+# Instructions
+
+Your task is to translate text from English to Pig Latin.
+The translation is defined using four rules, which look at the pattern of vowels and consonants at the beginning of a word.
+These rules look at each word's use of vowels and consonants:
+
+- vowels: the letters `a`, `e`, `i`, `o`, and `u`
+- consonants: the other 21 letters of the English alphabet
+
+## Rule 1
+
+If a word begins with a vowel, or starts with `"xr"` or `"yt"`, add an `"ay"` sound to the end of the word.
+
+For example:
+
+- `"apple"` -> `"appleay"` (starts with vowel)
+- `"xray"` -> `"xrayay"` (starts with `"xr"`)
+- `"yttria"` -> `"yttriaay"` (starts with `"yt"`)
+
+## Rule 2
+
+If a word begins with one or more consonants, first move those consonants to the end of the word and then add an `"ay"` sound to the end of the word.
+
+For example:
+
+- `"pig"` -> `"igp"` -> `"igpay"` (starts with single consonant)
+- `"chair"` -> `"airch"` -> `"airchay"` (starts with multiple consonants)
+- `"thrush"` -> `"ushthr"` -> `"ushthray"` (starts with multiple consonants)
+
+## Rule 3
+
+If a word starts with zero or more consonants followed by `"qu"`, first move those consonants (if any) and the `"qu"` part to the end of the word, and then add an `"ay"` sound to the end of the word.
+
+For example:
+
+- `"quick"` -> `"ickqu"` -> `"ickquay"` (starts with `"qu"`, no preceding consonants)
+- `"square"` -> `"aresqu"` -> `"aresquay"` (starts with one consonant followed by `"qu`")
+
+## Rule 4
+
+If a word starts with one or more consonants followed by `"y"`, first move the consonants preceding the `"y"`to the end of the word, and then add an `"ay"` sound to the end of the word.
+
+Some examples:
+
+- `"my"` -> `"ym"` -> `"ymay"` (starts with single consonant followed by `"y"`)
+- `"rhythm"` -> `"ythmrh"` -> `"ythmrhay"` (starts with multiple consonants followed by `"y"`)

+# Introduction
+
+Your parents have challenged you and your sibling to a game of two-on-two basketball.
+Confident they'll win, they let you score the first couple of points, but then start taking over the game.
+Needing a little boost, you start speaking in [Pig Latin][pig-latin], which is a made-up children's language that's difficult for non-children to understand.
+This will give you the edge to prevail over your parents!
