# Instructions
2+
3+
Your task is to figure out if a sentence is a pangram.
4+
5+
A pangram is a sentence using every letter of the alphabet at least once.
6+
It is case insensitive, so it doesn't matter if a letter is lower-case (e.g. `k`) or upper-case (e.g. `K`).
7+
8+
For this exercise, a sentence is a pangram if it contains each of the 26 letters in the English alphabet.

# Introduction
2+
3+
You work for a company that sells fonts through their website.
4+
They'd like to show a different sentence each time someone views a font on their website.
5+
To give a comprehensive sense of the font, the random sentences should use **all** the letters in the English alphabet.
6+
7+
They're running a competition to get suggestions for sentences that they can use.
8+
You're in charge of checking the submissions to see if they are valid.

~~~~exercism/note
11+
Pangram comes from Greek, παν γράμμα, pan gramma, which means "every letter".
12+
13+
The best known English pangram is:
14+
15+
> The quick brown fox jumps over the lazy dog.
