+## dockerfiles
+
+This is a repo to hold various Dockerfiles for images I create.
+
+I try to make sure each has a command at the top for running it, 
+if a file you are looking at does not have a command, please
+pull request it!
+
+Almost all of these live on dockerhub under [jess](https://registry.hub.docker.com/repos/jess/).
