-# Default Dialog Icons
+## Dialog
 
-This directory contains the default dialog icons. These are pre-compiled into a single C file (`defaultDialogIcons.c`) which resides in the `ffenestri` directory. If these icons are ever updated, then there is a need to run: `go run build.go` in this directory. This will generate a new `defaultDialogIcons.c` file in the `ffenestri` directory.
+NOTE: Currently, this is a Mac only feature.
+
+Place any PNG file in this directory to be able to use them in message dialogs.
+The files should have names in the following format: `name[-(light|dark)][2x].png`
+
+Examples:
+
+* `mypic.png` - Standard definition icon with ID `mypic`
+* `mypic-light.png` - Standard definition icon with ID `mypic`, used when system theme is light
+* `mypic-dark.png` - Standard definition icon with ID `mypic`, used when system theme is dark
+* `mypic2x.png` - High definition icon with ID `mypic`
+* `mypic-light2x.png` - High definition icon with ID `mypic`, used when system theme is light
+* `mypic-dark2x.png` - High definition icon with ID `mypic`, used when system theme is dark
+
+### Order of preference

+Icons are selected with the following order of preference:
+
+For High Definition displays:
+* name-(theme)2x.png
+* name2x.png
+* name-(theme).png
+* name.png
