+npm-help-search(1) -- Search npm help documentation
+===================================================
+
+## SYNOPSIS
+
+    npm help-search some search terms
+
+## DESCRIPTION
+
+This command will search the npm markdown documentation files for the
+terms provided, and then list the results, sorted by relevance.
+
+If only one result is found, then it will show that help topic.
+
+If the argument to `npm help` is not a known help topic, then it will
+call `help-search`.  It is rarely if ever necessary to call this
+command directly.
+
+## CONFIGURATION
+
+### long
+
+* Type: Boolean
+* Default: false
+
+If true, the "long" flag will cause help-search to output context around
+where the terms were found in the documentation.
+
+If false, then help-search will just list out the help topics found.
