 # S3 Bucket Configuration
+
+This guide covers two options for S3 storage configuration:
+- **[Option 1: MinIO (Local Development)](#minio-local-development)** - Recommended for local development
+- **[Option 2: AWS S3 (Production)](#aws-s3-production)** - For production environments
+
+## MinIO (Local Development)
+
+MinIO is an S3-compatible object storage server that can run locally, making it ideal for development without needing AWS credentials or incurring cloud storage costs.
+
+### Installation
+
+Install `minio-client` from a package manager then, choose one of the following installation methods:
+
+#### Option A: AUR (Arch Linux)
+```bash
+yay -S minio
+```
+
+#### Option B: Download Binary (Linux)
+```bash
+wget https://dl.min.io/server/minio/release/linux-amd64/minio
+chmod +x minio
+sudo mv minio /usr/local/bin/
+```
+
+Visit [https://www.min.io/download](https://www.min.io/download) for other installation options.
+
+### Setup
+
+1. **Start MinIO server:**
+```bash
+minio server minio/ --console-address ":9090"
+```
+
+This will start MinIO and create the folder if it doesn't exist and outputs the following information:
+- API endpoint (typically `http://127.0.0.1:9000`)
+- WebUI (typically `http://127.0.0.1:9090`)
+- Root credentials (default: `minioadmin` / `minioadmin`)
+
+2. **Access the MinIO Web Console:**
+   - Open your browser and navigate to `http://127.0.0.1:9090`
+   - Login (default):
+     - Username: `minioadmin`
+     - Password: `minioadmin`
+
+3. **Create a bucket:**
+   - In the left panel, click "Create Bucket"
+   - Enter bucket name: `p5js-editor`
+   - Click "Create Bucket"
+
+4. **Configure bucket access (Public Access):**
+   - In your prefered terminal, configure the bucket to allow anonymous viewing `mcli anonymous set public local/p5js-editor`
+
+5. **Update your `.env` file:**
+```bash
+# MinIO Configuration
+AWS_ACCESS_KEY=minioadmin
+AWS_SECRET_KEY=minioadmin
+AWS_REGION=us-east-1
+AWS_S3_ENDPOINT=http://127.0.0.1:9000
+AWS_S3_SIGNATURE_VERSION=v4
+S3_BUCKET=p5js-editor
+S3_BUCKET_URL_BASE=http://127.0.0.1:9000/p5js-editor/
+```
+
+6. **Update S3 client configuration in code:**
+
+The following files need to be updated to use MinIO locally:
+
+**server/controllers/aws.controller.js:**
+```javascript
+const s3Client = new S3Client({
+  endpoint: process.env.AWS_S3_ENDPOINT || 'http://127.0.0.1:9000',
+  credentials: {
+    accessKeyId: process.env.AWS_ACCESS_KEY,
+    secretAccessKey: process.env.AWS_SECRET_KEY
+  },
+  region: process.env.AWS_REGION,
+  forcePathStyle: true
+});
+```
+
+**server/migrations/s3UnderUser.js:**
+```javascript
+const s3Client = new S3Client({
+  endpoint: process.env.AWS_S3_ENDPOINT || 'http://127.0.0.1:9000',
+  credentials: {
+    accessKeyId: process.env.AWS_ACCESS_KEY,
+    secretAccessKey: process.env.AWS_SECRET_KEY
+  },
+  region: process.env.AWS_REGION,
+  forcePathStyle: true
+});
+```
+
+## AWS S3 (Production)
+
+For production environments, use AWS S3:
+
 1. [Create an S3 bucket](https://docs.aws.amazon.com/AmazonS3/latest/userguide/create-bucket-overview.html), with any name.
 2. Navigate to the S3 bucket permissions and add the following CORS policy. This is for development only, as it allows CORS from any origin.
 ```
