This is a description of how to get started with Signet. This document assumes you are capable of using git, and that you are able to compile Bitcoin. (If you have not yet done so, you should begin by doing that now.)
$ git clone https://github.com/kallewoof/bitcoin.git signet
$ cd signet
$ git checkout signet-0.18
$ ./autogen.sh
$ ./configure
$ make -j5
cd src
mkdir signet
echo "signet=1
daemon=1" > signet/bitcoin.conf
./bitcoind -datadir=signet
./bitcoin-cli -datadir=signet getconnectioncount
***SHOULD BE MORE THAN ZERO***
./bitcoin-cli -datadir=signet getblockcount
***SHOULD BE MORE THAN ZERO***
You first need an address
./bitcoin-cli -datadir=signet getnewaddress
Then just DM @kallewoof on Twitter or on IRC with "Signet coins plz: PASTEADDRESSHERE" and I'll try to send you some asap. (It's manual tho so may take awhile if I'm not near a computer.)
