 ### Section `source`:
 
 - `type`: this field must be set to the literal value `N2N`
-- `address`: a tuple describing the location of the tcp endpoint It must be specified as a string with hostname and port number.
-- `magic`: the magic of the network that the node is running (`mainnet`, `testnet` or a custom numeric value)
-- ~~`since`~~: (deprecated, please use `intersect`) the point in the chain where reading of events should start from. It must be specified as a tuple of slot (integer) and block hash (hex string)
-
-### Section `source.intersect`
-
-This section provides advanced options for instructing Oura from which point in the chain to start reading from. Read the [intersect options](../advanced/intersect_options.md) documentation for detailed information.
-
-### Section `source.mapper`
-
-This section provides a way to opt-in into advances behaviour of how the raw chain data is mapped into _Oura_ events. Read the [mapper options](../advanced/mapper_options.md) documentation for detailed information.
+- `peers`: the location of the tcp endpoint It must be specified as a string with hostname and port number.
 
 ## Examples
 
-Connecting to a remote Cardano node in mainnet through tcp sockets:
-
-```toml
-[source]
-type = "N2N"
-address = ["Tcp", "relays-new.cardano-mainnet.iohk.io:3001"]
-magic = "mainnet"
-```

-Connecting to a remote Cardano node in testnet through tcp sockets:
