I have just updated my electrum wallet today on my mobile phone to the latest version (4.0.2), I was surprised to see "lightning", I assumed it to be lightning network. I do not really know about it. I saw:

Gossip: Not connected
Connections with lightning nodes

Nodes: 0
Nodes in database

Channels: 0
Channels in database

Pending: 0
Channel updates to query

I practically do not know how to use the lightning network. I will like your help.
