 # Registry
 
-Netdata registry implements the `my-netdata` menu on netdata dashboards.
-The `my-netdata` menu lists the netdata servers you have visited.
+The Netdata registry implements the node menu on the top left corner of the netdata dashboards and enables the Netdata cloud features, such as the node view.
+The node menu lists the netdata servers you have visited. The node view offers a lot of additional features on top of the menu, 
+[with many more to come](https://blog.netdata.cloud/posts/netdata-cloud-announcement/). 
+To enable the global Netdata registry and the cloud features, you need to Sign In to Netdata cloud. By signing in, you opt in to let the registry receive and store 
+the information described [here](#what-data-does-the-registry-store). 
+You can still get the node menu, but not the cloud features, if you [run your own registry](#run-your-own-registry).

 However, the netdata approach introduces a few new issues that need to be addressed, one being **the list of netdata we have installed**, i.e. the URLs our netdata servers are listening.
 
-To solve this, netdata utilizes a **central registry**. This registry, together with certain browser features, allow netdata to provide unified cross-server dashboards. For example, when you jump from server to server using the `my-netdata` menu, several session settings (like the currently viewed charts, the current zoom and pan operations on the charts, etc.) are propagated to the new server, so that the new dashboard will come with exactly the same view.

   For each URL, the registry keeps the URL and nothing more. Each URL is linked to *persons* and *machines*. The only way to find a URL is to know its **machine_guid** or have a **person_guid** it is linked to it.
 
+4. **accounts**: i.e. the information used to sign-in via one of the available sign-in methods. Depending on the method, this may include an email, an email and a profile picture.

-Its database contains:
-
-- **random person GUIDs** (generated by the registry as a browser cookie)
-- **random machine GUIDs** (generated by each netdata server on its first run), including the hostname of the server netdata is running (without the domain)

 ## Which is the default registry?
 
 `https://registry.my-netdata.io`, which is currently served by `https://london.my-netdata.io`. This registry listens to both HTTP and HTTPS requests but the default is HTTPS.
