 * `text_color`: A 3-octet number defining the color of the text. The octets denote, in this order red, green and blue and range from `0x00` (complete lack of this component) to `0xFF` (full intensity of this component). Example: `0xFFFFFF` for white.
 * `label`: A string which is displayed on the HUD bar itself to describe the HUD bar. Try to keep this string short.
 * `textures`: A table with the following fields:
- * `bar`: The file name of the bar image (as string).
- * `icon`: The file name of the icon, as string. This field can be `nil`, in which case no icon will be used.
+ * `bar`: The file name of the bar image (as string). This is only used for the `progress_bar` bar type (see `README.txt`, settings section).
+ * `icon`: The file name of the icon, as string. For the `progress_bar` type, it is shown as single image left of the bar, for the two statbar bar types, it is used as the statbar icon and will be repeated. This field can be `nil`, in which case no icon will be used, but this is not recommended, because the HUD bar will be invisible if the one of the statbar bar types is used.

+After a HUD bar has been added, you can change the current and maximum value and other attributes on a per-player basis.
 You use the function `hb.change_hudbar` for this.
 
-### `hb.change_hudbar(player, identifier, new_value, new_max_value)`
-Changes the values of an initialized HUD bar for a certain player. `new_value` and `new_max_value`
-can be `nil`; if one of them is `nil`, that means the value is unchanged. If both values
-are `nil`, this function is a no-op.
-This function also tries minimize the amount of calls to `hud_change` of the Minetest Lua API, and
-therefore, network traffic. `hud_change` is only called if it is actually needed, i.e. when the
-actual length of the bar or the displayed string changed, so you do not have to worry about it.
+### `hb.change_hudbar(player, identifier, new_value, new_max_value, new_icon, new_bgicon, new_bar, new_label, new_text_color)`
+Changes the values and the appearance of an initialized HUD bar for a certain player. `new_value`
+and `new_max_value` are the most important parameters as they specify the new current and maximum new values, you do not need
+to worry too much about the other parameters.
+
+The following parameters are less important and provided for styling the HUD bar after registration (if
+this is desired). The “styling” parameters parallel the parameters of `hb.register_hudbar`. It is
+recommended to not change the style of a HUD bar too often as this can be distracting or confusing
+for players.

+or the displayed string changed, so you do not have to worry about it. There is, however, no
+such network optimization for the “styling” parameters, so keep this in mind.
 
 #### Parameters
 * `player`: `ObjectRef` of the player to which the HUD bar belongs to
 * `identifier`: The identifier of the HUD bar type to change, as specified in `hb.register_hudbar`.
 * `new_value`: The new current value of the HUD bar
 * `new_max_value`: The new maximum value of the HUD bar
+* `new_icon`: File name of the new icon
+* `new_bgicon`: File name of the new background icon for the modern-style statbar
+* `new_bar`: File name of the new bar segment image
+* `new_label`: A new text label of the HUD bar. Note the format string still applies

 Minetest mod: HUD bars
 ======================
-Version: 1.0.0

 This software uses semantic versioning, as defined by version 2.0.0 of the SemVer
 standard. <http://semver.org/>
@@ -27,6 +27,66 @@ set will use a default value instead.
 IMPORTANT:
 Keep in mind if running a server with this mod, that the custom position should be displayed correctly on every screen size!
 
