set your GOPATH (to something like /home/user/mygo), and make sure it's a directory that exists. (Note: Set this on your machine's environment, not in the go.bat file)
further commands that use go, dev_appserver.py, and appcfg.py all live in the google_appengine directory from the SDK. make sure it's in your $PATH.
download dependencies by running: go get -d github.com/mjibson/goread/goapp. this will download goread and all of its dependencies, and will stick them in your GOPATH.
cd $GOPATH/src/github.com/mjibson/goread
git checkout master (bug in go get)
copy app.sample.yaml to app.yaml
in the goapp folder, copy settings.go.dist to settings.go
from the goread directory, start the app with dev_appserver.py app.yaml
