Many articles on some monsters are just a stub (i.e. they've just copied the ingame description), not just monsters other stuff like tools and weapons too. Some other articles too, on the newly added items are not there (such as control-laptop). Crafting recipes for Charcoal Forge, Electric Forge, Hand-Press and die set (swage and die set, and some other things which are forged from scratch), Jackhammer, etc are not there. I don't know how to add recipes, otherwise I would've added them. Many recipes don't have any pointers to indicate how you would learn them (by disassembling, books or just by yourself), I think that needs to be added.
Stubs can be corrected by the addition of more detailed information on that object, tactical information, like how to deal with the said monster (avoiding spoilers when possible). I don't have enough time to add all that stuff and to top it, I haven't even played DDA for months. Correcting stub and empty articles should not be a problem but at this time there's certainly not a guide on the wiki on how to edit a recipe. Guides are in a very good state right now, some had typos (corrected them) but none other than that.
Wiki's is not in a very good state right now but its good to see that its constantly improving, even better than before, well I hope that this just keeps up with the fast development of DDA going on.
