+### Remarks
+
+Items in a RelativeCanvas are placed relative to the RelativeCanvas itself. The following attached properties each have their use:
+
+* RelativeCanvas.Left (value >= 0): used to indicate where to place the item from left to right.
+  * 0 = Extreme left
+  * 1 = Extreme right
+* RelativeCanvas.Top (value >= 0): used to indicate where to place the item from top to bottom.
+  * 0 = Complete top
+  * 1 = Complete bottom
+* RelativeCanvas.RelativeWidth (value >= 0): used to indicate the width of the element relative to the width of the RelativeCanvas
+  * ex: a value of 0.5 will indicate that the element's width must be half the width of the RelativeCanvas
+* RelativeCanvas.RelativeHeight (value >= 0): used to indicate the height of the element relative to the height of the RelativeCanvas
+  * ex: a value of 0.5 will indicate that the element's height must be half the height of the RelativeCanvas
+* RelativeCanvas.PinPoint: reference point from which the other properties/characteristics will be calculated.
+  * (0,0) = Top left corner
+  * (1,0) = Top right corner
+  * (0,1) = Bottom left corner
+  * (1,1) = Bottom right corner
+
+This means that the attached properties RelativeCanvas.RelativeWidth and RelativeCanvas.RelativeHeight must be set on the elements that should have a size relative to the size of the RelativeCanvas.
+
+For elements that should have a fixed size, assign a value to FrameworkElement.Width and/or FrameworkElement.Height. For elements that should have a size in function of their content, do not specify anything.
