# How to Use Cache Module
|
||
|
||
In this document, you’ll learn about the different methods in the Cache Module's service and how to use them.
|
||

|
||
## Resolve Cache Module's Service
|
||
|
||
In your workflow's step, you can resolve the Cache Module's service from the Medusa container:
|
||
|
||
```ts
|
||
import { Modules } from "@medusajs/framework/utils"
|
||
import { createStep } from "@medusajs/framework/workflows-sdk"
|
||
|
||
const step1 = createStep(
|
||
"step-1",
|
||
async ({}, { container }) => {
|
||
const cacheModuleService = container.resolve(
|
||
Modules.CACHE
|
||
)
|
||
|
||
// TODO use cacheModuleService
|
||
}
|
||
)
|
||
```
|
||
|
||
This will resolve the service of the configured Cache Module, which is the [In-Memory Cache Module](https://docs.medusajs.com/resources/architectural-modules/cache/in-memory) by default.
|
||
|
||
You can then use the Cache Module's service's methods in the step. The rest of this guide details these methods.
