-# Invite your team and collaborate
-
-Netdata is designed to make an infrastructure's real-time metrics available and actionable to all organization members.
-By inviting others, you can better synchronize with your team or colleagues to understand your infrastructure's
-heartbeat. When something goes wrong, you'll be ready to collaboratively troubleshoot complex performance problems from
-a single pane of glass.
-
-## Invite new members
-
-Invite new users by clicking on your Space's name in the top navigation, and then **Invite more users**, to open the
-invitation pane. Admins manage user permissions and have control over who can access specific Spaces and War Rooms.

-invitations and moves them to the **Invitations awaiting response** category.
-
-Your team will receive their email invitations momentarily with a prompt to sign in to join your Space.
-
-## Collaboration with Netdata Cloud
-
-Netdata Cloud gives teams a single interface to view real-time metrics across their entire infrastructure. Having all
-the metrics, alarm statuses, dashboards, and people in one place is a powerful asset for any infrastructure monitoring
-team.
-
-Assets like dashboards and bookmarks are shared between members of a War Room. As soon as one member creates a
-dashboard, for example, other members of the same War Room can see it in the War Room's dropdown and supplement it with
-additional charts/text.
-
-Let's say you get an alert from your nodes about an excess of 500-type errors in your Nginx logs. Your team can hop on a
-Slack call to begin working together. While one engineer handles creating a new dashboard with a half-dozen relevant
-Nginx log metrics, another can dive into the real-time node dashboard and investigate correlated charts in granular
-detail.

-# Set up Spaces and War Rooms
-
-Spaces and War Rooms help you organize your real-time infrastructure monitoring experience in Netdata Cloud. You already
-created a Space and War Room when you first signed in to Cloud, assuming you weren't invited to an existing Space by
-someone else.
-
-In either case, you can always create new Spaces and War Rooms based on your changing needs or a scaled-up
-infrastructure. Let's talk through some strategies for building the most intuitive Cloud experience for your team.
-
-> This guide assumes you've already [signed in](https://app.netdata.cloud) to Netdata Cloud and finished creating your
-> account. If you're not interested in Netdata Cloud's features, you can skip ahead to [node configuration
-> basics](/docs/configure/nodes.md).
-
-## Spaces
-
-Spaces are high-level containers to help you organize your team members and the nodes they can view in each War Room.
-You already have at least one Space in your Netdata Cloud account.
-
-To create a new Space, click the **+** icon, enter its name, and click **Save**. Netdata Cloud distinguishes between
-Spaces with abbreviated versions of their name. Click on any of the icons to switch between them.
-
-![Spaces navigation in Netdata
-Cloud](https://user-images.githubusercontent.com/1153921/92177439-5b22d000-edf5-11ea-9323-383347f21c8d.png)
-
-The organization you choose will likely be based on two factors:
-
-1.  The fact that any node can be claimed to a single Space.
-2.  The size of your team and the complexity of the infrastructure you monitor.
-
-A single Space puts all your metrics in one easily-accessible place, while multiple Spaces creates logical division
-between different users and different pieces of a large infrastructure.
-
-For example, a large organization might have one SRE team for the user-facing SaaS application, and a second IT team for
-managing employees' hardware. Since these teams don't monitor the same nodes, they can work in separate Spaces and then
-further organize their nodes into War Rooms.
-
-You can also use multiple Spaces for different aspects of your monitoring "life," such as your work infrastructure
-versus your homelab.
-
-## War Rooms
-
-War Rooms are granular containers for organizing nodes, viewing key metrics in real-time, and monitoring the health and
-alarm status of many nodes. 
-
-War Rooms organize the [at-a-glance Node view](/docs/visualize/view-all-nodes.md) and any [new
-dashboards](/docs/visualize/create-dashboards.md) you build.
-
-We recommend a few strategies for organizing your War Rooms.
-
-**Service, purpose, location, etc.**: You can group War Rooms by a service (think Nginx, MySQL, Pulsar, and so on),
-their purpose (webserver, database, application), their physical location, whether they're baremetal or a Docker
-container, the PaaS/cloud provider it runs on, and much more. This allows you to see entire slices of your
-infrastructure by moving from one War Room to another.
-
-**End-to-end apps/services**: If you have a user-facing SaaS product, or an internal service that said product relies
-on, you may want to monitor that entire stack in a single War Room. This might include Kubernetes clusters, Docker
-containers, proxies, databases, web servers, brokers, and more. End-to-end War Rooms are valuable tools for ensuring the
-health and performance of your organization's essential services.
-
-**Incident response**: You can also create new War Rooms as one of the first steps in your incident response process.
-For example, you have a user-facing web app that relies on Apache Pulsar for a message queue, and one of your nodes
-using the [Pulsar collector](https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/pulsar) begins
-reporting a suspiciously low messages rate. You can create a War Room called `$year-$month-$day-pulsar-rate`, add all
-your Pulsar nodes in addition to nodes they connect to, and begin diagnosing the root cause in a War Room optimized for
-getting to resolution as fast as possible.
-
-For example, here is a War Room based on the node's provider and physical location (**us-east-1**).
-
-![An example War Room based on provider and
-location](https://user-images.githubusercontent.com/1153921/92178714-ff0d7b00-edf7-11ea-8411-09b2e75a5529.png)

-## What's next?

 # Infrastructure monitoring with Netdata
 
-Together, the Netdata Agent and Netdata Cloud create a powerful, infinitely-scalable infrastructure monitoring solution.
+[Netdata Cloud](https://app.netdata.cloud) provides scalable infrastructure monitoring for any number of distributed
+nodes running the Netdata Agent. A node is any system in your infrastructure that you want to monitor, whether it's a
+physical or virtual machine (VM), container, cloud deployment, or edge/IoT device.
 
 The Netdata Agent uses zero-configuration collectors to gather metrics from every application and container instantly,
 and uses Netdata's [distributed data architecture](/docs/store/distributed-data-architecture.md) to store metrics
 locally. Without a slow and troublesome centralized data lake for your infrastructure's metrics, you reduce the
 resources you need to invest in, and the complexity of, monitoring your infrastructure. 
 
-Netdata Cloud unifies monitoring your infrastructure by _centralizing the interface_ you use to query and visualize your
+Netdata Cloud unifies infrastructure monitoring by _centralizing the interface_ you use to query and visualize your
 nodes' metrics, not the data. By streaming metrics values to your browser, with Netdata Cloud acting as the secure proxy
 between them, you can monitor your infrastructure using customizable, interactive, and real-time visualizations from any
 numbe of distributed nodes.
 
-In this quickstart guide, you'll learn how to see key metrics from all your nodes in one interface and build your first
-dashboard for aggregating like metrics from many distributed nodes. You'll then take a peek into configuring individual
-nodes and get helpful pointers about collecting all the metrics from every critical application in your infrastructure.

 You can use single-node dashboards in Netdata Cloud to drill down on specific issues, scrub backward in time to
 investigate historical data, and see like metrics presented meaningfully to help you troubleshoot performance problems.
 All of the familiar [interactions](/docs/visualize/interact-dashboards-charts.md) are available, as is adding any chart
 to a [new dashboard](/docs/visualize/create-dashboards.md).
 
-Using the above example, one of the single-node dashboards reveals similar spike in disk I/O. Interestingly enough, it
-also shows a maximum disk write of 31 MiB/s at the exact same moment as the composite chart in Overview.

-You now know that this particular node, during this particular time, experienced anomalous behavior. In this case, the
-root cause of the disk I/O spike was due to updating the Netdata Agent itself, which is also the cause of the subsequent
-gap in metrics history.
