Ibook Store ipa

Dear Apple Support

I've created an APP on a webpage called Aquro.

I've now downloaded the .ipa file and uploaded it in AppleStore.

I got the reply, that my APP has a lot of text in it, so it should be uploaded in Ibook Store.

Now my question is; How do I upload in .ipa file in Ibook Store - is that even possible?

Thanks,
