+== Installation
+
+Install vICN from either a debian package or by cloning the git repositoy.
+
+Add the image server certificate to your trusted certificates:
+
+    sudo apt-get install ca-certificates
+    wget https://46.105.122.213/cicn.crt
+    sudo cp cicn.crt /usr/share/ca-certificates
+    sudo dpkg-reconfigure ca-certificates
+
+    # This should be done by the LXD remote add
+    cp /usr/share/ca-certificates/cicn.crt ~/.config/lxc/servercerts/
+
+    lxc remote add cicn https://46.105.122.213  --protocol=simplestreams
+
+You can now list image with:
+
+    lxc image list cicn:
+
+or run containers:
+
+    lxc launch cicn:cicn/1.0 test
+
 == Getting started

+/* Plugin for jQuery for working with colors.
+ *
+ * Version 1.1.
+ *
+ * Inspiration from jQuery color animation plugin by John Resig.
+ *
+ * Released under the MIT license by Ole Laursen, October 2009.
+ *
+ * Examples:
+ *
+ *   $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
+ *   var c = $.color.extract($("#mydiv"), 'background-color');
+ *   console.log(c.r, c.g, c.b, c.a);
+ *   $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
+ *
+ * Note that .scale() and .add() return the same modified object
+ * instead of making a new one.
+ *
+ * V. 1.1: Fix error handling so e.g. parsing an empty string does
+ * produce a color rather than just crashing.

+/* Flot plugin for thresholding data.
+
+Copyright (c) 2007-2014 IOLA and Ole Laursen.
+Licensed under the MIT license.
+
+The plugin supports these options:
+
+	series: {
+		threshold: {
+			below: number
+			color: colorspec
+		}
+	}
+
+It can also be applied to a single series, like this:
+
+	$.plot( $("#placeholder"), [{
+		data: [ ... ],
+		threshold: { ... }
+	}])
+
+An array can be passed for multiple thresholding, like this:
+
+	threshold: [{
+		below: number1
+		color: color1
+	},{
+		below: number2
+		color: color2
+	}]
+
+These multiple threshold objects can be passed in any order since they are
+sorted by the processing function.
+
+The data points below "below" are drawn with the specified color. This makes
+it easy to mark points below 0, e.g. for budget data.
+
+Internally, the plugin works by splitting the data into two series, above and
+below the threshold. The extra series below the threshold will have its label
+cleared and the special "originSeries" attribute set to the original series.
+You may need to check for this in hover events.
