+To build Ethereal (GUI):
 
-Command line options
+`go get github.com/ethereum/go-ethereum/ethereal`
+
+To build the node (CLI):
+
+`go get github.com/ethereum/go-ethereum/ethereum`
+
+For further, detailed, build instruction please see the [Wiki](https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum(Go))
+
+General command line options
