Whether you're trying to give back to the open source community or collaborating on your own projects, knowing how to properly fork and generate pull requests is essential. Unfortunately, it's quite easy to make mistakes or not know what you should do when you're initially learning the process. I know that I certainly had considerable initial trouble with it, and I found a lot of the information on GitHub and around the internet to be rather piecemeal and incomplete - part of the process described here, another there, common hangups in a different place, and so on.

In an attempt to coallate this information for myself and others, this short tutorial is what I've found to be fairly standard procedure for creating a fork, doing your work, issuing a pull request, and merging that pull request back into the original project.

	# Calculate checksum corresponding to the entity-tag hash (ETag) of Amazon S3 objects

	# Usage: compute_etag.sh <filename> <part_size_mb>

	# filename: file to process
	# part_size_mb: chunk size in MiB used for multipart uploads.
	# This is 8M by default for the AWS CLI See:

	export function blurHashToDataURL(hash: string \| undefined): string \| undefined {
	if (!hash) return undefined

	const pixels = decode(hash, 32, 32)
	const dataURL = parsePixels(pixels, 32, 32)
	return dataURL
