+You can easily update your installed packages by running:
+```
+pkgit update

+## Declaring Packages
+If you prefer a declarative approach, you can use the config file (read below) as a package declaration file.

+```
+pkgit declare

+pkgit d

 ## Dependency Management
 As it is, pkgit is capable of dependency management, but you will likely have to specify the dependency URLs for each package you install in `<config_directory>/pkgit/init.lua`. There's not a universal way to check for dependencies without using an existing package manager (unless the package you're installing has a bldit.lua).
