Mintlify.Core.Models.Error404Config
```

## Summary

Represents the configuration for 404 (Not Found) error handling in the Mintlify documentation site.

## Remarks

This configuration controls what happens when users try to access pages that don't exist,
including whether to automatically redirect them to the home page.

## Constructors

### <Icon icon="hammer" iconType="duotone" color="#419AC5" size={24} className="mr-2" /> .ctor

#### Syntax

```csharp theme={"dark"}
public Error404Config()
```

### <Icon icon="hammer" iconType="duotone" color="#419AC5" size={24} className="mr-2" /> .ctor <Badge color="gray">Inherited</Badge>

<Note>Inherited from `object`</Note>

#### Syntax

```csharp theme={"dark"}
public Object()
```

## Properties

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} className="mr-2" /> Description

Gets or sets a custom description for the 404 error page.

#### Syntax

```csharp theme={"dark"}
public string Description { get; set; }
```

#### Property Value

Type: `string?`

#### Remarks

When specified, this description appears below the title on the 404 page.

### <Icon icon="tag" iconType="duotone" color="#419AC5" size={24} className="mr-2" /> Redirect

Gets or sets whether to automatically redirect users to the home page when a 404 error occurs.

#### Syntax

```csharp theme={"dark"}
public System.Nullable<bool> Redirect { get; set; }
```

#### Property Value

Type: `System.Nullable<bool>?`

#### Remarks

When true (default), users who navigate to non-existent pages will be automatically
redirected to the home page of the documentation site. When false, users will see
a standard 404 error page instead. Automatic redirection can improve user experience
by keeping users within the documentation rather than showing error pages.
