+slstatus - suckless status
+==========================
+slstatus is a small tool for providing system status information to other
+programs over the EWMH property of the root window (used by dwm(1)) or
+standard input/output. It is designed to be as efficient as possible by
+only issuing the minimum of system calls required.
+
+
+Features
+--------
+- Battery percentage/state/time left
+- Cat (read file)
+- CPU usage
+- CPU frequency
+- Custom shell commands
+- Date and time
+- Disk status (free storage, percentage, total storage and used storage)
+- Available entropy
+- Username/GID/UID
+- Hostname
+- IP address (IPv4 and IPv6), interface status
+- Kernel version
+- Keyboard indicators
+- Keymap
+- Load average
+- Network speeds (RX and TX)
+- Number of files in a directory (hint: Maildir)
+- Memory status (free memory, percentage, total memory and used memory)
+- Swap status (free swap, percentage, total swap and used swap)
+- Temperature
+- Uptime
+- Volume percentage
+- WiFi signal percentage and ESSID
+
+
+Requirements
+------------
+Currently slstatus works on FreeBSD, Linux and OpenBSD.
+In order to build slstatus you need the Xlib header files.
+
+- For volume percentage on Linux the kernel module `snd-mixer-oss` must be
+  loaded.
+- For volume percentage on FreeBSD, `sndio` must be installed.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (slstatus is installed into the
+/usr/local namespace by default).
+
+Afterwards enter the following command to build and install slstatus (if
+necessary as root):
+
+    make clean install
+
+
+Running slstatus
+----------------
+See the man page for details.
+
+
+Configuration
+-------------
+slstatus can be customized by creating a custom config.h and (re)compiling the
+source code. This keeps it fast, secure and simple.
