 Models have their dimensions and sizes pulled from existing specifications, organized by PVC schedule and size, so they should be sized the same as parts found in a hardware store. PVC parts modeled here come with simple BOSL2 attachable endpoints, so joining parts together relatively easy when constructing pipe layouts or new component parts.
 
-# Usage
-
-Models start by selecting a PVC specification. A range of public PVC specifications are inline to the library: they define diameters and thicknesses and thread sizing for existing piping. 
-
-Once a specification is selected, it can be reused over and over to create individual PVC parts. 
-
-Individual PVC parts can be quickly modeled and attached to each other using BOSL2's Attachment feature. 
-
-A simple example:
-
-```
+```openscad
 pvc = pvc_spec_lookup(schedule=40, dn="DN20");
 pvc_flange(pvc)
     attach("B", "A")

 # Installation
-
 Installing this library should be as simple as downloading the .scad file and copying it to your OpenSCAD library directory:
 ```
 wget -N -q -O openscad_pvc.scad https://raw.githubusercontent.com/jon-gilbert/openscad_pvc/main/openscad_pvc.scad
 ```
-The library directory will vary based on your OS; see https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Libraries#Library_locations for the correct location for you.
