 Using Infinite Maps
 ===================
 
-Infinite maps give you independence from bounds of the map. The canvas is
-"auto-growing", which basically means, that you have an infinite grid which
-can be painted upon without worrying about the width and height of the map.
-The bounds of a particular layer get expanded whenever tiles are painted
-outside the current bounds.
+Infinite maps in Tiled free you from the constraints of the fixed-size map. 
+With an "auto-growing" canvas, you can paint on an infinite grid without being 
+limited by width and height. This document guides you through creating, editing, 
+and converting infinite maps in Tiled.

 Creating an Infinite Map
 ------------------------
 
-In the order to create an infinite map, make sure the 'Infinite' option is
-selected in New Map dialog.
+1. Open the New Map dialog (*File -> New -> New Map*).
+2. Ensure the 'Infinite' option is selected.

+   :alt: Tiled's New Map dialog window is shown. For the option "Map Size," the Infinite radio button is selected rather than Fixed.
    :scale: 66
 
-The newly created map will then have an infinite canvas.
+The map you create will have an infinite canvas.
 
-Editing the Infinite Map
+Editing an Infinite Map
 ------------------------
 
-Except for the :ref:`bucket-fill-tool`, all tools works exactly in the
-same way as in the fixed-size maps. The Bucket Fill Tool fills the
-current bounds of that particular tile layer. These bounds get increased
-upon further painting of that tile layer.
+Most tools in Tiled work the same way for infinite maps as they do for fixed-size maps. 
+However, the :ref:`bucket-fill-tool` fills only the current bounds of a tile layer.
+As you paint, these bounds expand.

-Conversion from Infinite to Finite Map and Vice Versa
+Converting Between Infinite And Fixed-Size Maps
 -----------------------------------------------------
 
-In the map properties, you can toggle whether the map should be infinite
-or not. When converting from infinite to a finite map, the width and
-height of the final map are chosen on the basis of bounds of all the
-tile layers.
+You can toggle between infinite and fixed-size maps in the Map Properties window. 
+When converting an infinite map to a fixed-size map, Tiled determines the final map's 
+width and height based on the bounds of all tile layers.
