+
+When using EC2 instances, by default you don't have root access, and Dokploy needs root access to install the necessary packages without restrictions.
+
+To do this, you need to make manual modifications to the instance:
+
+1. **Click on launch instance**
+
+2. **Select the distribution of your choice** (we recommend Ubuntu, Debian or Amazon Linux)
+
+3. **Choose your instance type** and all the other settings you want
+
+4. **In the Network settings**, click on:
+   - `Allow SSH traffic from the internet`
+   - `Allow HTTPS traffic from the internet` 
+   - `Allow HTTP traffic from the internet`
+
+5. **Click on `Launch instance`** (If you see a warning about adding a new key pair, just skip it)
+
+6. **Now go to your instance and click on `Connect`**
+
+7. **Type this command** `sudo nano /etc/ssh/sshd_config` and find the line `#PermitRootLogin prohibit-password` and change it to `PermitRootLogin yes`. Save and exit.
+
+8. **Restart the SSH service** by typing this command:
+   ```bash
+   sudo systemctl restart sshd
+   ```
+
+9. **Go back to the EC2 instance and click on `Connect`** but instead of using the default username `ec2-user`, type `root`
+
+10. **Connect using the `root` user**
+
+11. **Create a server in the Dokploy dashboard** in the remote server section
+
+12. **Specify the server details**:
+    - **IP field**: IPv4 public address of the instance
+    - **Username field**: `root`
+    - **SSH key**: Select the SSH key you created earlier
+    - Click on `Create Server`
+
+13. **Click on action `Setup Server`** in the `SSH Keys` tab, follow the manual process (Copy the Command and paste in the server manually)
+
+14. **Connect to the server** - you should now be able to setup the server properly and deploy your applications
