+Features
+========
+
+- no Flash, images or 1px divs
+- no dependency on an external JavaScript library
+- dimensions of both the picker and the slider areas can be adjusted arbitrarily
+- minimalistic (about 400 loc including comments)
+- support for a large scale of browsers (including mobile browsers)
+- understandable (no magic behind, code can be easily read and therefore adjusted)
+- styleable in CSS
+- position of the slider and the picker areas is not hardcoded and can be changed in CSS
+- HSV, RGB and HEX output/input

+
+Description
+===========
+
+FlexiColorPicker is based on HSV color model. The only two parts of the color picker are therefore
+the **slider** for selecting _hue_ value and the **picker** for selecting _saturation_ and _value_. Both
+the **slider** and **picker** are HTML elements (usually `<div>`'s) that serve as wrappers for SVG/VML gradient
+rectangles. The **slider** gradient rectangle represents the _hue_ value (gradient with 9 `stop-color`s). The
+two overlapping black and white gradient rectangles of the **picker** represent the _saturation_ and _value_ values.
+The top level elements (`<svg>` in case of SVG enabled browser and `<div>` in case of VML enabled browser) 
+that wrap each of the **slider** and **picker** gradient rectangles have set `width` and `height` to `100%` which
+means that the color picker components (slider and picker) adjust themselfs automatically to the dimensions of the **slider** and **picker**
+HTML elements.
+
+
+API
+===
+
+**`ColorPicker(colorPickerElement, function(hex, hsv, rgb) { /*do something when the color changes */ })`**
+
+This is the no-hassle form of creating the color picker. This is the recommended call.
+
+Example:
+
+        <div id="mycolorpicker" class="cp-default"></div>
+        <script>
+            ColorPicker(document.getElementById('mycolorpicker'), function(hex, hsv, rgb) {
+                document.body.style.backgroundColor = hex;
+            });
+        </script>
+
+
+**`ColorPicker.prototype.setHsv(hsv)`**
+
+Sets HSV value.
+
+Example:
+
+        var cp = ColorPicker(document.getElementById('mycolorpicker'), function() {});
+        cp.setHsv({ h: 180, s: .2, v: .7 });
+
+**`ColorPicker.prototype.setRgb(rgb)`**
+
+Sets RGB value.
+
+Example:
+
+        var cp = ColorPicker(document.getElementById('mycolorpicker'), function() {});
+        cp.setRgb({ r: 120, g: 205, b: 18 });
+
+
+**`ColorPicker.prototype.setHex(hex)`**
+
+Sets HEX value.
+
+Example:
+
+        var cp = ColorPicker(document.getElementById('mycolorpicker'), function() {});
+        cp.setHex('#AB12FE');
+
+
+**`ColorPicker.positionIndicators(sliderIndicator, pickerIndicator, sliderCoordinate, pickerCoordinate)`**
+
+Positions indicators in the slider and the picker. This is a helper function that is supposed to be called
+in the callback function passed as the fourth argument to the `ColorPicker` function. The only thing it does is
+setting the `top` and `left` CSS coordinate on the `sliderIndicator` and `pickerIndicator` HTML elements.
+If you use the no-hassle form (see above), you don't have to deal with this function at all.
+
+Example:
+
+                ColorPicker(
+                        document.getElementById('slider'), 
+                        document.getElementById('picker'), 
+
+                        function(hex, hsv, rgb, pickerCoordinate, sliderCoordinate) {
+        
+                            ColorPicker.positionIndicators(
+                                document.getElementById('slider-indicator'),
+                                document.getElementById('picker-indicator'),
+                                sliderCoordinate, pickerCoordinate
+                            );
+        
+                            document.body.style.backgroundColor = hex;
+                    });
+
+
+**`ColorPicker.fixIndicators(sliderIndicator, pickerIndicator)`**
+
+This helper function just sets the `pointer-events` CSS property to `'none'` on both the `sliderIndicator` and
+`pickerIndicator`. This is necessary otherwise any mouse event (click, mousedown, mousemove) triggered
+on the `sliderIndicator` or `pickerIndicator` HTML elements would be cought instead of bypassed to
+the slider and the picker area, hence preventing the color picker to catch these UI events in order to change
+color. As `pointer-events` CSS property is not supported in all browsers, this function might workaround
+this issue in the future. At this time, setting `pointer-events: none` in CSS on the slider and picker indicators
+is equivalent.
