 There's a few libraries out there that wrap git cli commands, parsing the output and such. This is a perfectly acceptable solution. Node-gitteh provides first-class support to work with a git repository on a low level, and does not require git.git (and its myriad of dependencies) to be installed in the server environment.
 
-[Documentation can be found here](http://libgit2.github.com/node-gitteh/docs/index.html). You should also check out the examples in the examples/ dir in the repo.
+The documentation is currently outdated. We're working on a new version currently for the new 0.17.x version of gitteh. The [Old pre-0.17.x documentation can be found here](http://libgit2.github.com/node-gitteh/docs/index.html). Instead, you should visit [`examples`](https://github.com/libgit2/node-gitteh/tree/master/examples) dir in the repo to see examples of 0.17.x usage.

+### Building
+
+In order to build Gitteh, you first need to install coffee-script.
+[Coffee-script](http://coffeescript.org/) is not needed to use the library, only to 
+work with the source.
+
+    npm install -g coffee-script
+
+Next, you need to install gitteh's dependencies. In gitteh's root directory, run:
+
+    npm install
+
+Lastly, you need to compile and build gitteh
+
+    cake build
+
+It should generate `lib/gitteh.js` for you to use. Happy hacking!
