Need help with OTP Setup

[Excelstra]

So I have been trying to setup a OTP using this guide http://bumped.org/psublog/otp-one-ti...uide-for-pso2/, but it seems to be outdated and I can't even create an account in the app.
Almost all text is in Japanese and I can't copy/paste the text to make any sense of it.
If someone could give me a quick guide on how to create an account in the app and get me to a point where the above guide leads me through the rest, it would be really appreciated.

Edit: Managed to get it to work. It somehow defaulted to Japanese, since my devices were set to Swedish as the default language. I changed it to English(UK) and suddenly I can understand something. Maybe this helps someone with the same problem.
