+# MongoDB Community Operator and Instance Chart
+=============================================
+This chart installs the MongoDB Community Operator, deploys a MongoDB Community replica set, and automatically registers MongoDB connection details and credentials into AWS Secrets Manager so that SLS (and MAS) can consume them.
+
+<!--docs-include-start-->
+
+## Overview
+
+This chart provisions a MongoDB Community Operator and a 3-node MongoDB Community replica set within the specified namespace (default: `mongoce`). It creates the necessary operator group, subscriptions, admin credential secrets, and stateful replica set. Additionally, it executes a post-sync job that automatically formats and pushes connection details, credentials, and TLS certificates to AWS Secrets Manager (`${ACCOUNT_ID}/${CLUSTER_ID}/mongo`) for seamless integration with IBM SLS and MAS.
+
+## Prerequisites
+
+- OpenShift Cluster 4.12+
+- `community-operators` CatalogSource enabled in `openshift-marketplace`
+- ArgoCD / OpenShift GitOps with Cluster Admin privileges
+- AWS Secrets Manager access credentials configured in the cluster environment
+
+## Resources Created
+
+| Resource Type | Resource Name | Namespace | Condition | Installed By |
+|---|---|---|---|---|
+| `Namespace` | `mongoce` | - | Always | `cluster_admin_role` |
+| `OperatorGroup` | `mongodb-operator-group` | `mongoce` | Always | `cluster_admin_role` |
+| `Subscription` | `mongodb-kubernetes-operator` | `mongoce` | Always | `cluster_admin_role` |
+| `Secret` | `admin-user-credentials` | `mongoce` | Always | `cluster_admin_role` |
+| `MongoDBCommunity` | `mas-mongo-ce` | `mongoce` | Always | `cluster_admin_role` |
+| `Secret` | `mongo-aws-creds` | `mongoce` | When `run_sync_hooks` and `cluster_admin_role` | `cluster_admin_role` |
+| `Job` | `postsync-mongo-update-sm-job-*` | `mongoce` | When `run_sync_hooks` and `cluster_admin_role` | `cluster_admin_role` |
+
+## Configuration
+
+This chart accepts the following configuration values in the ArgoCD Application values:
+
+```yaml
+mongodb_ce:
+  install: "true"
+  channel: "v0.7"
+  install_plan: "Automatic"
+  source: "community-operators"
+  source_namespace: "openshift-marketplace"
+  namespace: "mongoce"
+  instance_name: "mas-mongo-ce"
+  version: "7.0.5"
+  members: 3
+  admin_password: "<path:secret#password>"
+  storage_size: "10Gi"
+  storage_class: ""
+```
+
+## Base Cluster Values
+
+This chart inherits common cluster configuration values. For complete documentation of all base cluster values including optional fields like `notifications`, `custom_labels`, `devops`, and `cli_image_repo`, see the [Cluster Base Values Reference](../../docs/reference/cluster-base-values.md).
+
+## Examples
+
+### Basic MongoDB Community Deployment
+
+```yaml
+merge-key: "my-account/my-cluster"
+mongodb_ce:
+  install: "true"
+  members: 3
+  version: "7.0.5"
+  storage_size: "10Gi"
+  admin_password: "<path:arn:aws:secretsmanager:us-west-2:123456789:secret:my-account/my-cluster/mongo#password>"
+```
+
+### Secrets Manager Integration
+
+Upon successful deployment of the MongoDB replica set, the post-sync Job creates / updates the cluster secret at:
+`${ACCOUNT_ID}/${CLUSTER_ID}/mongo`
+
+With the following JSON payload:
+```json
+{
+  "docdb_host": "mas-mongo-ce-0.mas-mongo-ce-svc.mongoce.svc.cluster.local",
+  "docdb_port": "27017",
+  "username": "admin",
+  "password": "<admin_password>",
+  "info": "config:\n  hosts:\n    - host: mas-mongo-ce-0.mas-mongo-ce-svc.mongoce.svc.cluster.local\n      port: 27017\n    - host: mas-mongo-ce-1.mas-mongo-ce-svc.mongoce.svc.cluster.local\n      port: 27017\n    - host: mas-mongo-ce-2.mas-mongo-ce-svc.mongoce.svc.cluster.local\n      port: 27017\n  configDb: admin\n  authMechanism: DEFAULT\n"
+}
+```
+
+## Troubleshooting
+
+- **MongoDBCommunity CR not ready**: Verify that the operator pod in `mongoce` is running without OOM or storage binding errors.
+- **Post-sync Job failure**: Check the Job pod logs in `mongoce` namespace to verify AWS credentials and secret permissions.
