+## Building and developing shinyDAG
+
+### shinyDAG dev environment
+
+I use the Dockerfile in this folder to create a fully-featured RStudio docker container that is *pretty close* to the final shinyDAG environment.
+Note that it's not perfect and if you install packages into this container, you'll need to also update the main shinyDAG docker file [here](../Dockerfile).
+
+To create the dev environment:
+
+```bash
+# make sure you're in the ./dev folder
+cd dev
+
+# make the dev image
+docker build -t shinydag-dev .
+
+# move back to shinyDAG proper and start up the dev image
+cd ..
+docker run --rm -p 8787:8787 -v $(pwd):/home/rstudio/shinydag -e PASSWORD="password" shinydag-dev
+```
+
+(Note that you should probably change the password above, but if you're only running locally it's not a big deal.)
+
+Then navigate to <localhost:8787> and login using the password you entered.
+
+### Create shinyDAG image
+
+```bash
+docker build -t gerkelab/shinydag:dev .
+
+# To send up to docker hub
+docker push
+```
+
+The `:dev` indicates that this image is tagged `dev`, but this can be anything you want.
+If you don't add a tag, it's assumed to be `:latest` which is kind of like git's `master` but for docker containers.
