-
-  Fast Swift UIViews layouting without auto layout. No magic, pure code, full control and blazing fast. Concise syntax, intuitive, readable & chainable.
-  Support left to right (LTR) and right to left (RTL) languages.
+  
+* Layout one view at a time. 
+* Layout most views using a single line
+* Stateless
+  * The layout system doesn’t add any stored properties to UIViews. It simply compute the UIView.frame property, one view at a time.
+  * Since it is stateless, it can be used with any other layout framework without conflicts. 
+Each view can use the layout system that better suit it  (PinLayout, constraint, flexbox, grids, …)
+A view can be layouted using PinLayout and later with another method.
+  * REWORK THAT!!! Stateless also means that if a view reference other views, the view should be re-layouted in layoutSubViews()  layouted with PinLayout use other views as referenced view change (size/position) 
+
+* No constraints
+  * Constraints are very verbose and hard for a human brains to understand. Too much information.
+  * PinLayout positions views as a designer would explain it (eg: “The TextField is below the Label, aligned left, and is its width match the other view’s width“). 
+  * No priorities, simply layout views in the order that make sense. No priority required.
+
+* Before applying the new sets of attributes, PinLayout always start with the view’s current frame. So it’s possible to set the view’s size during the initialization (ex: view.pin.width(100).height(200)), and later only position the view (ex: view.pin.top(10).left(20))
+
+* Minimize as much as possible calculations and constants when layouting views.
+
+* Methods matches as much as possible other layouting system, including CSS, flexbox, reactive Flexbox, …
+  * margin, marginHorizontal, marginVertical, marginTop, marginLeft, marginBottom, marginRight
+  * top, left, bottom, right, width, height  
+  * As in CSS and flexbox, right and bottom coordinates are offset from container’s view right and bottom edges.
+
+* Shorter possible commands to layout views, but keeping english phrasing almost valid.
