+*{icon}*: Icon, as defined in *format-icons*.
+
+*{time}*: Estimate of time until full or empty. Note that this is based on the power draw at the last refresh time, not an average.
+
+# TIME FORMAT
+
+The *battery* module allows you to define how time should be formatted via *format-time*.
+
+The two arguments are:
+*{H}*: Hours
+*{M}*: Minutes
+
+# CUSTOM FORMATS
+
+The *battery* module allows to define custom formats based on up to two factors. The best fitting format will be selected.
+
+*format-<state>*: With *states*, a custom format can be set depending on the capacity of your battery.
+
+*format-<status>*: With the status, a custom format can be set depending on the status in /sys/class/power_supply/<bat>/status (in lowercase).
+
+*format-<status>-<state>*: You can also set a custom format depending on both values.
+
+# STATES
+
+- Every entry (*state*) consists of a *<name>* (typeof: *string*) and a *<value>* (typeof: *integer*).
+	- The state can be addressed as a CSS class in the *style.css*. The name of the CSS class is the *<name>* of the state.	Each class gets activated when the current capacity is equal or below the configured *<value>*.
+	- Also each state can have its own *format*. Those con be configured via *format-<name>*. Or if you want to differentiate a bit more even as *format-<status>-<state>*. For more information see *custom-formats*.
+
+
+
+# EXAMPLES
+
+```
+"battery": {
+    "bat": "BAT2",
+    "interval": 60,
+    "states": {
+        "warning": 30,

+    "format-icons": ["", "", "", "", ""],
+    "max-length": 25
+}
+```
+
+# STYLE
+
+- *#battery*
+- *#battery.<status>*
+	- *<status>* is the value of /sys/class/power_supply/<bat>/status in lowercase.
+- *#battery.<state>*
+	- *<state>* can be defined in the *config*. For more information see *states*.
+- *#battery.<status>.<state>*
+	- Combination of both *<status>* and *<state>*.

+
+# OVERVIEW
+
+Some modules support 'states' which allows percentage values to be used as styling triggers to
+apply a class when the value matches the declared state value.
+
+# STATES
+
+- Every entry (*state*) consists of a *<name>* (typeof: *string*) and a *<value>* (typeof: *integer*).
+
+	- The state can be addressed as a CSS class in the *style.css*. The name of the CSS class is the *<name>* of the state.
+	  Each class gets activated when the current capacity is equal or below the configured *<value>*.
+
+	- Also each state can have its own *format*.
+	  Those con be configured via *format-<name>*.
+	  Or if you want to differentiate a bit more even as *format-<status>-<state>*.
+
+# EXAMPLE
+
+```
+"battery": {
+	"bat": "BAT2",
+	"interval": 60,
+	"states": {
+		"warning": 30,
+		"critical": 15
+	},
+	"format": "{capacity}% {icon}",
+	"format-icons": ["", "", "", "", ""],
+	"max-length": 25
+}
+```
+
+# STYLING STATES
+
+- *#battery.<state>*
+  - *<state>* can be defined in the *config*.

+# EXAMPLE:
+
+- *#battery.warning: { background: orange; }*

+# MODULE FORMAT
+
+You can use PangoMarkupFormat (See https://developer.gnome.org/pango/stable/PangoMarkupFormat.html#PangoMarkupFormat).
+
+e.g.
+
+```
+"format": "<span style=\"italic\">{}</span>"
+```
+# MULTIPLE INSTANCES OF A MODULE
+
+If you want to have a second instance of a module, you can suffix it by a '#' and a custom name.
+For example if you want a second battery module, you can add *"battery#bat2"* to your modules.
+To configure the newly added module, you then also add a module configuration with the same name.
+
+This could then look something like this *(this is an incomplete example)*:
+
+```
+"modules-right": ["battery", "battery#bat2"],
+"battery": {
+	"bat": "BAT1"
+},
+"battery#bat2": {
+	"bat": "BAT2"
+}
+```
+
+# MINIMAL CONFIGURATION
+
+A minimal *config* file could look like this:
+
+```
+{
+	"layer": "top",
+	"modules-left": ["sway/workspaces", "sway/mode"],
+	"modules-center": ["sway/window"],
+	"modules-right": ["battery", "clock"],
+	"sway/window": {
+		"max-length": 50
+	},
+	"battery": {
+		"format": "{capacity}% {icon}",
+		"format-icons": ["", "", "", "", ""]
+	},
+	"clock": {
+		"format-alt": "{:%a, %d. %b  %H:%M}"
+	}
+}
+```
+
+# MULTI OUTPUT CONFIGURATION
+
+## Limit a configuration to some outputs
+
+```
+{
+	"layer": "top",
+	"output": "eDP-1",
+	"modules-left": ["sway/workspaces", "sway/mode"],
+	...
+
+}
+
+```
+
+```
+{
+	"layer": "top",
+	"output": ["eDP-1", "VGA"],
+	"modules-left": ["sway/workspaces", "sway/mode"],
+	...
+}
+
+```
+
+## Configuration of multiple outputs
+
+Don't specify an output to create multiple bars on the same screen.
+
+```
+[{
+	"layer": "top",
+	"output": "eDP-1",
+	"modules-left": ["sway/workspaces", "sway/mode"],
+	...
+}, {
+	"layer": "top",
+	"output": "VGA",
+	"modules-right": ["clock"],
+	...
+}]
+
+```
+
+## Rotating modules
+
+When positioning Waybar on the left or right side of the screen, sometimes it's useful to be able to rotate the contents of a module so the text runs vertically. This can be done using the "rotate" property of the module. Example:
+
+```
+{
+	"clock": {
+		"rotate": 90
+	}
+}
+```
+
+Valid options for the "rotate" property are: 0, 90, 180 and 270.
