+Ebook-Server for IT-internal use. Using Calibre-Web.
+
+## Install
+You will need to get calibre-web first. Just run 
+
+```bash
+git clone https://github.com/janeczku/calibre-web.git
+```
+
+and put it in this directory, so docker can find it and put it into the image.
+
+Then run
+```bash
+docker build -t calibre-web .
+´´´
+to start the build. Afterwards you'll have a docker-image called **'calibre-web'** on your system.
+
+To run/spawn your container, you will need to run
+```bash
+docker run -p 8083:8083 -v /path/to/calibre/libary:/ebooks --name myebookserver -d calibre-web
