-Deploy VM
----------
+This guide provides step-by-step instructions for deploying a VyOS instance with two NICs and the required resources on Google Cloud Platform (GCP).
 
-To deploy VyOS on GCP (Google Cloud Platform)
+Prerequisites
+========
 
-1. Generate SSH key pair type **ssh-rsa** from the host that will connect to
-   VyOS.
+Before proceeding, ensure the following:
+
+- A GCP account with billing enabled.
+- Permissions to deploy Marketplace images.
+- Access to enable APIs and create resources (e.g., Compute Engine Admin, Network Admin).
+- An SSH key pair for VyOS instance access.
+- GA Google Cloud Project.
+
+Deployment Steps
+========
+
+Step 1: Add SSH Key
+-------------------
+
+1. If you don’t already have SSH keys, generate an SSH key pair of type ``ssh-rsa`` on your local machine:

-.. note:: In name "vyos@mypc" The first value must be "**vyos**". Because
-   default user is vyos and google api uses this option.
+.. note:: In the comment ``vyos@mypc``, the username must start with vyos.
+         This is because the default user in the VyOS image is ``vyos``, and the Google Cloud API uses this value for SSH access.

+
+
+Step 3: Create VPC Networks and Subnets
+-------------------------------
+
+1. In the Google Cloud console **VPC Network > VPC Networks** https://console.cloud.google.com/networking/networks/list
+
+2. Select select a project.
+
+.. figure:: /_static/images/cloud-gcp-proj.png
+
+3. Click **Create VPC Network**.
+
+   **Public VPC**:
+
+   - Name: e.g., ``vyos-public-vpc``
+
+   - Subnet creation mode: ``Custom``
+
+   - Subnet name: e.g., ``vyos-public-subnet``
+
+   - Region: e.g., ``europe-west1``
+
+   - IP range: e.g., ``10.0.1.0/24``
+
+   - Leave all other settings at default, then click **Create**.
+
+.. figure:: /_static/images/cloud-gcp-vpc-01.png
+
+.. figure:: /_static/images/cloud-gcp-vpc-02.png
+   
+   **Private VPC**:
+
+   - Name: ``vyos-private-vpc``
+
+   - Subnet creation mode: ``Custom``
+
+   - Subnet name: ``vyos-private-subnet``
+   
+   - Region: e.g., ``europe-west1``
+
+   - IP range: ``10.0.11.0/24``
+
+   - Leave all other settings at default, then click **Create**.
+
+.. figure:: /_static/images/cloud-gcp-vpc-03.png

+
+
+Step 4: Deploy VyOS instance from Marketplace
+---------
+
+1. Go to the Google Cloud Marketplace page in the Google Cloud console  https://console.cloud.google.com/marketplace
+
+2. Choose the project where you want to deploy the VyOS instance.
+
+.. figure:: /_static/images/cloud-gcp-proj.png
+
+3. In the search bar, type ``vyos`` to find the VyOS image in the Marketplace.
+
+.. figure:: /_static/images/cloud-gcp-market-01.png

+
+7. Configure the network interfaces.
+
+   **Public Network interface:**
+    
+   Edit the first (default) network interface and select following settings:
+
+      - Network: ``vyos-public-vpc``
+
+      - Subnetwork: ``vyos-public-subnet``

+
+      - External IP: ``None``
+
+.. figure:: /_static/images/cloud-gcp-vm-03.png
+
+8. Deployment automation.
+
+   - You can use ``cloud-init`` ``User Data`` to automatically inject specific configuration commands into the VyOS instance during deployment.
+   
+   - Example:
 
   .. code-block:: none
 
-    ssh -i ~/.ssh/vyos_gcp vyos@203.0.113.3
-    vyos@vyos-r1-vm:~$
+   #cloud-config
+   vyos_config_commands:
+      - set system host-name 'VyOS-for-GCP'
+      - set system login banner pre-login 'Welcome to the VyOS for on GCP'
+      - set interfaces ethernet eth0 description 'WAN'
+      - set interfaces ethernet eth1 description 'LAN'
+      - set interfaces ethernet eth1 address 'dhcp'
+      - set interfaces ethernet eth1 dhcp-options no-default-route
+
+For more information, please visit the official VyOS documentation:

+
+
+Connect to the VyOS instance
+-----------
+
+To connect to the VyOS instance, use the SSH key that was generated in the first step.
+
+To retrieve the public IP address, go to the **Google Cloud Console** and navigate to: **Compute Engine** > **VM instances** https://console.cloud.google.com/compute/instances?project=vyos-images
+
+.. figure:: /_static/images/cloud-gcp-vm-08.png
+
+Example:
+
+  .. code-block:: none
+
+   ssh vyos@35.233.97.132 -i .ssh/vyos_gcp
+
+   The authenticity of host '35.233.97.132 (35.233.97.132)' can't be established.
+   ED25519 key fingerprint is SHA256:KCsCnwCGhwX2ba5RcPUAO3ZUSNzS4sXIkujFoScCd0g.
+   This key is not known by any other names
+   Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
+   Warning: Permanently added '35.233.97.132' (ED25519) to the list of known hosts.
