 Application icons
 =================
 
- * The reference icon is the SVG at hicolor/scalable/apps/meld.svg. It is
-   designed on a 48x48 canvas, but given the nature of the Meld icon's design,
-   scales fairly well to higher resolutions.
- * The 48x48 icon is exported from the reference SVG.
- * The 32x32 icon is exported from an old SVG; the new one could be used but
-   requires some simplification and border trimming.
- * The 16x16 and 22x22 icons are exported from old XCF files. They should be
-   updated based on the reference SVG.
+ * The reference icon is the SVG at hicolor/scalable/apps/org.gnome.meld.svg.
+   It is designed on a 128x128 canvas and scales fairly well to higher
+   resolutions.
