+# 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/iprefresher.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.
+
+
+## Build
+## Basic Build
+### Download source files
+
+`git clone https://github.com/Lukas-Heiligenbrunner/DynuIPRefresher.git`
+
+### install build dependencies
+
+`libcurl`
+`libconfig`
+
+#### Debian:
+`apt install libcurl4-openssl-dev`
+
+#### Fedora:
+`dnf install libcurl-devel libconfig-devel`
+
+#### Alpine Linux:
+Compiler dependencies:
+
+`apk add make cmake g++`
+
+Lib dependencies:
+
+`apk add libcurl curl-dev libconfig libconfig-dev`
+
+Packaging dependencies:
+
+`apk add dpkg rpm`
+
+
+#### dependencies for package build
+`dpkg` --> debian/ubuntu package
+
+`rpmbuild` --> Fedora/RedHat/CentOS package
+
+### cmake project
+cd into downloaded files and Generate makefiles:
+
+`cmake -S . -B build`
+
+### compile project
+
+`make`
+
+[root] install it to the system
+
+`make install`
+
+(optional) create Linux packages
+
+`make package`
+
+
+
+### Windows cross build
+TODO!
