+## Embedded + `chrome.sockets`
+
+This node type replaces regular _Embedded_ type if browser vendor granted us access to `chrome.sockets` APIs.  
+Those powerful APIs enable exciting possibilities:
+
+- Embedded HTTP Gateway [wip]
+- True P2P over TCP/UDP transports [future]
+- Local Discovery (mDNS/DNS-SD) [future]
+
+**Note:** this is still work in progress: one can track progress in [ipfs-companion/issues/664](https://github.com/ipfs-shipyard/ipfs-companion/issues/664).  
+Right now only [Brave Nightly](https://brave.com/download-nightly/) supports this.

 ## Public
 
 Public node is not a part of the toggle UI. It is used as an implicit fallback for its Gateway functionality when External node is offline or Embedded node is used.
 It does not expose API port.
