-#  This file allows for per-layer settings which can dynamically affect layer

+#  This file contains per-layer settings that configure layer behavior at
+#  execution time. Comments in this file are denoted with the "#" char.

+#      "<LayerIdentifier>.<SettingName> = <SettingValue>"
 #
-#  <LayerIdentifier> is typically the official layer name, minus the VK_LAYER prefix
-#  and all lower-camel-case -- i.e., for VK_LAYER_LUNARG_core_validation, the layer
-#  identifier is 'lunarg_core_validation', and for VK_LAYER_GOOGLE_threading the layer

-#  There are some common settings that are used by each layer.

+# Validation Layer Common Settings:
+# =================================
 #
 #   DEBUG_ACTION:
 #   =============
-#   <LayerIdentifier>.debug_action : This is an enum value indicating what action is to
-#    be taken when a layer wants to report information. Possible settings values
-#    are defined in the vk_layer.h header file. These settings are:
-#    VK_DBG_LAYER_ACTION_IGNORE - Take no action
-#    VK_DBG_LAYER_ACTION_LOG_MSG - Log a txt message to stdout or to a log file
-#       specified via the <LayerIdentifier>.log_filename setting (see below)

+#    Possible settings values are defined in the vk_layer.h header file.
+#    These settings are:

+#    VK_DBG_LAYER_ACTION_LOG_MSG - Log a txt message to stdout or to a log filename
+#       specified via the <LayerIdentifier>.log_filename setting (see below).
 #    VK_DBG_LAYER_ACTION_CALLBACK - Call user defined callback function(s) that
 #       have been registered via the VK_EXT_debug_report extension. Since
 #       app must register callback, this is a NOOP for the settings file.
-#    VK_DBG_LAYER_DEBUG_OUTPUT [Windows only] - Log a txt message using the Windows
-#       OutputDebugString function -- messages will show up in Visual Studio output
-#       window, for instance.
+#    VK_DBG_LAYER_DEBUG_OUTPUT [Windows only] - Log a txt message using the
+#       Windows OutputDebugString function -- messages will show up in the
+#       Visual Studio output window, for instance.
 #    VK_DBG_LAYER_ACTION_BREAK - Trigger a breakpoint.
 #
 #   REPORT_FLAGS:
 #   =============
-#   <LayerIdentifier>.report_flags : This is a comma-delineated list of options telling
-#    the layer what types of messages it should report back. Options are:
-#    info - Report informational messages
-#    warn - Report warnings from using the API in a manner which may lead to undefined
-#           behavior or to warn the user of common trouble spots. A warning does NOT
-#           necessarily signify illegal application behavior.
-#    perf - Report using the API in a way that may cause suboptimal performance
-#    error - Report errors in API usage
-#    debug - For layer development. Report messages for debugging layer behavior

+#    debug - For layer development. Report messages for debugging layer
+#            behavior.
 #
 #   LOG_FILENAME:
 #   =============
-#   <LayerIdentifier>.log_filename : output filename. Can be relative to location of
-#      vk_layer_settings.txt file, or an absolute path. If no filename is
-#      specified or if filename has invalid path, then stdout is used by default.