+
+Again, if you use the no-hassle form (see above), you don't have to deal with this function at all.
+
+
+Examples
+========
+
+The basic example demonstrates the minimalism of the FlexiColorPicker. More useful examples follow.
+
+Basic
+-----
+
+            <html>
+              <head>
+                <script type="text/javascript" src="colorpicker.js"></script>
+                <style type="text/css">
+                  #picker { width: 200px; height: 200px }
+                  #slider { width: 30px; height: 200px }
+                </style>
+              </head>
+              <body>
+
+                <div id="picker"></div>
+                <div id="slider"></div>
+
+                <script type="text/javascript">
+
+                  ColorPicker(
+
+                    document.getElementById('slider'),
+                    document.getElementById('picker'),
+
+                    function(hex, hsv, rgb) {
+                      console.log(hsv.h, hsv.s, hsv.v);         // [0-359], [0-1], [0-1]
+                      console.log(rgb.r, rgb.g, rgb.b);         // [0-255], [0-255], [0-255]
+                      document.body.style.backgroundColor = hex;        // #HEX
+                    });
+
+                </script>
+              </body>
+            </html>
+
+
+Note that you can set arbitrary dimensions, position, border and other CSS properties on the slider and picker 
+elements as you would do with any other HTML element on the page.
+
+
+Advanced
+--------
+
+This is an advanced example showing how to work with custom indicators.
+
+        <html>
+          <head>
+            <script type="text/javascript" src="../colorpicker.js"></script>
+            <style type="text/css">
+        
+                #picker-wrapper {
+                    width: 200px;
+                    height: 200px;
+                    position: relative;
+                }
+                #slider-wrapper {
+                    width: 30px;
+                    height: 200px;
+                    position: relative;
+                }
+                #picker-indicator {
+                    width: 3px;
+                    height: 3px;
+                    position: absolute;
+                    border: 1px solid white;
+                }
+                #slider-indicator {
+                    width: 100%;
+                    height: 10px;
+                    position: absolute;
+                    border: 1px solid black;
+                }
+            </style>
+          </head>
+          <body>
+        
+              <div id="picker-wrapper">
+                  <div id="picker"></div>
+                  <div id="picker-indicator"></div>
+              </div>
+              <div id="slider-wrapper">
+                  <div id="slider"></div>
+                  <div id="slider-indicator"></div>
+              </div>
+        
+              <script type="text/javascript">
+        
+                ColorPicker.fixIndicators(
+                        document.getElementById('slider-indicator'),
+                        document.getElementById('picker-indicator'));
+        
+                ColorPicker(
+                        document.getElementById('slider'), 
+                        document.getElementById('picker'), 
+
+                        function(hex, hsv, rgb, pickerCoordinate, sliderCoordinate) {
+        
+                            ColorPicker.positionIndicators(
+                                document.getElementById('slider-indicator'),
+                                document.getElementById('picker-indicator'),
+                                sliderCoordinate, pickerCoordinate
+                            );
+        
+                            document.body.style.backgroundColor = hex;
+                    });
+        
+              </script>
+          </body>
+        </html>
+
+
+
+Note how the indicators work. There is no built-in indicators in FlexiColorPicker, instead, the user
+has a freedom to set their own indicators as normal HTML elements styled in CSS (or use one of the ready-to-use themes packaged with FlexiColorPicker). 
+
+
+No hassle
+---------
+
+If you don't want to deal with any of the above mentioned details and you're just looking for a copy-paste
+(one function call-like) color picker, see this example.
+
+        <html>
+          <head>
+            <script type="text/javascript" src="../colorpicker.js"></script>
+            <link rel="stylesheet" type="text/css" href="../themes.css" />
+          </head>
+          <body>
+        
+            <div id="color-picker" class="cp-default"></div>
+        
+            <script type="text/javascript">
+        
+              ColorPicker(
+        
+                document.getElementById('color-picker'),
+        
+                function(hex, hsv, rgb) {
+                    console.log(hsv.h, hsv.s, hsv.v);         // [0-359], [0-1], [0-1]
+                    console.log(rgb.r, rgb.g, rgb.b);         // [0-255], [0-255], [0-255]
+                    document.body.style.backgroundColor = hex;        // #HEX
+                });
+        
+            </script>
+          </body>
+        </html>
+
+
+The ColorPicker function has recognized only two arguments which means that it builds the HTML needed for you
+and also fixes and positions indicators automatically.
