 Configuration:
 --------------
 
-Configuration needs to be done before compiling. There are some parameters you can set in the head of the spacetray.c file where variables are declared. A configuration file will at this point make no sense.
+Configuration is done via command line arguments.
 
 Usage:
 ------
 
 Run spacetray with:
 
-    ./spacetray &
+    ./bin/spacetray <statusurl> &
 
 Or if in your $PATH:
 
-    spacetray
+    spacetray <statusurl>

 Themes:
 -------
 
-You can create your own icon theme by generating a C header file containing the icons as "static const GdkPixdata" data structure.
+You can create your own icon theme by generating a C++ header file containing the icons as raw RGBA8888 pixel data in a `static const quint8` array.
 
-This can be done using the following commands:
+The format should look like this:
 
-    gdk-pixbuf-csource --struct PATH_TO_OPEN_IMAGE > ./themes/THEME_NAME.h
+    static const quint8 icon_open_data[] = {
+      0xRR, 0xGG, 0xBB, 0xAA, ...
+    };
 
-    gdk-pixbuf-csource --struct PATH_TO_CLOSED_IMAGE >> ./themes/THEME_NAME.h
+    static const quint8 icon_closed_data[] = {
+      0xRR, 0xGG, 0xBB, 0xAA, ...
+    };
 
-Afterwards you need to rename the first generated struct to:
+The image size used in the default theme is 52x48 pixels with 4 channels (RGBA).
 
-    icon_open_pixbuf
+To create these arrays from a PNG image, you can use `ImageMagick` to convert the image to raw RGBA data and then format it into a C++ header.
 
-The second must be renamed to:
+Example using `magick` (ImageMagick 7):
 
-    icon_closed_pixbuf
+    magick icon_open.png -size 52x48 -depth 8 RGBA:icon_open.raw
+    hexdump -v -e '12/1 "0x%02x, " "\n"' icon_open.raw
 
-in:
+Or using a simple one-liner to generate the header content:
 
-    ./themes/THEME_NAME.h
+    echo "static const quint8 icon_open_data[] = {" > themes/my_theme.h
+    magick icon_open.png -size 52x48 -depth 8 RGBA:- | hexdump -v -e '12/1 "0x%02x, " "\n"' >> themes/my_theme.h
+    echo "};" >> themes/my_theme.h
 
-You can then use your custom icon theme when changing the line:
+Repeat the process for `icon_closed_data` and append it to the same header file.
