# Creating and Modifying a Custom Provider Configuration

To add a Custom Provider:

1. In the RAS Console, navigate to **Farm** > **Site** > **Providers**.
2. On the **Providers** tab, click **Tasks** > **Add** > **Custom Provider**
3. Provide a **Name** and **Description** for the Custom Provider. In this example, we use Proxmox as the example platform.
4. Optionally, provide **credentials** for communication with the **Connection Broker**, and provide credentials for deploying the **Guest Agent**. This is similar to how other providers are created.
5. Note that **Check credentials** does not work until the Provider connection details and variables are first configured. You can optionally go back to this section to perform the check credentials.
6. Click **Next**.
7. Provide the **command**, **command** **arguments**, and **working** **directory** of your custom provider code
   1. Example values:\
      `C:\Program Files\PowerShell\7\pwsh.exe`\
      `-NoProfile -NonInteractive -ExecutionPolicy Bypass -File` `C:\CPF_Scripts\Parallels-RAS-CPF-Basic.ps1`

      `C:\CPF_Scripts`
8. Click **Next**.
9. Customize the variables and **values** to be passed to the custom provider code. The information provided here depends on how the custom provider code is implemented.
10. Additional variables can be added as required. For example, if you introduce various logging levels in the custom code, you can customize the log level here to pass to the script.
11. Use the plus sign to add new variables, which can be either regular or secure.
12. Click **Next**.
13. Verify the details and confirm that the status is verified and valid
14. Click **Next**.
15. Confirm the details provided in the summary
16. Click **Finish** and **Apply** the configuration.
17. Confirm that the provider’s status is OK.

### Modifying the Provider Configuration

To view and modify the Provider configuration, right-click it and choose **Properties**. In the dialog that opens, view and modify the Provider properties.

## 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.parallels.com/landing/ras-admin-guide/parallels-ras-21-administrators-guide/virtual-desktop-infrastructure-vdi/add-a-provider/add-a-custom-provider/creating-and-modifying-a-custom-provider-configuration.md?ask=<question>&goal=<endgoal>
```

`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.
