-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.

+# MinIO Batch Job
+MinIO Batch jobs is an MinIO object management feature that lets you manage objects at scale. Jobs currently supported by MinIO
+
+- Replicate objects between buckets on multiple sites
+
+Upcoming Jobs
+
+- Copy objects from NAS to MinIO
+- Copy objects from HDFS to MinIO
+
+## Replication Job
+To perform replication via batch jobs, you create a job. The job consists of a job description YAML that describes
+
+- Source location from where the objects must be copied from
+- Target location from where the objects must be copied to
+- Fine grained filtering is available to pick relevant objects from source to copy from
+
+MinIO batch jobs framework also provides
+
+- Retrying a failed job automatically driven by user input
+- Monitoring job progress in real-time
+- Send notifications upon completion or failure to user configured target
+
+Following YAML describes the structure of a replication job, each value is documented and self-describing.
+
+```yaml
+replicate:
+  apiVersion: v1
+  # source of the objects to be replicated
+  source:
+	type: TYPE # valid values are "minio"
+	bucket: BUCKET
+	prefix: PREFIX
+	# NOTE: if source is remote then target must be "local"
+	# endpoint: ENDPOINT
+	# credentials:
+	#   accessKey: ACCESS-KEY
+	#   secretKey: SECRET-KEY
+	#   sessionToken: SESSION-TOKEN # Available when rotating credentials are used
+
+  # target where the objects must be replicated
+  target:
+	type: TYPE # valid values are "minio"
+	bucket: BUCKET
+	prefix: PREFIX
+	# NOTE: if target is remote then source must be "local"
+	# endpoint: ENDPOINT
+	# credentials:
+	#   accessKey: ACCESS-KEY
+	#   secretKey: SECRET-KEY
+	#   sessionToken: SESSION-TOKEN # Available when rotating credentials are used
+
+  # optional flags based filtering criteria
+  # for all source objects
+  flags:
+	filter:
+	  newerThan: "7d" # match objects newer than this value (e.g. 7d10h31s)
+	  olderThan: "7d" # match objects older than this value (e.g. 7d10h31s)
+	  createdAfter: "date" # match objects created after "date"
+	  createdBefore: "date" # match objects created before "date"
+
+	  ## NOTE: tags are not supported when "source" is remote.
+	  # tags:
+	  #   - key: "name"
+	  #     value: "pick*" # match objects with tag 'name', with all values starting with 'pick'
+
+	  ## NOTE: metadata filter not supported when "source" is non MinIO.
+	  # metadata:
+	  #   - key: "content-type"
+	  #     value: "image/*" # match objects with 'content-type', with all values starting with 'image/'
+
+	notify:
+	  endpoint: "https://notify.endpoint" # notification endpoint to receive job status events
+	  token: "Bearer xxxxx" # optional authentication token for the notification endpoint
+
+	retry:
+	  attempts: 10 # number of retries for the job before giving up
+	  delay: "500ms" # least amount of delay between each retry
+```
+
+You can create and run multiple 'replication' jobs at a time there are no predefined limits set.
+
+## Batch Jobs Terminology
+
+### Job
+A job is the basic unit of work for MinIO Batch Job. A job is a self describing YAML, once this YAML is submitted and evaluated - MinIO performs the requested actions on each of the objects obtained under the described criteria in job YAML file.
+
+### Type
+Type describes the job type, such as replicating objects between MinIO sites. Each job performs a single type of operation across all objects that match the job description criteria.
+
+## Batch Jobs via Commandline
+[mc](http://github.com/minio/mc) provides 'mc batch' command to create, start and manage submitted jobs.
+
+```
+NAME:
+  mc batch - manage batch jobs
+
+USAGE:
+  mc batch COMMAND [COMMAND FLAGS | -h] [ARGUMENTS...]
+
+COMMANDS:
+  generate  generate a new batch job definition
+  start     start a new batch job
+  list, ls  list all current batch jobs
+  status    summarize job events on MinIO server in real-time
+  describe  describe job definition for a job
+```
+
+### Generate a job yaml
+```
+mc batch generate alias/ replicate
+```