+Settings:
+---------
+This mod can be configured by editing minetest.conf. Currently, the following setting is recognized:
+
+- hudbars_autohide_breath: A boolean setting, it can be either “true” or “false”. If set to “true”,
+  the breath bar will be automatically hidden shortly after the breathbar has been filled up. If set
+  to “false”, the breath bar will always be displayed. The default value is “true”.
+
+- hudbars_sorting: This setting allows you to specify the “slot” positions of the HUD bars manually.
+
+  The setting has to be specified as a comma-seperated list of key=value pairs, where a key refers to the
+  identifier of a HUD bar and the value refers to the slot number of where the HUD bar should be placed.
+  The slot number must be an integer greater of equal to 0. The slot positions start (slot 0) at the
+  bottom (nearest to hotbar in default configuration) left side, the following slot 1 is at the right
+  side, slot `2` is on the right side again, but placed over the first HUD bar (slot 0), and it goes on,
+  in a zig-zag pattern.
+  All HUD bars to which no sorting rule has been applied will fill in all slots which have not been occupied
+  by the HUD bars specified in this setting, the slots will be filled in from the lowest slot number.
+  Note that the order of those remaining HUD bars is *not* fixed, it basically just boils down on which mod
+  “came” first. Don't worry, the mod will still work perfectly fine, this setting is entirely optional.
+
+  Be careful not to use slot indices twice, or else different HUD bars will be drawn over each other!
+
+  If this setting is not set, by default the health and breath bar are displayed at slot positions 0 and 1,
+  respectively (health bar at left bottom-most positoin, breath bar right from it). All other HUD bars are
+  placed automatically.
+
+  Example value:
+    breath=0, health=1
+  This places the breath bar at the left side, and the health bar to the right side.
+
+- hudbars_bar_type: Specifies the style of bars. You can select between the default progress-bar-like bars and the good old statbars
+  like you know from vanilla Minetest. Note that the classic and modern statbars are still a little bit experimental.
+  These values are possible:
+    - progress_bar:    A horizontal progress-bar-like bar with a label, showing numerical value (current, maximum), and an icon.
+                       These bars usually convey the most information. This is the default and recommended value..
+    - statbar_classic: Classic statbar, like in vanilla Minetest. Made out of up to 20 half-symbols. Those bars represent the vague ratio between
+                       the current value and the maximum value. 1 half-symbol stands for approximately 5% of the maximum value.
+    - statbar_modern:  Like the classic statbar, but also supports background images, this kind of statbar may be considered to be more user-friendly
+                       than the classic statbar. This bar type closely resembles the [hud] mod.
+
+- hudbars_vmargin: The vertical distance between two HUD bars in pixels (default: 24)
+- hudbars_tick: The number of seconds between two updates of the HUD bars. Increase this number if you have a slow server (default: 0.1)
+
+Position settings:
+With these settings you can configure the positions of the HUD bars. All settings must be specified as a number.
+The pos settings are specified as a floating-point number between 0 to 1 each, the start_offset settings are
+specified as whole numbers, they specify a number of pixels.
+The left and right variants are used for the zig-zag mode. In the stack_up and stack_down modes, only the left variant is used for
+the base position
+
+- hudbars_pos_left_x, hudbars_pos_left_y: Screen position (x and y) of the left HUD bar in zigzag mode. 0 is left-most/top, 1 is right-most/bottom.
+	Defaults: 0.5 (x) and 1 (y)
+- hudbars_pos_right_x, hudbars_pos_right_y: Same as above, but for the right one.
+	Defaults: 0.5 and 1.
+- hudbars_start_offset_left_x, hudbars_start_offset_left_y: Offset in pixels from the basic screen position specified in hudbars_pos_left_x/hudbars_pos_left_y.
+	Defaults: -175 and -86
+- hudbars_start_offset_right_x, hudbars_start_offset_right_y: Same as above, but for the right one.
+	Defaults: 15 and -86

+[Appearance]
+# Specifies how the value indicators (i.e. health, breah, etc.) look. There are 3 styles
+# available. You can choose between the default progress-bar-like bars and the good
+# old statbars like you know from vanilla Minetest.
+# These values are possible:
+#   - progress_bar:    A horizontal progress-bar-like bar with a label, showing numerical value
+#                      (current, maximum), and an icon. These bars usually convey the most
+#                      information. This is the default and recommended value.
+#   - statbar_classic: Classic statbar, like in vanilla Minetest. Made out of up to 20
+#                      half-symbols. Those bars represent the vague ratio between
+#                      the current value and the maximum value. 1 half-symbol stands for
+#                      approximately 5% of the maximum value.
+#   - statbar_modern:  Like the classic statbar, but also supports background images, this
+#                      kind of statbar may be considered to be more user-friendly than the
+#                      classic statbar. This bar type closely resembles the mod
+#                      “Better HUD” [hud] by BlockMen.

+# This setting changes the way the HUD bars are ordered on the display. You can choose
+# between a zig-zag pattern (default) or a vertically stacked pattern.
+# The following values are allowed:
+#    - zigzag:     Starting from the left bottom, the next is right from the first,
+#                  the next is above the first, the next is right of the third, etc.

+# This setting allows you to specify the order of the HUD bars explicitly. If left empty
+# (the default), the health and breath indicators come first, additional indicators
+# may appear in any order. This setting is quite technical and normal users probably do not
+# need to worry about it.
+#
+# Syntax:
+# The setting has to be specified as a comma-seperated list of key=value pairs, where a key
+# refers to the identifier of a HUD bar and the value refers to the slot number of where the
+# HUD bar should be placed. The slot number must be an integer greater of equal to 0. Where
+# the HUD bars will be displayed exactly depends on the alignment pattern being used.
+# All HUD bars to which no order value has been applied will fill in all slots which have
+# not been occupied by the HUD bars specified in this setting, the slots will be filled in
+# from the lowest slot number.
+# Note that the order of those remaining HUD bars is not fixed, it basically just boils
+# down on which mod “came” first. Don't worry, the mod will still work perfectly fine, this
+# setting is entirely optional.
+# The identifier for the health bar is “health” and the identifier for the breath bar is
+# “breath”. For other HUD bars, you have to learn it from the mod which is supplying them.
+#
+# Be careful not to use slot indices twice, or else different HUD bars will be drawn over
+# each other!
+#
+# Example: “breath=0, health=1”
+# This makes the breath bar first and the health bar second, which is the opposite order
+# of the default one.
