+nvOC MiningPoolHub Switcher
+===========================
+
+nvOC makes it easy to squeeze more hashrate out of your GPUs.  MiningPoolHub
+makes it easy to mine altcoins and get paid in Bitcoin.  However, nvOC is a
+customized Ubuntu Linux and the management software MiningPoolHub recommends
+for profit switching only runs under Windows.  Their approach to
+coin-switching with nVidia GPUs under Linux is to loop through a bunch of
+different miners, erroring out on all but the currently-profitable coin.  I
+lost nearly four hours this morning when a miner didn't exit properly during
+a switch.
+
+This set of scripts bridges the gap.  With them, you can use the miners
+included in nvOC (and others that you might add) to mine whatever's most
+profitable at MiningPoolHub.  For each supported algorithm, you can
+customize power, clockspeed, and fan speed settings as you consider
+appropriate.  
+
+Setup
+-----
+
+1. ssh into your mining rig's m1 account.
+2. Clone these files into the same directory as nvOC's oneBash script.
+3. Disable oneBash by commenting out all lines in ~/2unix.  oneBash should
+be invoked manually if you add/remove GPUs so it can reconfigure
+/etc/X11/xorg.conf, but it otherwise isn't used.  To keep gnome-terminal
+from sucking down CPU cycles by constantly restarting the 2unix script, you
+might want to include something like "sleep 86400" at the end.
+4. Edit mph_conf.json.  You'll set your user and miner names here.  You can 
+also customize your overclocking settings for each algorithm here.
+5. If your network is IPv6-enabled, note that nvOC (as of v17) has a problem
+connecting to IPv6 hosts.  MiningPoolHub makes its API available over both IPv6
+and IPv4, so to force it to use IPv4 in the meantime, edit /etc/hosts as
+follows:
+
+    `104.27.168.52 miningpoolhub.com`
+6. Set mph_switch.py to launch with a cronjob:
+
+    `0,10,20,30,40,50 * * * * (cd /media/m1/1263-A96E && python2.7 mph_switch.py mph_conf.json)`
+
+Every 10 minutes, the script will run and determine which miner needs to
+start up.  If it's already running, it will leave it alone.  If it needs to
+switch, it kills one miner and starts the other.  If nothing's running
+(because the rig just rebooted or the miner crashed), it will start the
+miner.
+
+current-profit is a text file that will be updated on every run of switch.py
+to show which is currently the most profitable.  Profitability is determined
+by the MiningPoolHub API and is a unitless number; higher is better.
+
+algo-log is a list of coins and algorithms the switcher has selected when
+run.  If you start seeing repeats of the same algo every 10 minutes, that's
+a sign that something has gone wrong with your GPUs and you might want to
+consider a reboot.
+
+Miners are started in Screen sessions (http://www.gnu.org/software/screen)
+that can be viewed over an ssh login session:
+
+`screen -dr miner`
+
+When the rig switches algorithms, the Screen session will be closed and a
+new one opened.  Repeat the above to monitor it, or you could use something
+like this on a monitoring workstation:
+
+`while true; do screen -dr miner; done`
+
+Adding Algorithms
+-----------------
+
+Some algorithms supported by MiningPoolHub can't be mined with the miners
+included in nvOC.  If you add the appropriate software, though, you can mine
+these as well.  Instructions to add these capabilities will follow.
+
+Sia
+---
+
+To add the miner:
+
+`sudo apt install golang-go
+mkdir /home/m1/gocode
+GOPATH=/home/m1/gocode go get github.com/robvanmieghem/gominer`
+
+To enable mining, create a new object named "sia" within the "miners"
+list in mph_conf.json.  Here's what I use:
+
+```
+ "miners": 
+ {
+   [existing entries deleted for brevity]
+    "Sia":
+    {
+      "bin": "/home/m1/SPccminer/ccminer -a sia -o stratum+tcp://{HOST}:{PORT} -u {NAME}.{MINER} -p x",
+      "power_limit": [115,115,95], "gpu_oc": [-100,-100,0], "mem_oc": 0, "fan": [70,75,70]
+    }
+ }
+```
+
+CryptoNight
+-----------
+
+To add the miner:
+
+`cd /home/m1
+git clone https://github.com/KlausT/ccminer-cryptonight KTccminer-cryptonight
+cd KTccminer-cryptonight
+./autoreconf.sh
+./configure --with-cuda-/usr/local/cuda-8.0
+make`
+
+To enable mining, create a new object named "cryptonight" within the "miners"
+list in mph_conf.json.  Here's what I use:
+
+```
+ "miners": 
+ {
+   [existing entries deleted for brevity]
+    "Cryptonight":
+    {
+      "bin": "/home/m1/KTccminer-cryptonight/ccminer -a cryptonight -o stratum+tcp://{HOST}:{PORT} -u {NAME}.{MINER} -p x",
+      "power_limit": [115,115,95], "gpu_oc": -200, "mem_oc": 1000, "fan": [70,75,70]
+    }
+ }
+```
