[Manwe]

I've started reading The Silmarillion again and was a bit confused when I read the pronunciation in the end. It says that ë in the end of words, like Aulë, Oromë or Manwë, yes I know i should know, but I don't, are pronunced as a "distinct vowel". Does this mean e like in 'end' or the first e in 'here'. Please let me know, I want to know how I should pronunce my name, thanks!
