Bitcoin Core SegWit Testnet Full Node

[miguelmorales85]

I would like to know how to set a BitcoinCore SegWit full node.
I want to support this testnet.

I can see from here https://bitcoincore.org/en/2016/01/21/launch_segwit_testnet/

Testing

Finally and most importantly, please help test the Segwit Testnet!

The source-code can be located here checkout the segwit branch.

Once compiled, add -segnet to the standard bitcoind and bitcoin-cli command line.

But I would need clearer instructions

Pull the source code from https://github.com/sipa/bitcoin/tree/segwit2. Build it, then run. I think you will need to run it in testnet mode.
