# Why Modules?
Declaring derivations as modules solves a number of issues.
For more details on the problems, visit [DavHau/pkgs-modules](https://github.com/DavHau/pkgs-modules).
Also I recommend watching @edolstra 's [talk about this topic](https://www.youtube.com/watch?v=dTd499Y31ig).
For some more background information, check out the initial exploration of this idea at [DavHau/pkgs-modules](https://github.com/DavHau/pkgs-modules).
@edolstra 's [talk about this topic](https://www.youtube.com/watch?v=dTd499Y31ig) is also worth watching.
