+\fBsubvolume delete\fR [-R] \fI <subvolume> \fP[\fI<subvolume>...\fP]\fR
 Delete the subvolume \fI<subvolume>\fR. If \fI<subvolume>\fR is not a
 subvolume, \fBbtrfs\fR returns an error.
+If \fI-R\fR is given, the subvolumes were removed recursively (otherwise it is
+not possible to remove a subvolume with a nested one); the -R switch requires
+the root capability.
