       <title>CTH Execution Order</title>
       <p>By default, each CTH installed is executed in the order that
-      they are installed for init calls, and then reversed for end calls.
-      This is not always desired, so <c>Common Test</c> allows
-      the user to specify a priority for each hook. The priority can either
-      be specified in the CTH function 
-      <seemfa marker="ct_hooks#Module:init/2">init/2</seemfa> or when 
-      installing the hook. The priority specified at installation overrides the 
-      priority returned by the CTH.</p>
+      they are installed for init calls, and then reversed for end
+      calls. This order can be referred as test centric, as order is
+      reversed after testcase is executed and corresponds to default
+      value <c>test</c> of <c>ct_hooks_order</c> option.</p>
+      <p>Installation based order is not always
+      desired, so <c>Common Test</c> allows the user to specify a
+      priority for each hook. The priority can either be specified in
+      the CTH function <seemfa
+      marker="ct_hooks#Module:init/2">init/2</seemfa> or when
+      installing the hook. The priority specified at installation
+      overrides the priority returned by the CTH.</p>
+      <p>In some cases, reversed order for all end calls is not
+      desired and instead user might prefer reversed order for post
+      hook calls. Such behavior can be enabled with
+      <c>ct_hooks_order</c> option with <c>config</c> value. When
+      option is enabled, execution order is configuration centric, as
+      the reversed order happens after each configuration function and
+      not in relation to testcase.</p>
+      <p>Note that <c>ct_hooks_order</c> option is considered as a
+      global framework setting. In case when option is configured
+      multiple times framework with process only the first value.</p>
