 # 2.8. Code Attributes
 
-Code attributes instruct the Vala compiler details about how the code is
-supposed to work on the target platform. Their syntax is
-`[AttributeName]` or
-`[AttributeName(param1 = value1, param2 = value2, ...)]`.
-
-They are mostly used for bindings in *vapi* files, `[CCode(...)]` being
-the most prominent attribute here. Another example is the `[DBus(...)]`
-attribute for exporting remote interfaces via
-[D-Bus](http://www.freedesktop.org/wiki/Software/dbus).
+Code attributes instruct the Vala compiler details about how the code is supposed to work on the target platform. 
+They are mostly used for bindings in *vapi* files.
+
+The most prominent example is the `[CCode (...)]` attribute:
+
+```vala
+[CCode (cname = "SDL_PropertiesID", has_type_id = false)]
+public struct PropertiesID : uint32 {}
+```
+
+Another common example is the `[DBus (...)]` attribute, which is used for exporting remote interfaces via 
+[D-Bus](http://www.freedesktop.org/wiki/Software/dbus):
+
+```vala
+[DBus (name = "net.example")]
+public interface Header.Example {
+    // ...
+}
+```
+
+Here are some examples of the syntax:
+
+```vala
+[AttributeName]
+class Example {
+    // ...
+}
+
+[AttributeName, AnotherAttributeName]
+var number = 1;
+
+[AttributeName, AnotherAttributeName (name = "value"), YetAnotherAttributeName]
+var str = "string";
+
+[AttributeName (name = "value"), AnotherAttributeName]
+var character = 'c';
+
+[AttributeName]
+[AttributeName (name = "value")]
+var boolean = true;
+
+[AttributeName (name = "value", anotherName = 1, thirdName = false)]
+int integer = 1;
+```
+
+You can use as many attributes and arguments in the attributes as you want.
