 We highly recommend using `hugo.Generator` in your website's `<head>`. `hugo.Generator` is included by default in all themes hosted on [themes.gohugo.io](https://themes.gohugo.io). The generator tag allows the Hugo team to track the usage and popularity of Hugo.

+`hugo.Deps` returns a list of dependencies for a project (either Hugo Modules or local theme components).
+
+Eeach dependency contains:
+
+Path (string)
+: Returns the path to this module. This will either be the module path, e.g. "github.com/gohugoio/myshortcodes", or the path below your /theme folder, e.g. "mytheme".
+
+Version (string)
+:  The module version.
+	
+Vendor (bool)
+: Whether this dependency is vendored.
+ 
+Time (time.Time)
+: Time version was created.
+
+Owner
+: In the dependency tree, this is the first module that defines this module as a dependency.
+
+Replace (*Dependency)
+: Replaced by this dependency.
+
+An example table listing the dependencies:
