+The [GitLab Kubernetes Agent](https://gitlab.com/gitlab-org/cluster-integration/gitlab-agent) ("Agent", for short)
+is an active in-cluster component for connecting Kubernetes clusters to GitLab safely to support cloud-native deployment, management, and monitoring.
 
-- GitLab integration with a Kubernetes cluster behind a firewall or NAT
-  (network address translation).
-- Pull-based GitOps deployments.
-- [Inventory object](../../infrastructure/clusters/deploy/inventory_object.md) to keep track of objects applied to your cluster.
-- Real-time access to API endpoints in a cluster.
-- Alert generation based on [Container network policy](../../application_security/policies/index.md#container-network-policy).
-- [CI/CD Tunnel](ci_cd_tunnel.md) that enables users to access Kubernetes clusters from GitLab CI/CD jobs even if there is no network connectivity between GitLab Runner and a cluster.
+The Agent is installed into the cluster through code, providing you with a fast, safe, stable, and scalable solution.
 
-Many more features are planned. Please review [our roadmap](https://gitlab.com/groups/gitlab-org/-/epics/3329)
-and [our development documentation](https://gitlab.com/gitlab-org/cluster-integration/gitlab-agent/-/tree/master/doc).
+With GitOps, you can manage containerized clusters and applications from a Git repository that:
 
-## GitLab Agent GitOps workflow
+- Is the single source of truth of your system.
+- Is the single place where you operate your system.
+- Is a single resource to monitor your system.
 
-The GitLab Agent, herein _Agent_, uses multiple GitLab projects to provide a flexible workflow
+By combining GitLab, Kubernetes, and GitOps, it results in a robust infrastructure:
+
+- GitLab as the GitOps operator.
+- Kubernetes as the automation and convergence system.
+- GitLab CI/CD as the Continuous Integration and Continuous Deployment engine.
+
+Beyond that, you can use all the features offered by GitLab as
+the all-in-one DevOps platform for your product and your team.
+
+## Agent's features
+
+By using the GitLab Kubernetes Agent, you can:
+
+- Connect GitLab with a Kubernetes cluster behind a firewall or a
+Network Address Translation (NAT).
+- Have real-time access to API endpoints in your cluster from GitLab CI/CD.
+- Use GitOps to configure your cluster through the [Agent's repository](repository.md).
+- Perform pull-based or push-based GitOps deployments.
+- Configure [Network Security Alerts](#kubernetes-network-security-alerts)
+based on [Container Network Policies](../../application_security/policies/index.md#container-network-policy).
+- Track objects applied to your cluster through [inventory objects](../../infrastructure/clusters/deploy/inventory_object.md).
+- Use the [CI/CD Tunnel](ci_cd_tunnel.md) to access Kubernetes clusters
+from GitLab CI/CD jobs while keeping the cluster's APIs safe and unexposed
+to the internet.
+- [Deploy the GitLab Runner in a Kubernetes cluster](https://docs.gitlab.com/runner/install/kubernetes-agent.html).
+
+See the [GitLab Kubernetes Agent roadmap](https://gitlab.com/groups/gitlab-org/-/epics/3329) to track its development.

-There are several components that work in concert for the Agent to accomplish GitOps deployments:
-
-- A properly-configured Kubernetes cluster where the Agent is running.
-- A configuration repository that contains a `config.yaml` file, which tells the
-  Agent the repositories to synchronize with the cluster.
-- A manifest repository that contains manifest files. Any changes to manifest files are applied to the cluster.
-
-You can use the same GitLab project or projects for configuration and manifest files, as follows:
-
-- Single GitLab project (recommended): when you use a single repository to hold both the manifest and the configuration files, these projects can be either private or public, as you prefer.
-- Two GitLab projects: when you opt to use two different GitLab projects, one for manifest files, and another for configuration files, the manifests project must be public, while the configuration project can be either private or public. Our backlog contains issues for adding support for
-[private manifest repositories outside of the configuration project](https://gitlab.com/gitlab-org/gitlab/-/issues/220912) and
-[group level agents](https://gitlab.com/gitlab-org/gitlab/-/issues/283885) in the future.
-
-For more details, please refer to our [full architecture documentation](https://gitlab.com/gitlab-org/cluster-integration/gitlab-agent/-/blob/master/doc/architecture.md#high-level-architecture) in the Agent project.
-
-## Get started with GitOps and the GitLab Agent
-
-The setup process involves a few steps to enable GitOps deployments:
-
-1. [Set up the Kubernetes Agent Server](#set-up-the-kubernetes-agent-server) for your GitLab instance.
-1. [Define a configuration repository](#define-a-configuration-repository).
-1. [Create an Agent record in GitLab](#create-an-agent-record-in-gitlab).
-1. [Install the Agent into the cluster](#install-the-agent-into-the-cluster).
-1. [Generate and copy a Secret token used to connect to the Agent](#create-the-kubernetes-secret).
-1. [Create manifest files](#create-manifest-files).

