+Indicates that you don't want npm to make any changes and that it should

+commands that modify your local installation, eg, `install`, `update`,
+`dedupe`, `uninstall`, as well as `pack` and `publish`.

 If you don't have a clear idea of what you want to do, it is strongly
 recommended that you do not use this option!
 
+#### `workspace`
+
+* Default:
+* Type: String (can be set multiple times)
+
+Enable running a command in the context of the configured workspaces of the
+current project while filtering by running only the workspaces defined by
+this configuration option.
+
+Valid values for the `workspace` config are either:
+
+* Workspace names
+* Path to a workspace directory
+* Path to a parent workspace directory (will result to selecting all of the
+  nested workspaces)
+
+When set for the `npm init` command, this may be set to the folder of a
+workspace which does not yet exist, to create the folder and set it up as a
+brand new workspace within the project.
+
+This value is not exported to the environment for child processes.
+
+#### `workspaces`
+
+* Default: false
+* Type: Boolean
+
+Enable running a command in the context of **all** the configured
+workspaces.
+
+This value is not exported to the environment for child processes.
