+    as of the date such litigation is filed.

+
+    (d) If the Work includes a "NOTICE" text file as part of its
+        distribution, then any Derivative Works that You distribute must

+        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

+    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

+    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.

+    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.

+## qliksense apply
+
+`qliksense apply` command takes input a cr file or input from pipe
+
+- `qliksense apply -f cr-file.yaml`
+- `cat cr-file.yaml | qliksense apply -f -`
+
+the content of `cr-file.yaml` should be something similar
+
+```yaml
+apiVersion: qlik.com/v1
+kind: Qliksense
+metadata:
+  name: qlik-test
+  labels:
+    version: v0.0.2
+spec:
+  configs:
+    qliksense:
+    - name: acceptEULA
+      value: "yes"
+  secrets:
+    qliksense:
+    - name: mongoDbUri
+      value: mongodb://qlik-test-mongodb:27017/qliksense?ssl=false
+  profile: docker-desktop
+  rotateKeys: "yes"
+  ```
+
+This will do everything `qliksense load` does and install the qliksense into the cluster. 
+
+## qliksense load
+
+`qliksense load` command takes input a cr file or input from pipe.
+
+- `qliksense load -f cr-file.yaml`
+- `cat cr-file.yaml | qliksense load -f -`
+
+This will load the CR into `${QLIKSENSE_HOME}` folder, create context structure and set the current context to that CR. 
+This will also encrypt the secrets from CR while writing the CR into the disk.
+
+## qliksense about
+
+About action will display inside information regarding [qliksense-k8](https://github.com/qlik-oss/qliksense-k8s) release.
+
+it will support following flags
+
+- `qliksense about 1.0.0` display default profile for tag `1.0.0`.
+- `qliksense about 1.0.0 --profile=docker-desktop`
+- `qliksense about` 
+  - assuming current directory has `manifests/docker-desktop`
+  - or get version information from pull of `qliksense-k8s` `master`
+
+using other supported commands user might have built the CR into the location `~/.qliksense/myqliksense.yaml`
+
+```yaml
+apiVersion: qlik.com/v1
+kind: QlikSense
+metadata:
+  name: myqliksense
+spec:
+  profile: docker-desktop
+  manifestsRoot: /Usr/ddd/my-k8-repo/manifests

+  storageClassName: efs
+  configs:

+      value: "yes"
+  secrets:
+    qliksense:
+    - name: mongoDbUri
+      value: "mongo://mongo:3307"
+    - name: messagingPassword
+      valueFromKey: messagingPassword
+```
+
+In that case the command would be
+
+- `qliksense about`
+   - display from `/Usr/ddd/my-k8-repo/manifests/docker-desktop` location
+   - pull from `master` if directory invalid/empty
+
+
+## qliksense config
+
+Config action will perform operations on configurations and contexts regarding the [qliksense-k8](https://github.com/qlik-oss/qliksense-k8s) release.
+
+it will support following commands:
+
+- `qliksense config apply` - generate the patchs and apply manifests to k8s
+- `qliksense config list-contexts` - retrieves the contexts and lists them
+- `qliksense config set` - configure a key value pair into the current context
+- `qliksense config set-configs` - set configurations into the qliksense context as key-value pairs
+- `qliksense config set-context` - sets the context in which the Kubernetes cluster and resources live in
+- `qliksense config set-secrets <service_name>.<attribute>="<value>" --secret=false` - set secrets configurations into the qliksense context as key-value pairs and show encrypted value as part of CR
+- `qliksense config set-secrets <service_name>.<attribute>="<value>" --secret=true` - set secrets configurations into the qliksense context as key-value pairs and show a key reference to the created Kubernetes secret resource as part of the CR
+- `qliksense config view` - view the qliksense operator CR
+- `qliksense config delete-context` - deletes a specific context locally (not in-cluster). Deletes context in spec of `config.yaml` and locally deletes entire folder of specified context (does not delete in-cluster secrets)
+
+
+the global file that abstracts all the contexts is `config.yaml`, located at:  `~/.qliksense/config.yaml`:
+```yaml
+apiVersion: config.qlik.com/v1

+##Preflight checks
+Preflight checks provide pre-installation cluster conformance testing and validation before we install qliksense on the cluster. We gather a suite of conformance tests that can be easily written and run on the target cluster to verify that cluster-specific requirements are met.
+The suite consists of a set of `collectors` which run the specifications of every test and `analyzers` which analyze the results of every test run by the collector.
+We support the following tests at the moment as part of preflight checks, and the range of the suite will be expanded in future.
+
+Run the following command to view help about the commands supported by preflight at any moment:
+```console
+$ qliksense preflight
+perform preflight checks on the cluster
+
+Usage:
+  qliksense preflight [command]
+
+Examples:
+qliksense preflight <preflight_check_to_run>
+
+Available Commands:
+  all         perform all checks
+  dns         perform preflight dns check
+  k8s-version check k8s version
+
+Flags:
+  -h, --help   help for preflight
+```
+
+### DNS check
+Run the following command to perform preflight DNS check. We setup a kubernetes deployment and try to reach it as part of establishing DNS connectivity in this check. 
+The expected output should be similar to the one shown below.
+```console
+$ qliksense preflight dns
+
+Preflight DNS check
+---------------------
+Created deployment "dep-dns-preflight-check"
+Created service "svc-dns-pf-check"
+Created pod: pf-pod-1
+Fetching pod: pf-pod-1
+Fetching pod: pf-pod-1
+Exec-ing into the container...
+Preflight DNS check: PASSED
+Completed preflight DNS check
+Cleaning up resources...
+Deleted pod: pf-pod-1
+Deleted service: svc-dns-pf-check
+Deleted deployment: dep-dns-preflight-check
+
+```
+
+### Kubernetes version check
+We check the version of the target kubernetes cluster and ensure that it falls in the valid range of kubernetes versions that are supported by qliksense. 
+The command to run this check and the expected similar output are as shown below:
+```console
+$ qliksense preflight k8s-version
+
+Preflight kubernetes minimum version check
+------------------------------------------
+Kubernetes API Server version: v1.15.5
+Current K8s Version: 1.15.5
+Current 1.15.5 is greater than minimum required version:1.11.0, hence good to go
+Preflight minimum kubernetes version check: PASSED
+Completed Preflight kubernetes minimum version check
+
+```
+
+### Service check
+We use the commmand below to test if we are able to create a service in the cluster.
+```console
+$ qliksense preflight service

+
+### Deployment check
+We use the commmand below to test if we are able to create a deployment in the cluster. After the test exexutes, we wait until the created deployment terminates before we exit the command. 
+```console
+$ qliksense preflight deployment
+
+Preflight deployment check
+-----------------------
+Preflight deployment check: 
+Created deployment "deployment-preflight-check"
+Preflight Deployment check: PASSED
