 ## About
 
 The Qlik Sense installer CLI (qliksense) provides an imperative interface to many of the configurations that need to be applied against the declarative structure described in [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s). This cli facilitates:
@@ -31,120 +23,3 @@ For each version of a qliksense edge build there should be a corresponding relea
   - backup/restore operations
   - fully support airgap installation of QSEoK
   - restore unwanted deletion of kubernetes resources
-
-## Getting Started
-
-### Requirements
-
-- `kubectl` need to be installed and configured properly so that `kubectl` can connect to the kubernetes cluser. The `qliksense` CLI uses `kubectl` under the hood to perform operations on cluster
-  - (Docker Desktop setup tested for these instructions)
-  
-### Download
-
-- Download the appropriate executable for your platform from the [releases page](https://github.com/qlik-oss/sense-installer/releases) and rename it to `qliksense`. All the examplease down below uses `qliksense`.
-  
-### TL;DR
-
-- To download the version `v0.0.2` from qliksense-k8s [releases](https://github.com/qlik-oss/qliksense-k8s/releases).
-
-```shell
-$qliksense fetch v0.0.2
-```
-
-- To install CRDs for QSEoK and qliksense operator into the kubernetes cluster.
-
-```shell
-$qliksense crds install --all
-```
-
-- To install QSEoK into a namespace in the kubernetes cluster where `kubectl` is pointing to.
-
-```shell
-$qliksense install --acceptEULA="yes"
-```
-
-## How qliksense cli works
-
-At the initialization `qliksense` cli create few files in the director `~/.qliksene` and it contains following files
-
-```console
-.qliksense
-├── config.yaml
-├── contexts
-│   └── qlik-default
-│       └── qlik-default.yaml
-└── ejson
-    └── keys
-```
-
-`qlik-default.yaml` is a default CR has been created with some default values like this
-
-```yaml
-apiVersion: qlik.com/v1
-kind: Qliksense
-metadata:
-  name: qlik-default
-spec:
-  profile: docker-desktop
-  secrets:
-    qliksense:
-    - name: mongoDbUri
-      value: mongodb://qlik-default-mongodb:27017/qliksense?ssl=false
-  rotateKeys: "yes"
-  releaseName: qlik-default
-```
-
-The `qliksense` cli creates a default qliksense context (different from kubectl context) named `qlik-default` which will be the prefix for all kubernetes resources created by the cli under this context latter on. New context and configuration can be created by the cli.
-
-```console
-$ qliksense config -h
-do operations on/around CR
-
-Usage:
-  qliksense config [command]
-
-Available Commands:
-  apply         generate the patchs and apply manifests to k8s
-  list-contexts retrieves the contexts and lists them
-  set           configure a key value pair into the current context
-  set-configs   set configurations into the qliksense context as key-value pairs
-  set-context   Sets the context in which the Kubernetes cluster and resources live in
-  set-secrets   set secrets configurations into the qliksense context as key-value pairs
-  view          view the qliksense operator CR
-
-Flags:
-  -h, --help   help for config
-
-Use "qliksense config [command] --help" for more information about a command.
-```
-
-`qliksense` cli works in two modes
-
-- with a git repo fork/clone of [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s)
-- without git repo
-
-### Without git repo
-
-In this mode `qliksense` CLI download the specified version from [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s) and put it into folder `~/.qliksense/contexts/<context-name>/qlik-k8s`.

-The qliksense cli create a CR for the qliksense operator and all the config operations are peformed to edit the CR. So when `qliksense install` or `qliksense config apply` both generate patches in local file system (i.e `~/.qliksense/contexts/<context-name>/qlik-k8s`) and install those manifests into the cluster and create a custom resoruce (CR) for the `qliksene operator` then the operator make association to the isntalled resoruces  so that when `qliksenes uninstall` is performed the operator can delete all those kubernetes resources related to QSEoK for the current context.
-
-### With a git repo
-
-User has to create fork or clone of [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s) and push it to their own git server. When user perform `qliksense install` or `qliksene config apply` the qliksense operator do these tasks
-
-- downloads the corresponding version of manifests from the user's git repo.
-- generate kustomize patches
-- install kubernetes resoruces 
-- push those generated patches into a new branch in the provided git repo. so that user user can merge those patches into their master branch. 
-- spinup a cornjob to monitor master branch. If user modifies anything in the master branch those changes will be applied into the cluster. This is a light weight `git-ops` model
-
-This is how repo info is provided into the CR
-
-```console
-qliksense config set git.repository="https://github.com/my-org/qliksense-k8s"
-
-qliksense config set git.accessToken=blablalaala

