If you cannot read Japanese, then it is recommended to view these links with Google Chrome. You may also use Google Translate's webpage translation service, but Google Chrome is faster and has the ability to turn on and off translations. It's important to note that when viewing the translated CatSystem2 manual, whitespace will not always be correct. You should turn off and on translations to compare how the whitespace should actually be when reading the documentation.
