+3.7.6  ATTRIBUTE MULTIPLIERS
+
+Making a balanced zombie map is difficult, and all maps have different balance.
+The knock back and other settings may work fine on one map, but not on other
+maps. This is where multipliers are useful.
+
+With class attribute multipliers, numeric class attributes can be scaled and
+configured with map configuration files. There's a set of multipliers for both
+humans and zombies.
+
+Warning: Currently these multipliers aren't validated, so using too high or
+         negative values may cause unexpected behaviour, or even crash the
+         plugin.
+
+Attribute multipliers are set using this console command:
+
+    Syntax:
+    ===========================================================================
+    zr_class_set_multiplier <team> <attribute> <value>
+    ---------------------------------------------------------------------------
+        Sets the multiplier on a class attribute.
+        
+        Parameters:
+        team            What multiplier set to use.
+                        Options: "zombies" or "humans"
+        attribute       A numeric class attribute. See Class Attributes (3.7.2)
+                        for details on attributes. Valid attribute multipliers:
+                        "napalm_time" (zombies only)
+                        "health"
+                        "health_regen_interval"
+                        "health_regen_amount"
+                        "health_infect_gain" (zombies only)
+                        "speed"
+                        "knockback" (zombies only)
+                        "jump_height"
+                        "jump_distance"
+        value           The multiplier to set. Note that a multiplier might be
+                        very sensitive to big change.
+                        Default: 1.0
+
+Multipliers can also be adjusted in the zombie admin menu, but the changes
+aren't saved. The menu is useful for finding the correct value, and then use it
+in a map configuration file.
