ubuntu              # Username on the VM
    # IdentityFile ~/.ssh/id_rsa  # Path to your private key (if used)
```
*Tip: Using the Tailscale IP (`100.x...`) is recommended as it works from anywhere (home or office).*

## 3. Connect!
1.  Click the green **"><"** icon at the very bottom-left corner of VS Code.
2.  Select **"Connect to Host..."**.
3.  Select **`posimai-fortress`**.
4.  A new VS Code window will open. It might ask for a password (if you haven't set up keys).
5.  Once connected, click **"Open Folder"** and navigate to `/home/ubuntu/dev/posimai/`.

## 4. Verify
*   Open the Terminal in VS Code (`Ctrl+J`).
*   Type `hostname`. It should say `ubuntu` (or whatever you named the VM), NOT your local PC name.
*   **Success!** You are now inside the Fortress. All code stays there.
