Also, some sources: Mline's notes from his web page are pretty useful and informative. Then there's
Neukirch's book "Algebraic Number Theory"

Someone wrote a section in TeX, not realizing that TeX doesn't quite work like that, here.

I hope someone knowledgeable about fractional ideals can rewrite that sentence in
English.
