-## Using the module
+## Preparing the Floorplan
 
 First of all, you should create an image showing your individual floorplan.
-You can use `mmm-openhabfloorplan/images/floorplan-default.png` as template and use an image editor like [paint.net](https://www.getpaint.net/index.html) to change it as you like.
+You can use `mmm-openhabfloorplan/images/floorplan-default.png` as template (shown [here](images/README.md)) and use an image editor like [paint.net](https://www.getpaint.net/index.html) to change it as you like.
 Save it as `mmm-openhabfloorplan/images/floorplan.png` (leave `floorplan-default.png` untouched).
 
+## Configuring the Module
+
 Now add the module to the modules array in the `config/config.js` file.
 Yes, the configuration looks complicated, but there is quite a lot that can be configured.
 The in-line comments should explain everything you need to know, so copy this sample configuration and adjust it to your individual openhab server, openhab items, and your floorplan.
