 First, get all prerequisites. If you cloned this repository with Git, all you

+have to do is `cd` into the repository and do a `git submodule init && git
+submodule update`. Otherwise, you need the following:
 
-Open `bottle-clip.scad` in OpenSCAD. At the end of the file, there is a
-template for 4 bottle name tags which you can adapt to build your own.
+ * [Write.scad][thing16193] and at least one font, put it into the `write/`
+   subfolder
+ * If you want a logo on your name tag, draw a DXF file by yourself, or choose
+   one out of my collection at rohieb/thing-logos. Your own logos should be no
+   more than 50mm in height, and centered on point (25,25) for optimal results.
 
+Then open `example.scad` in OpenSCAD, read it, choose an example that matches
+your expectations, comment it out (remove the `//` on the beginning of the
+line) and adapt it to your needs, or create your own. The code itself resides
+in `bottle-clip.scad` and should be documented sufficiently.
