 **Now**, we can use redis in two ways.
 
-via decorator:
-
 ```ts
 import { Injectable } from '@nestjs/common';
-import { InjectRedis, DEFAULT_REDIS_NAMESPACE } from '@liaoliaots/nestjs-redis';

 And there we go.
-
-### Testing
-
-This package exposes `getRedisToken()` function that returns an internal injection token based on the provided context. Using this token, you can provide a mock implementation of the redis instance using any of the standard custom provider techniques, including `useClass`, `useValue`, and `useFactory`.
-
-```ts
-import { Test, TestingModule } from '@nestjs/testing';
-import { getRedisToken } from '@liaoliaots/nestjs-redis';
-
-const module: TestingModule = await Test.createTestingModule({
-  providers: [{ provide: getRedisToken('namespace'), useValue: mockedInstance }, YourService]
-}).compile();
-```
-
-A working example is available [here](/sample).
