My only suggestion is that you number all pieces and provide instructions in EnglishI was able to use the picture to figure out what pieces went where. The parts need to be marked correctly.I like it to keep my plants alive over the winter, but I really needed to have battery fans and a small portable heater to keep plants alive.I am using my greenhouse for storage and was really excited to get it so quickly. When my handyman put it together, the frame was easy and completed quickly but the cover was not easy because there were no directions and he had to lookup the product an Amazon so that he could figure out how to attach the cover. It is lightweight and assembling the frame was easy until we found that there were no direction for the cover, and I have not had it long enough to rate sturdiness. The company should include directions.Directions are just pictures. This will blow down or collapse if not weighted down. I have to cut slits in the plastic to anchor it down to cinder blocks. The top will collect large puddles of water so I need to add more support to allow the water to run off. After one season of use, the poles are starting to rust. I would not recommend this product.At first thought it was a piece of carp but I kept it used it held it down with cinder blocks and it's ok. It really is small in the big scheme of things best for seedlings and plants that get fried. I tried salads in it. They lasted until early summer but it took lots of care daily watering and just too many hours babying. I used water trays and tarp over top. It made it workable. Without cement blog 's holding it down small breezes can tip it over. So for seeds and some work it's awesome at less than thirty five dollars. All else not so sure.This is easy to put together and comes with instructions. You may have to turn the green plastic cover inside out like I did. The only problem I have with it is that the wind will blow it over if you don't anchor it down somehow. It does not come with anything to do that with so you will have to get creative. Right now we have it against our house and in front of it we put a heavy metal rolling shelf/cart. If you keep this inside against your sliding door/window it will be just fine but we wanted ours outside just in case of spills etc. That being said I just love it! All my plants that I put inside of it are so happy! I started some cuttings so that they could root and this keeps them nice and warm and the humidity is much better in there than outside or inside my home. Plus they don't get drenched when it rains, nor do the birds and squirrels disturb them.
