What is to do?
Is there a howto?
No - but a first clue,
from us to you.

When you arrive
cheerful and alive
ready to dive
into a somehow different T5

Near "A" at the forest
begins your quest.
No time to rest
peek for a hint - unstressed.

And you hopefully know
where to go
to find a depot
with "B" and a tableau.

All further explanations
to the remaining stations
extract from the relations
of a sketch and its equations.

So go and look for these,
very special trees?
First, a warning - please,
nothing for rookies!
