 The general notation for rotational ciphers is `ROT + <key>`.
 The most commonly used rotational cipher is `ROT13`.
 
 A `ROT13` on the Latin alphabet would be as follows:
 
-```plain
+```text
 Plain:  abcdefghijklmnopqrstuvwxyz
 Cipher: nopqrstuvwxyzabcdefghijklm
 ```
 
 It is stronger than the Atbash cipher because it has 27 possible keys, and 25 usable keys.
 
 Ciphertext is written out in the same formatting as the input including spaces and punctuation.
 
 ## Examples

 - ROT5  `omg` gives `trl`
 - ROT0  `c` gives `c`
 - ROT26 `Cool` gives `Cool`
 - ROT13 `The quick brown fox jumps over the lazy dog.` gives `Gur dhvpx oebja sbk whzcf bire gur ynml qbt.`
 - ROT13 `Gur dhvpx oebja sbk whzcf bire gur ynml qbt.` gives `The quick brown fox jumps over the lazy dog.`
