+### Multiple suppressions
+
+For a line of code there might be several warnings you want to suppress.
+
+There are several options;
+
+Using 2 suppression comments before code:

+    void f() {
+        char arr[5];
+
+        // cppcheck-suppress arrayIndexOutOfBounds
+        // cppcheck-suppress zerodiv

+Using 1 suppression comment before the code:
+
+    void f() {
+        char arr[5];
+
+        // cppcheck-suppress[arrayIndexOutOfBounds,zerodiv]
+        arr[10] = arr[10] / 0;

+Suppression comment on the same line as the code:
+
+    void f() {
+        char arr[5];
+
+        arr[10] = arr[10] / 0;  // cppcheck-suppress[arrayIndexOutOfBounds,zerodiv]
+    }
+
+
+### Symbol name
 
 You can specify that the inline suppression only applies to a specific symbol:
 
-    // cppcheck-suppress arrayIndexOutOfBounds symbolName=arr
+    // cppcheck-suppress aaaa symbolName=arr
 
-You can write comments for the suppress, however is recommended to use ; or // to specify where they start:
+Or
 
-    // cppcheck-suppress arrayIndexOutOfBounds ; some comment
-    // cppcheck-suppress arrayIndexOutOfBounds // some comment
+    // cppcheck-suppress[aaaa symbolName=arr, bbbb]
+
+### Comment about suppression
+
+You can write comments about a suppression like so:
+
+    // cppcheck-suppress[warningid] some comment
+    // cppcheck-suppress warningid ; some comment
+    // cppcheck-suppress warningid // some comment
