 # DynuIPRefresher
+A lightweight C++ application to setup a service for refreshing a dynamic IP to the Dynu servers. 
+Dynu.com is a free DDns service and provides an API.
+
+## Installation
+Download the latest Release at [Release_Page](https://github.com/Lukas-Heiligenbrunner/DynuIPRefresher/releases).
+I'm providing executables for Debian/Ubuntu (.deb) and RHEL/Debian (.rpm). 
+But you can still compile the code my your own (see build section).
+
+## Configuration
+There is a configuration file `/etc/dynuiprefresher.cfg` where you have to specify the DYNU API key (get it from their homepage), the domainid and your domain.
+Furthermore, you can optionally specify a Telegram API key and a Chat ID if you want to be notfied when your local ip changes.
+
+To enable and start the service: 
+`systemctl enable dynuiprefresher.service` and `systemctl start dynuiprefresher.service`
+
+## Usage
+First of all configure the right keys in the `/etc/dynuiprefresher.cfg` or `%appdata%\DynuIpRefresher\dynuiprefresher.cfg` config file.
+
+Afterwards use the following options: 
+
+```
+help page: 
+[-h] [--help]  print this help page
+[-v] [--version] print the software version
+[-f] [--force] force refresh of ip
+[-l] [--loop] infinite loop to refresh ip every five minutes
+[-c] [--checkconfig] validate configuration
+[-ip] [--currentip] get current global ip
+[no argument] normal ip check and refresh
+```
+
