+### Minio with ZFS backend - FreeBSD
+
+This example assumes that you have a FreeBSD 10.x running
+
+#### Step *1* 
+
+As root on the FreeBSD edit `/etc/rc.conf`
+```
+zfs_enable="YES"
+```
+
+Start ZFS service
+```
+# service zfs start
+```
+
+```
+# dd if=/dev/zero of=/zfs bs=1M count=4000
+```
+
+Configure a loopback device on the `/zfs` file. 
+```
+# mdconfig -a -t vnode -f /zfs
+```
+
+Create zfs pool
+```
+# zpool create minio-example /dev/md0
+```
+
+```
+# df /minio-example
+Filesystem    512-blocks Used   Avail Capacity  Mounted on
+minio-example    7872440   38 7872402     0%    /minio-example
+```
+
+Verify if it is writable
+```
+# touch /minio-example/testfile
+# ls -l /minio-example/testfile
+-rw-r--r--  1 root  wheel  0 Apr 26 00:51 /minio-example/testfile
+```
+
+Now you have successfully created a ZFS pool for futher reading please refer to [ZFS Quickstart Guide](https://www.freebsd.org/doc/handbook/zfs-quickstart.html)
+
+However, this pool is not taking advantage of any ZFS features. To create a dataset on this pool with compression enabled:
+
+```
+# zfs create minio-example/compressed-objects
+# zfs set compression=gzip minio-example/compressed-objects
+```
+
+To keep monitoring your pool use
+
+```
+# zpool status
+  pool: minio-example
+ state: ONLINE
+  scan: none requested
+config:
+
+	NAME        STATE     READ WRITE CKSUM
+	minio-example  ONLINE       0     0     0
+	  md0       ONLINE       0     0     0
+
+errors: No known data errors
+```
+
+#### Step *2*
+
+Now start minio server on the ``/minio-example/compressed-objects``, change the permissions such that this directory is accessibly by a normal user
+
+```
+# chown -R minio-user:minio-user /minio-example/compressed-objects
+```
+
+Now login as ``minio-user`` and start minio server. 
+
+```
+$ curl https://dl.minio.io/server/minio/release/freebsd-amd64/minio > minio
+$ chmod 755 minio
+$ ./minio server /minio-example/compressed-objects
+
+AccessKey: X3RU3Q6B4T20TYB281W5  SecretKey: bvp0DF8c+6MzL60UxFqOZGlA5Z8UPfIAATUQuzLS  Region: us-east-1
+
+Minio Object Storage:
+    http://159.203.234.49:9000
+    http://10.12.0.5:9000
+    http://127.0.0.1:9000
+
+Minio Browser:
+    http://159.203.234.49:9000
+    http://10.12.0.5:9000
+    http://127.0.0.1:9000
+
+To configure Minio Client:
+    $ wget https://dl.minio.io/client/mc/release/freebsd-amd64/mc
+    $ chmod 755 mc
+    $ ./mc config host add myminio http://localhost:9000 X3RU3Q6B4T20TYB281W5 bvp0DF8c+6MzL60UxFqOZGlA5Z8UPfIAATUQuzLS
+```
+
+Point your browser to http://localhost:9000 and login with the credentials displayed on the command line. 
+
+Now you have a S3 compatible server running on top of your ZFS backend which transparently provides disk level compression for your uploaded objects.
+
+Thanks for using Minio, awaiting feedback :-)
