+Bottle clip with name and logo
+==============================
+
+This thing is a simple clip with your name on it which can be used to mark your
+bottles. It is based on a previous work of Thingiverse user daniel.
+TODO thingiverse link
+
+The clip is customizable and you can tweak the following parameters:
+
+ * radius on the upper and lower side, for easy adaptation to other bottle
+	 types. The script includes examples for standard 0.5l Club Mate bottles as
+	 well as german 0.33l bottles.
+ * wall thickness (though the default should be okay for easy clipping)
+ 
+
+Instructions
+------------
+
+Open `bottle-clip.scad` in OpenSCAD. At the end of the file, there
