226+If you're impatient and would like to build the Docker image on the
227+build server instead of waiting for Docker Hub, you can run the
228+following command:
229+
230+```
231+DIR=$(mktemp -d)
232+(cd $DIR \
233+ && git clone https://github.com/fpco/stackage \
234+ && cd stackage \
235+ && docker build --tag snoyberg/stackage:nightly .)
236+rm -rf $DIR
237+```
238+
239+Note that we do a clean clone of the `stackage` repo instead of using
240+the existing checkout because of how `docker build` works: it will
241+send the entire local directory contents as context to the Docker
242+daemon, which in the case of the build tree is a _lot_ of content. (We
243+can discuss the wisdom—or lack thereof—of Docker's
244+approach separately.)
