### 1. Add required services

Inject the `SieveProcessor` service. So in `Startup.cs` add:

Sieve will only sort/filter properties that have the attribute `[Sieve(CanSort = true, CanFilter = true)]` on them (they don't have to be both true).
|

So for our `Post` entity model example:
|
||||
```
|
||||
```C#
|
||||
public int Id { get; set; }

In the action that handles returning Posts, use `SieveModel` to get the sort/filter/page query.

Apply it to your data by injecting `SieveProcessor` into the controller and using its `Apply<TEntity>` method. So for instance:
|
||||
```

## Configure Sieve
|
||||
Use the [ASP.NET Core options pattern](https://docs.microsoft.com/en-us/aspnet/core/fundamentals/configuration/options) with `SieveOptions` to tell Sieve where to look for configuration. For example:
|
||||
```
|
||||
```C#
|
||||
services.Configure<SieveOptions>(Configuration.GetSection("Sieve"));
|
||||
```
|
||||
Then you can add the configuration:
|
||||
```
|
||||
```json
|
||||
{
|
||||
"Sieve": {
|
||||
"CaseSensitive": `boolean: should property names be case-sensitive? Defaults to false`,
