+tmpfs workspace
+---------------
+
+The ``tmpfs workspace`` plugin mounts a tmpfs filesystem for the
+workspace temporary files. This is useful when the workspace directory
+is placed on a slow medium (e.g. a hard disk drive), the build process
+performs lots of local I/O (e.g. building a vagrant box), and there is
+enough RAM to store data necessary for the build process. For example,
+the ``stretch-vagrant.yml`` manifest file from the examples directory
+takes 33 minutes to build on the plugin author's home server. Using
+this plugin reduces this time to 3 minutes at the cost of 1.2GB of
+additional RAM usage.
+
+Settings
+~~~~~~~~
+
+This plugin has no settings. To enable it add ``"tmpfs_workspace":{}``
+to the plugin section of the manifest.
