+This hook allows you to use ZFS as your root filesystem.
+
+Command Line Setup:
+
+    You can append the following arguments to your kernel parameters list. See
+    https://wiki.archlinux.org/index.php/Kernel_parameters for more information.
+
+    To use ZFS as your boot filesystem:
+
+        zfs=bootfs or zfs=auto or root=zfs
+
+    To use a pool or dataset:
+
+        zfs=<pool/dataset>
+
+    To force importing of a ZFS pool:
+
+        zfs_force=1
+
+        If set to 1, this will use "zpool import -f" when attempting to import
+        pools.
+
+    To change the seconds of time to wait for ZFS devices to show up at boot:
+
+        zfs_wait=30
+
+    To search for devices in a directory other than "/dev":
+
+        zfs_import_dir=/dev/disk/by-uuid
+            or
+        zfs_import_dir=/dev/disk/by-partuuid
+            or
+        zfs_import_dir=/dev/disk/by-path
+            etc.
+
+    Following initcpio convention, the 'rw' option must be specified to load the
+    pool as read/write. Pools are loaded as read only by default.
+
+Examples:
+
+    To use bootfs on your pool, use
+
+        zfs=bootfs rw
+
+    This will setup your root using tank/root zfs pool.
+
+        zfs=tank/root rw
+
+If you want to set properties for zfs-on-linux module, you should add them to
+/etc/modprobe.d/zfs.conf and then rebuild initcpio.
