+npm-ls(1) -- List installed packages
+======================================
+
+## SYNOPSIS
+
+    npm list [[@<scope>/]<pkg> ...]
+    npm ls [[@<scope>/]<pkg> ...]
+    npm la [[@<scope>/]<pkg> ...]
+    npm ll [[@<scope>/]<pkg> ...]
+
+## DESCRIPTION
+
+This command will print to stdout all the versions of packages that are
+installed, as well as their dependencies, in a tree-structure.
+
+Positional arguments are `name@version-range` identifiers, which will
+limit the results to only the paths to the packages named.  Note that
+nested packages will *also* show the paths to the specified packages.
+For example, running `npm ls promzard` in npm's source tree will show:
+
+    npm@@VERSION@ /path/to/npm
+    └─┬ init-package-json@0.0.4
+      └── promzard@0.1.5
+
+It will print out extraneous, missing, and invalid packages.
+
+If a project specifies git urls for dependencies these are shown
+in parentheses after the name@version to make it easier for users to
+recognize potential forks of a project.
+
+When run as `ll` or `la`, it shows extended information by default.
