Storing Images and Demos in your Repo

In this quick walkthough you'll learn how to create a separate branch in your repo to house your screenshots and demo gifs for use in your master's readme.

How to

1. Clone a fresh copy of your repo

In order to prevent any loss of work it is best to clone the repo in a separate location to complete this task.

2. Create a new branch

Create a new branch in your repo by using git checkout --orphan assets

extension String{
    private func min(numbers: Int...) -> Int {
        return numbers.reduce(numbers[0], {$0 < $1 ? $0 : $1})
    }
    
    func distanceFrom(string: String) -> Int{
        let x = Array(self.utf16) //convert to a unicode 16 format for comparison
        let y = Array(string.utf16)
        
        //Create the Levenshtein 2d matrix, which has an extra preceeding row and column
