further update to lnd+btcd installation guide

the following guide is an updated install process from the following which needs some work updating still
https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md

It is specific to btcd, lnd, on testnet, running on an ubuntu 16.04 server host.

It does not address mainnet, or using bitcoind, or nuetrino.

INSTALL
=======

install golang
  sudo apt-get install golang-1.9-go
  mkdir go

set go paths
  nano .profile

add to the end
  export GOROOT=/usr/lib/go-1.9/
  export GOPATH=$HOME/go
  export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

logout, log back in

check variables with
  go env

install glide
  go get -u github.com/Masterminds/glide

install lnd
  git clone https://github.com/lightningnetwork/lnd $GOPATH/src/github.com/lightningnetwork/lnd
  cd $GOPATH/src/github.com/lightningnetwork/lnd
  glide install
  go install . ./cmd/...

run tests
  go install; go test -v -p 1 $(go list ./... | grep -v  '/vendor/')

install btcd
  git clone https://github.com/roasbeef/btcd $GOPATH/src/github.com/roasbeef/btcd
  cd $GOPATH/src/github.com/roasbeef/btcd
  glide install
  go install . ./cmd/...

setup a $HOME/.btcd/btcd.conf file from https://github.com/btcsuite/btcd/blob/master/sample-btcd.conf

simplest version might be
  [Application Options]
  datadir=~/.btcd/data
  testnet=1
  externalip=YOURIP      #replace with your IP address
  ;addpeer=KNOWNPEERIP   #add a known peer if you want
  rpcuser=REPLACEME
  rpcpass=REPLACEME
  txindex=1
  ; debuglevel=info

run btcd and sync (will take a long time)
  btcd --testnet --txindex --rpcuser=REPLACEME --rpcpass=REPLACEME

monitor progress in another terminal window with
  btcctl --testnet --rpcuser=REPLACEME --rpcpass=REPLACEME getinfo
  btcctl --testnet --rpcuser=REPLACEME --rpcpass=REPLACEME getpeerinfo | more

to run in the background (and tail log file)
  btcd --testnet --txindex --rpcuser=REPLACEME --rpcpass=REPLACEME >> btcd.log  2>&1 &

view logs by going
  tail btcd.log

[Please see EXTRA section at end, for supervisor configuration to run btcd automatically]

create $HOME/.lnd/lnd.conf

  [Application Options]
  debuglevel=debug
  debughtlc=true
  maxpendingchannels=10
  noencryptwallet=true
  externalip=YOURIP

  [Bitcoin]
  bitcoin.active=1
  bitcoin.testnet=1

  [Btcd]
  btcd.rpcuser=<btcd rpc username>
  btcd.rpcpass=<btcd rpc password>

  [Neutrino]
  # neutrino.active=1
  neutrino.connect=faucet.lightning.community

  [Autopilot]
  # autopilot.active=1

Once btcd has synced, run lnd using the btcd backend and lnd.conf config file create
  lnd --bitcoin.active --bitcoin.testnet

to run in the background (and tail log file)
  lnd --bitcoin.active --bitcoin.testnet >> lnd.log 2>&1 &

tail the log file
  tail lnd.log

[Please see EXTRA section at end, for supervisor configuration to run automatically]

To verify things are operational
  lncli getinfo
  lncli getnetworkinfo
  lncli describegraph

Setup a wallet to get testnet coins from faucet (needs a np2wkh segwit format address)
  lncli newaddress np2wkh

open https://testnet.manu.backend.hamburg/faucet and paste in the address you created and click 'give me some coins' multiple times

After a few minutes your coins should have arrived. You can verify with
  lncli walletbalance

Open a channel to one or more of the following, or another peer you know

Open a channel by first connection, then opening a channel as follows
  lncli connect pubkey@ip:port
  lncli openchannel --node_key=<pubkey> --local_amt=100000

verify pending & open channels using
  lncli pendingchannels
  lncli listchannels

EXTRA
=====
start btcd and lnd automatically using supervisor. First install supervisor
  sudo apt-get install supervisor

Then add two configuration files as follows:
  cd /etc/supervisor/conf.d

  nano btcd.conf

  [program:btcd]
  user=REPLACE-WITH-YOUR-USERNAME
  command=/home/YOUR-HOME-DIR/go/bin/btcd --testnet --txindex --rpcuser=REPLACEME --rpcpass=REPLACEME
  stdout_logfile = /home/YOUR-HOME-DIR/btcd.log
  stderr_logfile = /home/YOUR-HOME-DIR/btcd.log
  startretries=999999999999999999999999999
  autostart = true
  autorestart=true

  nano lnd.conf

  [program:lnd]
  user=REPLACE-WITH-YOUR-USERNAME
  command=/home/YOUR-HOME-DIR/go/bin/lnd --bitcoin.active --bitcoin.testnet
  stdout_logfile = /home/YOUR-HOME-DIR/lnd.log
  stderr_logfile = /home/YOUR-HOME-DIR/lnd.log
  startretries=999999999999999999999999999
  autostart = true
  autorestart=true

and start the processes
  sudo supervisorctl start btcd
  sudo supervisorctl start lnd

monitor the log files by tailing them
