Hi Sja- Sorry for the frustration. The instructions for all variants can be found on the Community Microscope Wiki. If you're using the basic webcam version, you'll want to look at the Microscope Webcam Conversion tutorial. If you've got a kit with the coroplast (white corrugated plastic) stages, the assembly of the stages is printed on the kit itself. If you have stages made from a different material, you might also find this image (also on the wiki page) helpful. Let us know if this helps!
