+## Setup Redis with Amazon ElastiCache
+
+AWS Amplify does not include Redis by default. To use Redis for caching, you need to set up [Amazon ElastiCache](https://aws.amazon.com/elasticache/) or use an external Redis provider.
+
+### Option 1: Amazon ElastiCache
+
+Amazon ElastiCache is a fully managed in-memory data store service compatible with Redis.
+
+1. Navigate to the [ElastiCache Console](https://console.aws.amazon.com/elasticache/).
+2. Click "Create" and select "Redis OSS" as the cluster engine.
+3. Configure your cluster settings (node type, number of replicas, etc.).
+4. Configure security groups to allow access from your Amplify application.
+5. Once created, note the **Primary Endpoint** for your Redis connection.
+
+::: warning
+ElastiCache runs within a VPC. Connecting from AWS Amplify (which runs outside VPC by default) requires additional configuration such as VPC peering or using a public endpoint. For serverless applications, consider using Option 2.
+:::
+
+### Option 2: Serverless Redis providers
+
+For easier integration with serverless deployments like AWS Amplify, consider using:
+
+- [Upstash](https://upstash.com/) - Serverless Redis with REST API support, ideal for edge/serverless environments.
+- [Redis Cloud](https://redis.com/cloud/overview/) - Managed Redis with public endpoints.
+
+These providers offer public endpoints that work seamlessly with AWS Amplify without VPC configuration.
+
+### Configure Redis environment variables
+
+After setting up Redis (ElastiCache or a serverless provider), configure these environment variables in AWS Amplify:
+
+```bash
+REDIS_CACHE=true
+REDIS_HOST=your-redis-endpoint.cache.amazonaws.com  # Or your provider's endpoint
+REDIS_PORT=6379
+REDIS_PASSWORD=your_redis_password
+REDIS_TLS=true  # Recommended for production
+```
+
+Add these variables in the AWS Amplify Console under "Environment variables" in your app settings, or include them in your `.env.template` file.
+
 ## Deploy
 
 - Login to the AWS Amplify Hosting Console.

+## Setup Redis with Upstash
+
+Cloudflare Pages/Workers do not include a built-in Redis service. [Upstash](https://upstash.com/) is the recommended serverless Redis provider that integrates natively with Cloudflare.
+
+### Create an Upstash Redis database
+
+1. Sign up at [Upstash Console](https://console.upstash.com/).
+2. Click "Create Database" and select a region close to your users.
+3. Once created, navigate to the database details page.
+4. Copy the connection details:
+   - **REDIS_HOST**: The endpoint URL (e.g., `xxx.upstash.io`)
+   - **REDIS_PORT**: Usually `6379` or the TLS port `6380`
+   - **REDIS_PASSWORD**: The password from the database details
+   - **REDIS_TLS**: Set to `true` for secure connections
+
+### Configure environment variables
+
+Add these Redis environment variables to your `.env` file:
+
+```bash
+REDIS_CACHE=true
+REDIS_HOST=your-database.upstash.io
+REDIS_PORT=6379
+REDIS_PASSWORD=your_upstash_password
+REDIS_TLS=true
+```
+
+### Cloudflare integration (optional)
+
+You can also set up the Upstash integration directly in Cloudflare:
+
+1. Go to [Cloudflare Dashboard](https://dash.cloudflare.com/) → Workers & Pages → Your project.
+2. Navigate to Settings → Integrations.
+3. Find and add the Upstash integration.
+4. Follow the prompts to connect your Upstash account.

 ## Deploy from a local machine
 
 - Due to this [issue](https://github.com/nuxt/nuxt/issues/28248), just make sure your `.npmrc` file has the following content:

+## Setup Redis
+
+Redis is required for caching. You can either install Redis locally on your Ubuntu server or use a managed Redis service.
+
+### Option 1: Install Redis locally
+
+Install Redis using the package manager:
+
+```bash
+sudo apt update
+sudo apt install redis-server
+```
+
+Configure Redis for production by editing the configuration file:
+
+```bash
+sudo nano /etc/redis/redis.conf
+```
+
+Key settings to consider:
+
+- Set `supervised systemd` to integrate with systemd.
+- Configure `bind` to restrict access (e.g., `bind 127.0.0.1` for local only).
+- Set a password with `requirepass your_secure_password`.
+
+Enable and start the Redis service:
+
+```bash
+sudo systemctl enable redis-server
+sudo systemctl start redis-server
+```
+
+Verify Redis is running:
+
+```bash
+# If you configured a password with requirepass
+redis-cli -a your_secure_password ping
+
+# If no password is set
+redis-cli ping
+```
+
+You should see `PONG` as a response.
+
+### Option 2: Use a managed Redis service
+
+Alternatively, you can use managed Redis services such as:
+
+- [Upstash](https://upstash.com/) - Serverless Redis with pay-per-request pricing.
+- [Redis Cloud](https://redis.com/cloud/overview/) - Managed Redis by Redis Ltd.
+
+These services provide connection details (host, port, password) that you configure in your `.env` file.
+
+### Configure Redis environment variables
+
+Add these Redis environment variables to your `.env` file:
+
+```bash
+REDIS_CACHE=true
+REDIS_HOST=127.0.0.1  # For local installation, or your managed service endpoint
+REDIS_PORT=6379
+REDIS_PASSWORD=your_secure_password  # If configured with requirepass
+REDIS_TLS=false  # Set to true for managed services that require TLS
+```
+
+For managed Redis services like Upstash, use the connection details provided by the service (host, port, password, and set `REDIS_TLS=true` for secure connections).
