My advice is that you print the build manual.
You might only read it on screen but I personally prefer to have it printed.

Also BfB's building instructions in PDF 3D format are very well done !
Don't hesitate to check it twice before doing a mistake.
Some part's correct side can be hardly identified without it...

So after about 5 hours of work I reached the page 31 and decided to stop for today.
All the corners and other parts are now ready for assembling.
I will do that tomorow...
