How to update to Ckeditor 4

[Pokecity]

I managed to update Ckeditor 3.5.2 to Ckeditor 4.1.

Steps:
1. Go to here: https://ckeditor.com/ckeditor-4/download/ and dowload the zip.
2. Unzip Ckeditor.
3. Upload contents to inc folder.
4. Make a copy of ckeditor.php from the current ckeditor folder, and put the copy in the new ckeditor folder.
5. Name the current ckeditor folder to ckeditorOld, then name the new ckeditor folder to ckeditor.
6. Change config.js to the language and background color you want it to be, and you're done!
