-**slstatus** is a suckless and lightweight status monitor for window managers that use WM_NAME as statusbar (e.g. DWM). It is written in pure C without any system calls and only reads from files most of the time. It is meant to be a better alternative to Bash scripts (inefficient) and Conky (bloated for this use).
+**slstatus** is a suckless and lightweight status monitor for window managers that use WM_NAME as statusbar (e.g. DWM) or any other status bars if they support reading/piping from slstatus. It is written in pure C without any extern programs being executed and only reads from files most of the time. slstatus is meant to be a better alternative to Bash scripts (inefficient) and Conky (bloated and written in C++).

 
 

-If you write a bash script that shows system information in WM_NAME, it executes a huge amount of external commands (top, free etc.) every few seconds. This results in high system resource usage. slstatus solves this problem by only using C libraries and/or reading from files in sysfs/procfs.

-Looking at the LOC (lines of code) of the [Conky project](https://github.com/brndnmtthws/conky), very interesting: *28.346 lines C++, 219 lines Python and 110 lines Lua*. slstatus currently has about **800 lines of clean documented C code** and even includes additional possibilities as it can be customized and extended very easily. Configure it by customizing the config.h (C header file) which is secure and fast as no config files are parsed at runtime.

-Multiple entries per function are supported and everything can be reordered and customized via the C header file config.h (similar to DWM).

 ## Usage
 
 ### Installation
 

-Before you continue, please be sure that a C compiler (preferrably gcc), GNU make and `alsa-lib` (for volume percentage) are installed. Then copy config.def.h to config.h and customize it to fit your needs. Recompile and install it after modifications:
+Be sure you satisfy the dependencies: X11 and optionally ALSA (for volume percentage, I will *not* support PulseAudio).
+Also you should have basic development tools like a C compiler and GNU make installed.
+Then copy config.def.h to config.h and customize it to your needs.
+(Re)Compile (and install) it (after modifications):

 
        $ make clean all
        # make install
 
 ### Starting
 
 
        $ make clean all
        # make install
 
 ### Starting
 

-Write the following code to your ~/.xinitrc (or any other initialization script):
+If you use DWM or any other window manager that uses WM_NAME, write the following code to ~/.xinitrc (or any other initialization script) to start slstatus automatically:

 
 

-       while true; do
-               slstatus
-       done &
+       slstatus -d

 
 

-The loop is needed that the program runs after suspend to ram.
+If you use any other status bar or window manager you will have to figure it out yourself. Something like this could fit your requirements:
+
+       slstatus -o | other_status_bar &
+
+### Specific function quirks
+
+- Volume percentage
+
+If there is no `/dev/mixer` on your system and you use ALSA, it means you have to load the OSS compatibility module by issuing:
+
+```
+# modprobe snd-pcm-oss
+```
