+
+The In-Memory Cache Module uses a plain JavaScript Map object to store the cached data. This module is used by default in your Medusa application.
+
+This module is helpful for development or when you’re testing out Medusa, but it’s not recommended to be used in production.
+
+For production, it’s recommended to use modules like [Redis Cache Module](../redis/page.mdx).
+
+---
+
+## Install the In-Memory Cache Module
+
+To install the In-Memory Cache Module, run the following command in the directory of your Medusa application:
+
+```bash npm2yarn
+npm install @medusajs/cache-inmemory
+```
+
+Next, add the module into the `modules` property of the exported object in `medusa-config.js`:
+
+```js title="medusa-config.js"
+module.exports = {
+  // ...
+  modules: {
+    // ...
+    cacheService: {
+      resolve: "@medusajs/cache-inmemory",
+      options: {
+        // optional options
+      },
+    },
+  },
+}
+```

+
+The Redis Cache Module uses Redis to cache data in your store. In production, it's recommended to use this module.

+
+## Install the Redis Cache Module

+- [Redis installed and Redis server running](https://redis.io/docs/getting-started/installation/).
+
+</Note>
+
+To install Redis Cache Module, run the following command in the directory of your Medusa application:
+
+```bash npm2yarn
+npm install @medusajs/cache-redis
+```
+
+Next, add the module into the `modules` property of the exported object in `medusa-config.js`:
+
+export const highlights = [
+  ["8", "redisUrl", "The Redis connection URL."]
+]
+
+```js title="medusa-config.js" highlights={highlights}
+module.exports = {
+  // ...
+  modules: {
+    // ...
+    cacheService: {
+      resolve: "@medusajs/cache-redis",
