@@ -8,8 +8,36 @@ Functional userspace driver for Brother scanners.
 This is a server for brother click-to-scan feature.
 To scan, simply press a button on the scanner.
 
+This is a cross-platform, open-source and headless equivalent of Brother's Control Center 4.
+
 Written in C11. Does not use any external dependencies.
 
+## Advantages over the official Linux driver
+
+Brother released a Linux driver for their scanners, however... 
+
+The official Linux driver uses click-to-scan Brother protocol only to notify about the button press event.
+After receiving such event, the driver closes the connection and starts up separate SANE application
+that will establish connection with the same scanner (again!) and will request single page scan.
+
+As for DCP-J105 scanner model, the connection establishment + handshake takes around 3 seconds.
+To scan a single page, one would have to wait at least 6 seconds before the actual scanning starts.
+
+The press-to-scan protocol offers much more than. It can be used to receive entire
+image data within the same (original) connection. But only on Windows... Well, not anymore!
+
