+					Create a BTRFS volume or subvolume. For a volume, the syntax is:
+					</para>
+					
+<screen>btrfs <replaceable>&lt;mntpoint&gt;</replaceable> --data=<replaceable>&lt;level&gt;</replaceable> --metadata=<replaceable>&lt;level&gt;</replaceable> --label=<replaceable>&lt;label&gt;</replaceable> <replaceable>&lt;partitions&gt;</replaceable></screen>
+
+ <para>
+   <replaceable>&lt;partitions&gt;</replaceable> denotes that multiple partitions can be listed and should list the BTRFS identifiers to add to the BTRFS volume.
+ </para>
+ 
+ <para>
+   For a subvolume, the syntax is:
+ </para>
+ 
+<screen>btrfs <replaceable>&lt;mntpoint&gt;</replaceable> --subvol --name=<replaceable>&lt;path&gt;</replaceable> <replaceable>&lt;parent&gt;</replaceable></screen>
+
+ <para>
+   <replaceable>&lt;parent&gt;</replaceable> should be the identifier of the subvolume's parent volume.
+ </para>
+ 
+ <para>
+    None of the following options apply to subvolumes.
