+## Build from source
+
+`mas` currently requires the [bundler](http://bundler.io/) RubyGem in order to 
+bootstrap and build the project. There are a number ways to install bundler but
+if you have never used it before then installing it with `gem` should be enough.
+
+```
+$ gem install bundler
+```
+
+You can now bootstrap the project by executing the `bootstrap` script
+from the mas sources script directory:
+
+```
+$ script/bootstrap
+```
+
+You can now build from Xcode by opening `mas-cli.xcodeproj`, or from the Terminal:
+
+```
+$ script/build
+```
+
+Build output can be found in the `build/` directory within the project.
