this mod adds a way to trade much like the black market mod without all the UPS problems and initial game delay. Also vaderciya, I understand where you are coming from but the mod itself is the description and I'm sure myself and most of the ~million 5Dim downloaders would happily vouch for 5Dim.
Edit: checking the source listed by authors is another good way to find descriptions. Here is a link to 5Dim's readme with a brief description of all the wonderful mods. https://github.com/McGuten/5DimsFactorioMods/blob/master/README.md
