-## Quick Start guide
+## Getting Started
 
-### Step 1. Deploy Kubernetes operator using all in one config file
+### Supported features
 
-```
-kubectl apply -f https://raw.githubusercontent.com/mongodb/mongodb-atlas-kubernetes/main/deploy/all-in-one.yaml
-```
+* Create and configure an Atlas Project, or connect to an existing one.
+* Deploy, manage, scale, and tear down Atlas clusters.
+* Support for Atlas serverless instances.
+* Create and edit database users.
+* Manage IP Access Lists, network peering and private endpoints.
+* Configure and control Atlas’s fully managed cloud backup.
+* Configure federated authentication for your Atlas organization
+* Integrate Atlas monitoring with Prometheus.
 
-### Step 2. Create Atlas Deployment
+... and more.
 
-**1.** Create an Atlas API Key Secret
+To view the list of custom resources and their respective schemas, visit our [reference](https://www.mongodb.com/docs/atlas/operator/stable/custom-resources/) 
+documentation. See the [Quickstart](https://www.mongodb.com/docs/atlas/operator/stable/ak8so-quick-start/) to get started
+with Atlas Kubernetes Operator.
 
-In order to work with the Atlas Operator you need to
-provide [authentication information](https://docs.atlas.mongodb.com/configure-api-access)
-to allow the Atlas Operator to communicate with Atlas API. Once you have generated a Public and Private key in Atlas,
-you can create a Kuberentes Secret with:
-
-```
-kubectl create secret generic mongodb-atlas-operator-api-key \
-         --from-literal='orgId=<the_atlas_organization_id>' \
-         --from-literal='publicApiKey=<the_atlas_api_public_key>' \
-         --from-literal='privateApiKey=<the_atlas_api_private_key>' \
-         -n mongodb-atlas-system
-
-kubectl label secret mongodb-atlas-operator-api-key atlas.mongodb.com/type=credentials -n mongodb-atlas-system
-```
-
-**2.** Create an `AtlasProject` Custom Resource
-
-The `AtlasProject` CustomResource represents Atlas Projects in our Kubernetes cluster. You need to specify
-`projectIpAccessList` with the IP addresses or CIDR blocks of any hosts that will connect to the Atlas Deployment.
-
-```
-cat <<EOF | kubectl apply -f -
-apiVersion: atlas.mongodb.com/v1
-kind: AtlasProject
-metadata:
-  name: my-project
-spec:
-  name: Test Atlas Operator Project
-  projectIpAccessList:
-    - ipAddress: "192.0.2.15"
-      comment: "IP address for Application Server A"
-    - cidrBlock: "203.0.113.0/24"
-      comment: "CIDR block for Application Server B - D"
-EOF
-```
-
-**3.** Create an `AtlasDeployment` Custom Resource.
-
-The example below is a minimal configuration to create an M10 Atlas deployment in the AWS US East region. For a full list
-of properties, check
-`atlasdeployments.atlas.mongodb.com` [CRD specification](config/crd/bases/atlas.mongodb.com_atlasdeployments.yaml)):
-
-```
-cat <<EOF | kubectl apply -f -
-apiVersion: atlas.mongodb.com/v1
-kind: AtlasDeployment
-metadata:
-  name: my-atlas-deployment
-spec:
-  projectRef:
-    name: my-project
-  deploymentSpec:
-    name: test-deployment
-    providerSettings:
-      instanceSizeName: M10
-      providerName: AWS
-      regionName: US_EAST_1
-EOF
-```
-
-**4.** Create a database user password Kubernetes Secret
-
-```
-kubectl create secret generic the-user-password --from-literal='password=P@@sword%'
-
-kubectl label secret the-user-password atlas.mongodb.com/type=credentials
-```
-
-(note) To create X.509 user please see [this doc](docs/x509-user.md).
-
-**5.** Create an `AtlasDatabaseUser` Custom Resource
-
-In order to connect to an Atlas Deployment the database user needs to be created. `AtlasDatabaseUser` resource should
-reference the password Kubernetes Secret created in the previous step.
-
-```
-cat <<EOF | kubectl apply -f -
-apiVersion: atlas.mongodb.com/v1
-kind: AtlasDatabaseUser
-metadata:
-  name: my-database-user
-spec:
-  roles:
-    - roleName: "readWriteAnyDatabase"
-      databaseName: "admin"
-  projectRef:
-    name: my-project
-  username: theuser
-  passwordSecretRef:
-    name: the-user-password
-EOF
-```
-
-**6.** Wait for the `AtlasDatabaseUser` Custom Resource to be ready
-
-Wait until the AtlasDatabaseUser resource gets to "ready" status (it will wait until the deployment is created that may
-take around 10 minutes):
-
-```
-kubectl get atlasdatabaseusers my-database-user -o=jsonpath='{.status.conditions[?(@.type=="Ready")].status}'
-True
-```
-
-### Step 3. Connect your application to the Atlas Deployment
-
-The Atlas Operator will create a Kubernetes Secret with the information necessary to connect to the Atlas Deployment
-created in the previous step. An application in the same Kubernetes Cluster can mount and use the Secret:
-
-```
-...
-containers:
-- name: test-app
-  env:
-    - name: "CONNECTION_STRING"
-      valueFrom:
-        secretKeyRef:
-          name: test-atlas-operator-project-test-cluster-theuser
-          key: connectionStringStandardSrv
-
-```
-
-## Additional information or features

-In certain cases you can modify the default operator behaviour via [annotations](docs/annotations.md).
-
-Operator support Third Party Integration.
