 * `default_max_value`: If this HUD bar is added to a player, and no initial maximum value is specified, this value will be used as initial maximum value
 * `default_start_hidden`: The HUD bar will be initially start hidden by default when added to a player. Use `hb.unhide_hudbar` to unhide it.
-* `format_string`: This is optional; You can specify an alternative format string display the final text on the HUD bar. The default format string is “`%s: %d/%d`” (in this order: Label, current value, maximum value). See also the Lua documentation of `string.format`.
+* `format_string`: Optional; You can specify an alternative format string to use for the final text on the HUD bar. The default format string is “`@1: @2/@3`” (The “@” numbers are placeholders that have a meaning in this order: @1 = Label, @2 = current value, @3 = maximum value). Do *not* use minetest.translator on this string, the string will be translated by `hudbars`, but you still must put this string into the translation catalogue file.
+* `format_string_config`: Required if `format_string` is set. This allows to change which parameters to use in the format string. It's a table with these fields:
+ * `textdomain`: Text domain of the format string, used by `minetest.translate`
+ * `order`: Table that contains the order of the placeholders. It's also possible to remove placeholders. Default order: `{ "label", "value", "max_value" }`
+ * `format_value`: Format string to apply when displaying `value`. Syntax is same as in `string.format`. Default: `"%d"`
+ * `format_max_value`: Same as `format_value` but is applied to `max_value`
+
+#### Example
+Example (mostly) from `hbarmor` mod:
+
+```
+hb.register_hudbar("armor", 0xFFFFFF, minetest.translator("hbarmor", "Armor"), { icon = "hbarmor_icon.png", bgicon = "hbarmor_bgicon.png", bar = "hbarmor_bar.png" }, 0, 100, hbarmor.autohide, N("@1: @2%"), { order = { "label", "value" }, textdomain = "hbarmor" } )
+```
+
+Displays an armor HUD bar with a label of the form „Armor: 53%“. (`N` is a dummy function that returns its argument, used to make the string visible for translator scripts.)
 
 #### Return value
 Always `nil`.

-
-0.1.0
------
-- Initial release, forked from mod “Better HUD” [hud].
-
-0.2.0
------
-- Add API documentation
-
-0.3.0
------
-- Rename main table from “hud” to “hb” (affects function names!)
-- Arguments 3-4 of hb.change_hudbar can be nil for values which should not change
-- Add proper function hb.init_hudbar, replaces odd call to hud.hudtables[identifier].add_all
-- Update API documentation and fix mistakes
-- Use “hudbars.conf” instead of “hud.conf”
-
-0.4.0
------
-- New function: hb.get_hudbar_state to get information about the state of an active HUD bar, such as values, whether it is hidden, etc.
-- hb.change_hudbar has been optimized to call hud_change fewer times, which is hopefully good for networking
-- Rename hb.register_hudbar parameter “start_hide” to “start_hidden”
-- start_hidden parameter now finally works
-- Do not affect other HUD flags (crosshair, wielditem, etc.) when starting mod
-- Show error message when trying to call hb.init_hudbar or hb.change_hudbar with bad values
-- Update documentation
-- Lots of refactoring
-- Health and breath bar now use API
-
-1.0.0
------
-- Add new parameter start_hidden to hb.init_hudbar, specified whether HUD bar is hidden on start
-- Copy-editing of API.md and README.txt
-- Internal: Fix add_all weirdness
-
-1.0.1
------
-- Fix race condition causing crash at start of server
-
-1.0.2
------
-- Fix other HUD elements disappearing for rejoining players
-- Remove pointless delays for initializing the HUD for new or rejoining players
-
-1.0.3
------
-- Adjust default HUD bars position for Minetest 0.4.12
-
-1.1.0
------
-- Add boolean minetest.conf setting support (hudbars_autohide_breathbar) to control whether the breath bar is automatically hidden when full (default: yes)
-
-1.2.0
------
-- New setting: hudbars_sorting. You can now manually sort all the HUD bars. Useful if you don't like automatic order
-- New setting: hudbars_bar_type. You now can change the appearance of the HUD bars.
-- New HUD bar types, slightly experimental: Classic statbars and modern [hud]-style statbars
-- New experimental/unfinished setting: hudbars_alignment_pattern: You can now make the HUD bars stack vertically instead of the current zig-zag pattern. Note you probably need to change source code to productively use this feature
-- Various position-related HUD bar settings (see README.txt)
-- Remove hudbars.conf support and hudbars.conf.example (was never officially supported anyways)
-
-1.2.1
------
-- Fix crash when enable_damage is changed in mid-game
-
-1.3.0
------
-- Make all settings avaialbe in Minetest's advanced settings menu
-- Fix HUD bars overlap when both hudbars_tick and hudbars_vmargin were set
-- Use Markdown syntax in readme file
-- Fix some factual mistakes in readme file
-- Add metadata: mod.conf, description.txt, screenshot.png
-
-1.4.0
------
-- Allow to change HUD bar images and label after it has been registered
-- Minor API.md correction
