Configure Git to use a proxy

##In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

| Title | Description

	# how to run this thingy
	# create a file on your mac called setup.sh
	# run it from terminal with: sh setup.sh

	#!/bin/bash
	set -euo pipefail

	# Display message 'Setting up your Mac...'
	echo "Setting up your Mac..."
	sudo -v

	// Download the "video GIF"
	let data = try! Data(contentsOf: URL(string: "https://thumbs.gfycat.com/ThankfulLawfulAsianelephant-mobile.mp4")!)
	let fileName = String(format: "%@_%@", ProcessInfo.processInfo.globallyUniqueString, "html5gif.mp4")
	let url = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(fileName)
	try! data.write(to: url, options: [.atomic])

	// Do the converties
	let asset = AVURLAsset(url: url)
	guard let reader = try? AVAssetReader(asset: asset) else {
	return

	import UIKit

	class RootViewController: UIViewController {
	override func viewDidAppear(_ animated: Bool) {
	super.viewDidAppear(animated)

	let text = "Cute cat"
	let image = UIImage(named: "cat.jpg")!

	// Note: you can't wrap the text and image into a single "TextImage" object and selectively return both or one as UIActivityItemSource doesn't like holding arrays

	import Foundation

	@propertyWrapper struct Notifier<Value> {
	private let identifier: String

	var wrappedValue: Value? {
	didSet {
	NotificationCenter.default.post(name: Notification.Name(identifier), object: wrappedValue)
	}
	}
