+# NAME
+
+waybar - backlight slider module
+
+# DESCRIPTION
+
+The *backlight slider* module displays and controls the current brightness of the default or preferred device.
+
+The brightness can be controlled by dragging the slider across the bar or clicking on a specific position.
+
+# CONFIGURATION
+
+*min*: ++
+    typeof: int ++
+    default: 0 ++
+    The minimum volume value the slider should display and set.
+
+*max*: ++
+    typeof: int ++
+    default: 100 ++
+    The maximum volume value the slider should display and set.
+
+*orientation*: ++
+    typeof: string ++
+    default: horizontal ++
+    The orientation of the slider. Can be either `horizontal` or `vertical`.
+
+*device*: ++
+    typeof: string ++
+    The name of the preferred device to control. If left empty, a device will be chosen automatically.

+    Controls the style of the part of the bar that has not been filled.
+
+*#backlight-slider highlight*: ++
+    Controls the style of the part of the bar that has been filled.
+
+## STYLE EXAMPLE

+# SOLVING ISSUES
+
+. On start Waybar throws an exception "error while loading shared libraries: libcava.so: cannot open shared object file: No such file or directory".
+  It might happen when libcava for some reason hasn't been registered in the system. sudo ldconfig should help
+. Waybar is starting but cava module doesn't react to the music
+	1. In such cases at first need to make sure usual cava application is working as well
+	2. If so, need to comment all configuration options. Uncomment cava_config and provide the path to the working cava config
+	3. You might set too huge or too small input_delay. Try to setup to 4 seconds, restart waybar, and check again 4 seconds past. Usual even on weak machines it should be enough
+	4. You might accidentally switch action mode to pause mode
+
+# RISING ISSUES
+
+For clear understanding: this module is a cava API's consumer. So for any bugs related to cava engine you should contact Cava upstream(https://github.com/karlstav/cava) ++
+with the one Exception. Cava upstream doesn't provide cava as a shared library. For that, this module author made a fork libcava(https://github.com/LukashonakV/cava). ++
+So the order is:
+. cava upstream
+. libcava upstream.
+In case when cava releases new version and you're wanna get it, it should be raised an issue to libcava(https://github.com/LukashonakV/cava) with title ++
+\[Bump\]x.x.x where x.x.x is cava release version.

+# Troubleshooting
+
+If clock module is disabled at startup with locale::facet::\_S\_create\_c\_locale ++
+name not valid error message try one of the following:
+
+- check if LC_TIME is set properly (glibc)
+- set locale to C in the config file (musl)
+
+The locale option must be set for {calendar} to use the correct start-of-week, regardless of system locale.
+
+## Calendar in Chinese. Alignment
+
+In order to have aligned Chinese calendar there are some useful recommendations:
+
+. Use "WenQuanYi Zen Hei Mono" which is provided in most Linux distributions
+. Try different font sizes and find best for you. size = 9pt should be fine
+. In case when "WenQuanYi Zen Hei Mono" font is used disable monospace font pango tag
