+The h_da thesis template ships with two Dockerfiles that create [Docker](https://www.docker.com) container used to compile the LaTeX code. One container - build by the [Dockerfile.travis]( https://github.com/mbredel/thesis-template/blob/master/Dockerfile.travis) Docker file - is used by the Travis-CI infrastructure to compile the thesis template and check its integrity at every commit. The other one - created by the [Dockerfile.local](https://github.com/mbredel/thesis-template/blob/master/Dockerfile.local) Docker file might be uesed to build the Docker container that allows to compile the Latex code on your local machine without the need to install any Latex files.
 
+On order to build the Docker image you have to type the following command:
+
+```
+ $ docker build --tag mbredel/thesis-template --file Dockerfile.local .
 ```
- $ docker build --tag mbredel/thesis-template .
+
+Creating the image requires a working (and hopefully fast) Internet connection. It may take several minutes to download the requrired base-images as well as all needed dependencies. You only have to create the image once. When the image is build, you can run the Docker container by executing the following commad

 ```
+ $ docker run --volume $(pwd):/thesis-template/ mbredel/thesis-template && docker rm $(docker ps -lq)
+ ```

However, please note that additional steps are needed to create the PDF file and copy it from the Docker container to your host.