-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`:

+# How qliksense cli works
+
+At the initialization, `qliksense` cli creates few files in the director `~/.qliksene` and it contains following files:
+
+```console
+.qliksense
+├── config.yaml
+├── contexts
+│   └── qlik-default
+│       └── qlik-default.yaml
+└── ejson
+    └── keys
+```
+
+`qlik-default.yaml` is a default CR created with some default values like:
+
+```yaml
+apiVersion: qlik.com/v1
+kind: Qliksense
+metadata:
+  name: qlik-default
+spec:
+  profile: docker-desktop
+  secrets:
+    qliksense:
+    - name: mongoDbUri
+      value: mongodb://qlik-default-mongodb:27017/qliksense?ssl=false
+  rotateKeys: "yes"
+  releaseName: qlik-default
+```
+
+The `qliksense` cli creates a default qliksense context (different from kubectl context) named `qlik-default` which will be the prefix for all kubernetes resources created by the cli under this context later on. 
+
+New context and configuration can be created by the cli, get available commands using:
+
+```console
+qliksense config -h
+```
+
+---
+
+`qliksense` cli works in two modes
+
+- With a git repo fork/clone of [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s)
+- Without git repo
+
+## Without git repo
+
+In this mode `qliksense` CLI downloads the specified version from [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s) and places it in `~/.qliksense/contexts/<context-name>/qlik-k8s` folder.
+
+The qliksense cli creates a CR for the QlikSense operator and all config operations are peformed to edit the CR.
+
+`qliksense install` or `qliksense config apply` will generate patches in local file system (i.e `~/.qliksense/contexts/<context-name>/qlik-k8s`) and
+
+- Install those manifests into the cluster 
+- Create a custom resoruce (CR) for the `qliksene operator`.
+
+The operator makes the association to the installed resoruces so that when `qliksense uninstall` is performed the operator can delete all kubernetes resources related to QSEoK for the current context.
+
+## With a git repo
+
+Create a fork or clone of [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s) and push it to your git repo/server
+
+To add your repo into CR, perform the following:
+
+```bash
+qliksense config set git.repository="https://github.com/my-org/qliksense-k8s"
+qliksense config set git.accessToken="<mySecretToken>"
+```
+
+When you perform `qliksense install` or `qliksene config apply`, qliksense operator performs these tasks:
+
+- Download corresponding version of manifests from the your git repo
+- Generate kustomize patches
+- Install kubernetes resources
+- Push generated patches into a new branch in the provided git repo. _Gives you ability to merge patches into your master branch_
+- Create a CronJob to monitor master branch. Any changes pushed to master branch will be applied into the cluster. _This is a light weight `git-ops` model_
+
+## GitOps
+
+To enable gitops, the following section should be in the CR
+
+```yaml
+....
+spec:
+  git:
+    repository: https://github.com/<OWNER>/<REPO>
+    accessToken: "<git-token>"
+    userName: "<git-username>"
+  gitOps:
+    enabled: "yes"
+    schedule: "*/5 * * * *"
+    watchBranch: <myBranch>

+# Overview
+
+The Qlik Sense installer CLI (`qliksense`) provides an imperative interface to many of the configurations that need to be applied against the declarative structure described in [qliksense-k8s](https://github.com/qlik-oss/qliksense-k8s). This cli facilitates:
+

+##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
+
+Preflight service check
+-----------------------
+
+Preflight service check: 
+Created service "svc-pf-check"
+Preflight service creation check: PASSED
+Cleaning up resources...
+Deleted service: svc-pf-check
+Completed preflight service check
+```
+
+### 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
+Cleaning up resources...
+Deleted deployment: deployment-preflight-check
+Completed preflight deployment check
+```
+
+### Pod check
+We use the commmand below to test if we are able to create a pod in the cluster.
+```console
+$ qliksense preflight pod
+
+Preflight pod check
+--------------------
+
+Preflight pod check: 
+Created pod: pod-pf-check
+Preflight pod creation check: PASSED
+Cleaning up resources...
+Deleted pod: pod-pf-check
+Completed preflight pod check
+```
+
+### Running all checks
+Run the command shown below to execute all preflight checks.
+```console
+$ qliksense preflight all
+
+Running all preflight checks
+
+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
+
+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
+...
+...
+All preflight checks have PASSED
+Completed running all preflight checks
+
+```
