-# Datree
-
-[Datree](https://www.datree.io/) (pronounced `/da-tree/`) secures your Kubernetes by blocking the deployment of misconfigured resources.
+# Datree [DEPRECATED]
 
-## ✌️ Quick-start in two steps
+[Datree](https://www.datree.io/) (pronounced `/da-tree/`) was built to secure Kubernetes workloads by blocking the deployment of misconfigured resources. **Since July 2023, the commercial company that supports and actively maintains this project has been closed.**
 
-Install Datree to get insights on the status of your cluster and enforce your desired policies on new resources.
+## Migrating to the (fully) open-source version of Datree 
 
-> **NOTE:**  
-> By default, Datree does not block misconfigured resources, it only monitors and alerts about them.  
-> To enable **enforcement mode**, see the [documentation](https://hub.datree.io/setup/behavior#options).
+For existing users, it is still possible to run Datree as a standalone: https://hub.datree.io/cli/offline-mode
 
-### 1. Add the Datree Helm repository
-Run the following command in your terminal:
-```terminal
-helm repo add datree-webhook https://datreeio.github.io/admission-webhook-datree
-helm repo update
-```
+## What will not be available anymore
 
-### 2. Install Datree on your cluster
-Replace `<DATREE_TOKEN>` with the token from your [dashboard](https://app.datree.io/), and run the following command in your terminal:
-
-```terminal
-helm install -n datree datree-webhook datree-webhook/datree-admission-webhook --debug \
---create-namespace \
---set datree.token=<DATREE_TOKEN> \
---set datree.clusterName=$(kubectl config current-context)
-```
-
-This will create a new namespace (datree), where Datree’s services and application resources will reside. `datree.token` is used to connect your dashboard to your cluster. Note that the installation can take up to 5 minutes.

-Datree also supports installation via **ArgoCD**, **Flux** and **Openshift**. See our [documentation](https://hub.datree.io/) for instructions.
+All the archived open source repositories under datreeio org will no longer be maintained and accept any new code changes, including any security patches.
+In addition, the following key capabilities will not longer be available anymore:  
+* Centralized policy registry
+* Automatic Kubernetes schema validation
+* Access to the dashboard and all of its components (e.g. activity-log page, token management, etc.)
 
 ## ⚙️ How it works
 
@@ -64,35 +39,8 @@ Datree comes with over 100 rules covering various use-cases, such as workload se
 
 In addition to our built-in rules, you can write [any custom rule you wish](https://hub.datree.io/custom-rules-overview) and then run it against your Kubernetes configurations to check for rule violations. Custom rules can be written in [JSON schema](https://hub.datree.io/custom-rules/custom-rules-overview) or in [Rego](https://hub.datree.io/custom-rules/rego-support).
 
-## 📊 Management dashboard (web application)
-
-Datree's dashboard provides valuable information about your clusters' health and stability. It details the resources that failed your policy checks, and shows you how to fix each violation.
-
-Datree can be configured via code or via the dashboard. The dashboard offers the following capabilities in an intuitive visual interface: 
-* Control Datree's configuration:
-  * Default action on failure - set whether resources that failed the policy check should be blocked or only monitored
-  * Set which policy to use for your checks
-  * Define resources and/or namespaces to ignore
-* Create & customize policies
-* Edit rules' failure message
-* Issue tokens
-* View policy check history
-* Configure Kubernetes schema version

-## 🤩 Additional features
-
-Datree offers a suite of features to make adoption seamless:
-* **Monitoring** - By default, Datree is installed in monitoring mode and does not block deployments until you decide to do so.
-* [**CLI**](https://hub.datree.io/cli/getting-started) - Help your developers find misconfigurations in their configs before deploying them, by integrating Datree into their CI.
-* **Simple integrations** - Datree works seamlessly with popular CD tools such as ArgoCD and FluxCD, and comes with ready-made integrations for various CI platforms.
-* **Cluster score** - Rank the stability of your cluster based on the number of detected misconfigurations.
