 **PRE-REQUISITE KNOWLEDGE:**  
 This document assumes the reader is familiar with Linux/UNIX, the Python programming language and DMR.  
 
+**Using docker version**
+
+To work with provided docker setup you will need:
+* A private repository with your configuration files (all .cfg files in repo will be copyed to the application root directory on start up)
+* A service user able to read your private repository (or be brave and publish your configuration, or be really brave and give your username and password to the docker)
+* A server with docker installed
+* Follow this simple steps:
+
+Build your own image from source
+
+```bash
+
+docker build . -t millaguie/hblink:3.0.0
+
+```
+
+Or user a prebuilt one in docker hub: millaguie/hblink:3.0.0
+
+Wake up your container
+
+```bash
+touch /var/log/hblink.log
+chown 65000  /var/log/hblink.log
+ run -v /var/log/hblink.log:/var/log/hblink.log -e GIT_USER=$USER -e GIT_PASSWORD=$PASSWORD -e GIT_REPO=$URL_TO_REPO_WITHOUT_HTTPS://  -p 54000:54000  millaguie/hblink:3.0.0
