# Alert

Add alert components to PowerShell Universal apps with New-UDAlert, using severity levels, titles, and custom content to communicate messages to users.

Alerts provide a simple way to communicate information to a user.

## Simple Alerts

Alerts have four different severities and can include text or other content.

```
New-UDAlert -Severity 'error' -Text 'This is an error alert — check it out!' 
New-UDAlert -Severity 'warning' -Text 'This is an warning alert — check it out!'
New-UDAlert -Severity 'info' -Text 'This is an error info — check it out!' 
New-UDAlert -Severity 'success' -Text 'This is an success alert — check it out!'
```

## Advanced Alerts

Alerts can contain any component and also a title.

```
New-UDAlert -Severity 'error' -Content { New-UDHtml 'This is an error alert — <strong>check it out!</strong>' } -Title "Error"
New-UDAlert -Severity 'warning' -Content { New-UDHtml 'This is an warning alert — <strong>check it out!</strong>' } -Title "Warning"
New-UDAlert -Severity 'info' -Content { New-UDHtml 'This is an error info — <strong>check it out!</strong>' } -Title "Info"
New-UDAlert -Severity 'success' -Content { New-UDHtml 'This is an success alert — <strong>check it out!</strong>' } -Title "Success"
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/powershell-universal/apps/components/data-display/alert.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
