-The `map` operator can be used to apply a function over a list of inputs.
-
-Here is an example where the `map` operator is used to apply a `resize_image` function over a folder of large images.
-
-```python
-from litdata import map
-from PIL import Image
-
-# Note: Inputs could also refer to files on s3 directly.
-input_dir = "my_large_images"
-inputs = [os.path.join(input_dir, f) for f in os.listdir(input_dir)]
-
-# The resize image takes one of the input (image_path) and the output directory. 
-# Files written to output_dir are persisted.
-def resize_image(image_path, output_dir):
-  output_image_path = os.path.join(output_dir, os.path.basename(image_path))
-  Image.open(image_path).resize((224, 224)).save(output_image_path)
-
-map(
-    fn=resize_image,
-    inputs=inputs, 
-    output_dir="s3://my-bucket/my_resized_images",
-)

-  <summary> ✅ Support S3-Compatible Object Storage</summary>
-&nbsp;
-
-Integrate S3-compatible object storage servers like [MinIO](https://min.io/) with litdata, ideal for on-premises infrastructure setups. Configure the endpoint and credentials using environment variables or configuration files. 
-
-Set up the environment variables to connect to MinIO:
-
-```bash
-export AWS_ACCESS_KEY_ID=access_key
-export AWS_SECRET_ACCESS_KEY=secret_key
-export AWS_ENDPOINT_URL=http://localhost:9000  # MinIO endpoint
-```
-
-Alternatively, configure credentials and endpoint in `~/.aws/{credentials,config}`:
-
-```bash
-mkdir -p ~/.aws && \
-cat <<EOL >> ~/.aws/credentials
-[default]
-aws_access_key_id = access_key
-aws_secret_access_key = secret_key
-EOL
-
-cat <<EOL >> ~/.aws/config
-[default]
-endpoint_url = http://localhost:9000  # MinIO endpoint
-EOL
-```
-Explore an example setup of litdata with MinIO in the [LitData with MinIO](https://github.com/bhimrazy/litdata-with-minio) repository for practical implementation details.
