 Getting Started

-A simple installer is now available - just [download it from
-GitHub](https://github.com/rpavlik/sketchupToOSG/releases). If you
-would prefer to do it the hard way, see "Manual Installation," below.
+The preferred way to install extensions into SketchUp is now using an
+`.rbz` file. See [these instructions][install-rbz] in the SketchUp
+documentation on how to do this.

+[install-rbz]:http://help.sketchup.com/en/article/38583
+
+We also (for some versions, at least) have some Windows `.exe`
+installers or Mac `.pkg` available. This used to be super cool, but is
+harder for us to maintain and isn't nearly as necessary since 8.0 M2
+simplified extension installation with `.rbz` support.

 No matter how you install, the results are the same. SketchUp should
 have an Export to OpenSceneGraph menu under File next time you start it.

-The installers are compatible with Google SketchUp 8, Google SketchUp Pro 8,

+Generating .rbz Files
+---------------------
+On a system with a `sh`-compatible shell (Mac or Linux, and possibly

+To build all, run:

+To build just a single variant:
+

 Generating Installers

+### Windows
 There's a `setup_X.iss` file for each version of SketchUp that defines a
 few specific items then includes the shared `setup.iss` file. Using Inno Setup 5
