 Textures
 --------
 
-Normally textures have a resolution of 16x16, but they can be in the order of 2: 16, 32, 64, 128, etc.
+Textures are usually 16 by 16 pixels.
+They can be any resolution, but it is recommended that they are in the order of 2 (eg, 16, 32, 64, 128, etc),
+as other resolutions may not be supported correctly on older devices.
 
 Textures should be placed in textures/. Their name should match ``modname_itemname.png``.\\
 JPEGs are supported, but they do not support transparency and are generally bad quality at low resolutions.
