+          $ npm-check <path> <options>
+
+        Path
+          Where to check. Defaults to current directory. Use -g for checking global modules.
+
+        Options
+          -u, --update          Interactive update.
+          -y, --update-all      Uninteractive update. Apply all updates without prompting.
+          -g, --global          Look at global modules.
+          -s, --skip-unused     Skip check for unused packages.
+          -p, --production      Skip devDependencies.
+          -d, --dev-only        Look at devDependencies only (skip dependencies).
+          -i, --ignore          Ignore dependencies based on succeeding glob.
+          -E, --save-exact      Save exact version (x.y.z) instead of caret (^x.y.z) in package.json.
+          --specials            List of depcheck specials to include in check for unused dependencies.
+          --no-color            Force or disable color output.
+          --no-emoji            Remove emoji support. No emoji in default in CI environments.
+          --debug               Debug output. Throw in a gist when creating issues on github.
+
+        Examples
+          $ npm-check           # See what can be updated, what isn't being used.
+          $ npm-check ../foo    # Check another path.
+          $ npm-check -gu       # Update globally installed modules by picking which ones to upgrade.
