OEM page reworked

Got baited on the "therefor". Didn't try to improve much, other than removing one "we", when there is already a "we" at the start of a sentence.

Changes Summary

Some shortened words, like "info", and the slightest bit of editing.

@cassidyjames I made these changes just after it was added for translation. It would help to have things sorted out a little bit beforehand, but letting fixes sit duplicates effort in translation.
