+
+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
+
+<Note type="check">
+
+- [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",
+      options: { 
+        redisUrl: process.env.CACHE_REDIS_URL,
+      },
+    },
+  },
+}
+```
