+      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

+          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

+      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.

 # SeaweedFS Operator
 
+This [Kubernetes Operator](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/) is made to easily deploy SeaweedFS onto your Kubernetes-Cluster.
+
+The difference to [seaweedfs-csi-driver](https://github.com/seaweedfs/seaweedfs-csi-driver) is that the infrastructure (SeaweedFS) itself runs on Kubernetes as well (Master, Filer, Volume-Servers) and can as such easily scale with it as you need. It is also by far more resilent to failures then a simple systemD service in regards to handling crashing services or accidental deletes.
+
+By using `make deploy` it will deploy a Resource of type 'Seaweed' onto your current kubectl $KUBECONFIG target (the operator itself) which by default will do nothing unless you configurate it (see examples in config/samples/).
+
+Goals: 
+- [x] Automatically deploy and manage a SeaweedFS cluster.
+- [x] Ability to be managed by other Operators.
+- [ ] Compability with [seaweedfs-csi-driver](https://github.com/seaweedfs/seaweedfs-csi-driver)
+- [x] Auto rolling upgrade and restart.
+- [x] Ingress for volume server, filer and S3, to support HDFS, REST filer, S3 API and cross-cluster replication.
+- [ ] Support all major cloud Kubernetes: AWS, Google, Azure.
+- [ ] Scheduled backup to cloud storage: S3, Google Cloud Storage , Azure.
+- [ ] Put warm data to cloud storage tier: S3, Google Cloud Storage , Azure.
+- [ ] Grafana dashboard.
+
 ## Installation
 
+This operator uses `kustomize` to deploy. The installation process will install one for you if you do not have one.
+
+By default, the defaulting and validation webhooks are disabled. We strongly recommend that the webhooks be enabled.
+
+First clone the repository:
+
+```bash
+$ git clone https://github.com/seaweedfs/seaweedfs-operator --depth=1
+```
+
+To deploy the operator with webhooks enabled, make sure you have installed the `cert-manager`(Installation docs: https://cert-manager.io/docs/installation/) in your cluster, then follow the instructions in the `config/default/kustomization.yaml` file to uncomment the components you need.
+
+Lastly, change the value of `ENABLE_WEBHOOKS` to `"true"` in `config/manager/manager.yaml`
+
+Afterwards fire up:
+```bash
+$ make install
+```
+
+Then run the command to deploy the operator into your cluster:
+
+```bash
+$ make deploy
+```
+
+Verify if it was correctly deployed with:
+```bash
+$ kubectl get pods --all-namespaces
+```
+
+Which may return:
+```bash