-
-### Upgrades and version compatibility
-
-As the GitLab Kubernetes Agent is a new product, we are constantly adding new features
-to it. As a result, while shipped features are production ready, its internal API is
-neither stable nor versioned yet. For this reason, GitLab only guarantees compatibility
-between corresponding major.minor (X.Y) versions of GitLab and its cluster side
-component, `agentk`.
-
-Upgrade your agent installations together with GitLab upgrades. To decide which version of `agentk` to install follow:
-
-1. Open the [`GITLAB_KAS_VERSION`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/GITLAB_KAS_VERSION) file from the GitLab Repository, which contains the latest `agentk` version associated with the `master` branch.
-1. Change the `master` branch and select the Git tag associated with your version. For instance, you could change it to GitLab [v13.5.3-ee release](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.5.3-ee/GITLAB_KAS_VERSION)
-
-The available `agentk` and `kas` versions can be found in
-[the container registry](https://gitlab.com/gitlab-org/cluster-integration/gitlab-agent/container_registry/).
-
-### Set up the Kubernetes Agent Server
-
-> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/3834) in [GitLab Premium](https://about.gitlab.com/pricing/) 13.10, the GitLab Kubernetes Agent Server (KAS) became available on GitLab.com under `wss://kas.gitlab.com`.
-
-To use the KAS:
-
-- If you are a self-managed user, follow the instructions to [install the Kubernetes Agent Server](../../../administration/clusters/kas.md).
-- If you are a GitLab.com user, when you [set up the configuration repository](#define-a-configuration-repository) for your agent, use `wss://kas.gitlab.com` as the `--kas-address`.
-
-### Define a configuration repository
-
-> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/259669) in GitLab 13.7, the Agent manifest configuration can be added to multiple directories (or subdirectories) of its repository.
-> - Group authorization was [introduced](https://gitlab.com/groups/gitlab-org/-/epics/5784) in GitLab 14.3.
-
-To configure an Agent, you need:
-
-1. A GitLab repository to hold the configuration file.
-1. Install the Agent in a cluster.
-
-After installed, when you update the configuration file, GitLab transmits the
-information to the cluster automatically without downtime.
-
-In your repository, add the Agent configuration file under:
-
-```plaintext
-.gitlab/agents/<agent-name>/config.yaml
-```
-
-Your `config.yaml` file specifies all configurations of the Agent, such as:
-
-- The manifest projects to synchronize.
-- The groups that can access this Agent via the [CI/CD Tunnel](ci_cd_tunnel.md).
-- The address of the `hubble-relay` for the Network Security policy integrations.
-
-As an example, a minimal Agent configuration that sets up only the manifest
-synchronizations is:
-
-```yaml
-gitops:
-  manifest_projects:
-  - id: "path-to/your-manifest-project-1"
-    paths:
-    - glob: '/**/*.{yaml,yml,json}'
-```
-
-All the options for the [Kubernetes Agent configuration repository](repository.md) are documented separately.
-
-### Create an Agent record in GitLab
-
-> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/5786) in GitLab 14.1, you can create a new Agent record directly from the GitLab UI.
-
-Next, create a GitLab Rails Agent record to associate it with
-the configuration repository project. Creating this record also creates a Secret needed to configure
-the Agent in subsequent steps.
-
-In GitLab:
-
-1. From your project's sidebar, select **Infrastructure > Kubernetes clusters**.
-1. Select the **GitLab Agent managed clusters** tab.
-1. Select **Integrate with the GitLab Agent**.
-1. From the **Select an Agent** dropdown menu, select the Agent you want to connect and select **Next** to access the installation form.
-1. The form reveals your registration token. Securely store this secret token as you cannot view it again.
-1. Copy the command under **Recommended installation method**.
-
-In your computer:
-
-1. Open your local terminal and connect to your cluster.
-1. Run the command you copied from the installation form.
-
-### Install the Agent into the cluster
-
-To install the in-cluster component of the Agent, first you need to define a namespace. To create a new namespace,
-for example, `gitlab-kubernetes-agent`, run:
-
-```shell
-kubectl create namespace gitlab-kubernetes-agent
-```
-
-To perform a one-liner installation, run the command below. Make sure to replace:
-
-- `your-agent-token` with the token received from the previous step (identified as `secret` in the JSON output).
-- `gitlab-kubernetes-agent` with the namespace you defined in the previous step.
-- `wss://kas.gitlab.example.com` with the configured access of the Kubernetes Agent Server (KAS). For GitLab.com users, the KAS is available under `wss://kas.gitlab.com`.
