You can reach the documentation pages of my products with Qbox framework on the sub-pages of this page.
If you're using the Qbox framework, make sure to enable ox_lib support for all Wert scripts through their configuration files.
Also, if you're using ox_inventory, be sure to activate that as well.
If you're using a different inventory system, you can configure it manually through the editable_server.lua file found inside each script.
