i think your proposal with a index is a possibility, but i must say that in my experience seperate pages work much better if you want to convey a message.
...i was even thinking about splitting it up some more,
it also gives the possibility to put the other methodes in a similar frame.
but if you want 1 page, i suggest only page 1-5, drop everything else except for the links to other methods, that is too much of a read already.
and I'm not in a rush, for me it is clear without the instruction
it is now out of my hands, if nobody responds I can only assume I did a good job
