+## Tips and Tricks
+
+To hack on docker and develop a patch do these steps:
+
+```
+git clone https://github.com/docker/docker
+cd docker
+ln -s ../../../../ vendor/src/github.com/docker/docker
+./hack/make.sh dynbinary
+```
+
+Then add some symlinks:
+
+```
+ln -s $PWD/bundles/VERSION-OF-DOCKER-dev/dynbinary/docker /usr/local/bin/docker
+ln -s $PWD/bundles/VERSION-OF-DOCKER-dev/dynbinary/dockerinit /usr/local/bin/dockerinit
+```
