 ## Crud Controller
 
-Our newly generated working horse. Let's dive in some details.
+Our newly generated working horse. `@Crud()` decorator accepts two arguments - Entity class and `CrudOptions` object. Let's dive in some details.
+
+### Restful Options merge
+
+```typescript
+...
+import { Crud } from '@nestjsx/crud';
+
+@Crud(Hero, {
+  options: {
+    // RestfulOptions goes here
+  }
+})
+@Controller('heroes')
+export class HeroesCrudController {
+  constructor(public service: HeroesService) {}
+}
+```
+
+`CrudOptions` object may have `options` parameter which is the same object as [Restful Options](#restful-options).
+
+**_Notice:_** If you have this options set up in your `RepositoryService`, in that case they will be **merged**.
+
+### Path Filter
+
+`CrudOptions` object may have `params` parameter that will be used for auto filtering by URL path parameters.
+
+Assume, you have an entity `User` that belongs to some `Company` and has a field `companyId`. And you whant to create `UsersController` so that an admin could access users from his own Company only. Let's do this:
+
+```typescript
+...
+import { Crud } from '@nestjsx/crud';
+
+@Crud(Hero, {
+  params: ['companyId']
+})
+@Controller('/company/:companyId/users')
+export class UsersCrud {
+  constructor(public service: UsersService) {}
+}
+```
+
+In this example you're URL param name `companyId` should match the name of `User.companyId` field. If not, you can do mapping, like this:
+
+```typescript
+...
+import { Crud } from '@nestjsx/crud';
+
+@Crud(Hero, {
+  params: {
+    company: 'companyId'
+  }
+})
+@Controller('/company/:company/users')
+export class UsersCrud {
+  constructor(public service: UsersService) {}
+}
+```
+
+Where `company` is the name of the URL param, and `companyId` is the name of the entity field.
+
+As you might guess, all request will add `companyId` to the DB queries alongside with the `:id` of `GET`, `PATCH`, `DELETE` requests. On `POST` (both: one and bulk) requests, `companyId` will be added to the `dto` automatically.
+
+When you done with the controller, you'll need to add some logic to your `AuthGuard` or any other interface, where you do the authorization of a requester. You will need to match `companyId` URL param with the `user.companyId` entity that has been validated from the DB.
