 # Netdata Agent Installation
 
 Netdata is very flexible and can be used to monitor all kinds of infrastructure. Read more about possible [Deployment guides](/docs/deployment-guides/README.md) to understand what better suites your needs.
 
 ## Install through Netdata Cloud
 
-Netdata is a free and open-source (FOSS) monitoring agent that collects thousands of hardware and software metrics from any physical or virtual system (we call them _nodes_). These metrics are organized in an easy-to-use and -navigate interface.
-
-Netdata runs permanently on all your physical/virtual servers, containers, cloud deployments, and edge/IoT devices.
-It runs on Linux distributions (Ubuntu, Debian, CentOS, and more), container/microservice platforms (Kubernetes clusters, Docker), and many other operating systems (FreeBSD, macOS), with no `sudo` required.
+The easiest way to install Netdata on your system is via Netdata Cloud, to do so:
 
-To install Netdata in minutes on your platform:
+1. Sign up to <https://app.netdata.cloud/>.
+2. You will be presented with an empty space, and a prompt to "Connect Nodes" with the install command for each platform.
+3. Select the platform you want to install Netdata to, copy and paste the script into your node's terminal, and run it.

+Once Netdata is installed, you can see the node live in your Netdata Space and charts in the [Metrics tab](/docs/dashboards-and-charts/metrics-tab-and-single-node-tabs.md).
 
-Upon installation completing successfully, you should be able to see the node live in your Netdata Space and live charts in the Overview tab. [Take a look at our Dashboards and Charts](/docs/dashboards-and-charts/README.md) section to read more about Netdata's features.

-If Netdata didn't autodetect all the hardware, containers, services, or applications running on your node, you should learn more about [how data collectors work](/src/collectors/README.md). If there's a [supported collector](/src/collectors/COLLECTORS.md) for metrics you need, [configure the collector](/src/collectors/REFERENCE.md) or read about its requirements to configure your endpoint to publish metrics in the correct format and endpoint.

 Netdata comes with hundreds of pre-configured alerts, designed by our monitoring gurus in parallel with our open-source community, but you may want to [edit alerts](/src/health/REFERENCE.md) or [enable notifications](/docs/alerts-and-notifications/notifications/README.md) to customize your Netdata experience.

 By default, Netdata's installation scripts enable automatic updates for both nightly and stable release channels.

-Netdata](/packaging/installer/UPDATE.md).

-#### Network usage of Netdata’s automatic updater
-
-The auto-update functionality set up by the installation scripts requires working internet access to function
-correctly. In particular, it currently requires access to GitHub (to check if a newer version of the updater script
-is available or not, as well as potentially fetching build-time dependencies that are bundled as part of the install),
-and Google Cloud Storage (to check for newer versions of Netdata and download the sources if there is a newer version).
-
-Note that the auto-update functionality will check for updates to itself independently of updates to Netdata,
-and will try to use the latest version of the updater script whenever possible. This is intended to reduce the
-amount of effort required by users to get updates working again in the event of a bug in the updater code.
-
-### Nightly vs. stable releases
+With automatic updates disabled, you can choose exactly when and how you [update Netdata](/packaging/installer/UPDATE.md).
 
-The Netdata team maintains two releases of the Netdata agent: **nightly** and **stable**. By default, Netdata's
