 # 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.
+There is also a GUI for Windows Users and beginners.
+
+## 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
+```
+
+### GUI 
+
+You can also build the grapical user inteface if you want. 
+There you can manually trigger a refresh in a gui and set all the config parameters.

 ## Build
 ## Basic Build
-Download source files
+### 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 .`
+`cmake -S . -B build`
 
-compile project
+### compile project
 
 `make`
 
-install it to the system
+[root] install it to the system
 
 `make install`
 
-### Build a Debian package
-Download source files
+(optional) create Linux packages
 
-`git clone https://github.com/Lukas-Heiligenbrunner/DynuIPRefresher.git`
+`make package`
 
-rename Project folder to lower case:
+### GUI Build
 
-`mv DynuIPRefresher iprefresher-1.0`
+please use the predefined Docker-Image here: 
+[DockerHub](https://hub.docker.com/repository/docker/luki42/dynuiprefresher_build)
 
-`cd iprefresher-1.0`
-
-remove .idea folder because it´s useless in this case:
-
-`rm -Rf .idea`
-
-pack source in a tar.gz archive
-
-`tar -zcvf iprefresher-1.0.tar.gz *`
-
-create debian/ folder and create example config files
-
-`dh_make -f iprefresher-1.0.tar.gz`
-
-recently packed archive is useless now, delete it
-
-`rm iprefresher-1.0.tar.gz`
-
-move to debian/ folder:
-
-`cd debian`
-
-remove useless files:
-
-`rm *.ex *.EX README.Debian README.source `
-
-edit control file
-
-`rm control`
-
-`nano control`
-

 ### Windows cross build
-TODO!
+Set Winbuild flag in CMakeList.txt.
+
+Dependencies:
+* MinGW Compiler
+* MinGW-libcurl
+* MinGW-libconfig++
+
+Optional dependencies
+* NSIS Pack tool (for creating installer)
+* doxygen (for generating html doc)
+
+The Simplest way to install all dependencies is the preconfigured Docker-Image:
+[DockerHub](https://hub.docker.com/repository/docker/luki42/dynuiprefresher_build)
+
+`make package` will pack it into a NSIS installer for Windows.