-- `--agent-version=vX.Y.Z` with the latest released patch version matching your GitLab installation's major and minor versions. For example, for GitLab v13.9.0, use `--agent-version=v13.9.1`. You can find your GitLab version under the "Help/Help" menu.
-
-```shell
-docker run --pull=always --rm registry.gitlab.com/gitlab-org/cluster-integration/gitlab-agent/cli:stable generate --agent-token=your-agent-token --kas-address=wss://kas.gitlab.example.com --agent-version=vX.Y.Z --namespace gitlab-kubernetes-agent | kubectl apply -f -
-```
-
-WARNING:
-`--agent-version stable` can be used to refer to the latest stable release at the time when the command runs. It's fine for
-testing purposes but for production please make sure to specify a matching version explicitly.
-
-To find out the various options the above Docker container supports, run:
-
-```shell
-docker run --pull=always --rm registry.gitlab.com/gitlab-org/cluster-integration/gitlab-agent/cli:stable generate --help
-```
-
-#### Advanced installation
-
-For more advanced configurations, we recommend to use [the `kpt` based installation method](https://gitlab.com/gitlab-org/cluster-integration/gitlab-agent/-/tree/master/build/deployment/gitlab-agent).
-
-Otherwise, follow the manual installation steps described below.
-
-### Create the Kubernetes secret
-
-After generating the token, you must apply it to the Kubernetes cluster.
-
-To create your Secret, run:
-
-```shell
-kubectl create secret generic -n gitlab-kubernetes-agent gitlab-kubernetes-agent-token --from-literal=token='YOUR_AGENT_TOKEN'
-```
-
-The following example file contains the
-Kubernetes resources required for the Agent to be installed. You can modify this
-example [`resources.yml` file](#example-resourcesyml-file) in the following ways:
-
-- Replace `namespace: gitlab-kubernetes-agent` with `namespace: <YOUR-DESIRED-NAMESPACE>`.
-- You can configure `kas-address` (Kubernetes Agent Server) in several ways.
-  The agent can use the WebSockets or gRPC protocols to connect to the Agent Server.
-  Select the option appropriate for your cluster configuration and GitLab architecture:
-  - The `wss` scheme (an encrypted WebSockets connection) is specified by default
-    after you install the `gitlab-kas` sub-chart, or enable `gitlab-kas` for Omnibus GitLab.
-    When using the sub-chart, you must set `wss://kas.host.tld:443` as
-    `kas-address`, where `host.tld` is the domain you've setup for your GitLab installation.
-    When using Omnibus GitLab, you must set `wss://GitLab.host.tld:443/-/kubernetes-agent/` as
-    `kas-address`, where `GitLab.host.tld` is your GitLab hostname.
-  - When using the sub-chart, specify the `ws` scheme (such as `ws://kas.host.tld:80`)
-    to use an unencrypted WebSockets connection.
-    When using the Omnibus GitLab, specify the `ws` scheme (such as `ws://GitLab.host.tld:80/-/kubernetes-agent/`).
-  - Specify the `grpc` scheme if both Agent and Server are installed in one cluster.
-    In this case, you may specify `kas-address` value as
-    `grpc://gitlab-kas.<your-namespace>:8150`) to use gRPC directly, where `gitlab-kas`
-    is the name of the service created by `gitlab-kas` chart, and `<your-namespace>`
-    is the namespace where the chart was installed.
-  - Specify the `grpcs` scheme to use an encrypted gRPC connection.
-  - When deploying KAS through the [GitLab chart](https://docs.gitlab.com/charts/), it's possible to customize the
-    `kas-address` for `wss` and `ws` schemes to whatever you need.
-    Check the [chart's KAS Ingress documentation](https://docs.gitlab.com/charts/charts/gitlab/kas/#ingress)
-    to learn more about it.
-  - In the near future, Omnibus GitLab intends to provision `gitlab-kas` under a sub-domain by default, instead of the `/-/kubernetes-agent/` path. Please follow [this issue](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/5784) for details.
-- If you defined your own secret name, replace `gitlab-kubernetes-agent-token` with your
-  secret name in the `secretName:` section.
-
-To apply this file, run the following command:
-
-```shell
-kubectl apply -n gitlab-kubernetes-agent -f ./resources.yml
-```
-
-To review your configuration, run the following command:
-
-```shell
-$ kubectl get pods -n gitlab-kubernetes-agent
-
-NAMESPACE                NAME                                          READY   STATUS    RESTARTS   AGE

-### Create manifest files
-
-In a previous step, you configured a `config.yaml` to point to the GitLab projects

-project, and public projects. Support for other private projects is
-planned in the issue [Agent authorization for private manifest
-projects](https://gitlab.com/gitlab-org/gitlab/-/issues/220912).
-
-Each time you push a change to a monitored manifest repository, the Agent logs the change:
