 # Example of Linux Daemon
 
 This repository contains simple example of daemon for Linux OS.
+This repository also contains examples of starting scripts.
 
+## Requirements
+
+To build example of the daemon you have to have following tools
+
+* CMake
+* GCC/CLang
+
+## Build
+
+To build example of daemon you have to type following commands:
+
+    git clone https://github.com/jirihnidek/daemon.git
+    cd daemon
+    mkdir build
+    cd build
+    cmake ../
+    make
+
+## Usage
+
+You can test running daemon from command line:
+
+    ./bin/daemon
+
+But running the app in this way is not running running daemon. Let
+have a look at command line parameters and arguments
+
+    Usage: ./bin/daemon [OPTIONS]
+
+     Options:
+      -h --help                 Print this help
+      -c --conf_file filename   Read configuration from the file
+      -t --test_conf filename   Test configuration file
+      -l --log_file  filename   Write logs to the file
+      -d --daemon               Daemonize this application
+      -p --pid_file  filename   PID file used by daemonized app
+
+When you will run `./bin/daemon` with parameter `--daemon` or `-d`, then
+it will become real UNIX daemon.
