# Initial Infrastructure Setup
Once your GCP project has been added to the DuploCloud Portal, the next step is to set up the first Infrastructure.
## Creating an Initial Infrastructure
1. From the DuploCloud Portal, navigate to **Administrator** -> **Infrastructure**, and click **Add**.
2. Give the Infrastructure a **Name**, e.g., nonprod.
3. Select the appropriate **Account**.
4. Enter the **VPC CIDR**, e.g., 10.30.0.0/16 (Note: A /16 CIDR block is recommended for Kubernetes to accommodate its IP address requirements).
5. From the **Cluster Mode** list box, select **GKE Standard**.
6. From the **GKE Endpoint Visibility** list box, select **Public** (for production Infrastructures, set visibility to **Private**).
7. For the remaining fields, keep the default values.

8. Click **Create**. It will take approximately 15 to 20 minutes for the setup to complete. Monitor faults to see if any issues arise (NTP clock sync faults can be ignored).

When the Infrastructure setup is complete, a Plan with the same name as the infrastructure displays on the Plans page (**Administrators** -> **Plans**).
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.duplocloud.com/docs/automation-platform/overview-1/prerequisites/initial-infrastructure-setup.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
