+# Community Stacks
+
+We love to see the community create and share new Jupyter Docker images. We've created a [cookiecutter project](https://github.com/jupyter/cookiecutter-docker-stacks) and the documentation below as one way to get started defining, building, and sharing your Jupyter environments in Docker. If you choose to follow these steps, you will:
+
+1. Setup a project on GitHub containing a Dockerfile based on either the `jupyter/base-notebook` or `jupyter/minimal-notebook` image.
+2. Configure Travis CI to build and test your image when users submit pull requests to your repository.
+3. Configure Docker Cloud to build and host your images for others to use.
+4. Update the [list of community stacks](../using/selecting.html#community-stacks) in this documentation to include your image.
+
+This approach mirrors how we build and share the core stack images. Again, it just one of many approaches you might choose to take to share your creations.
+
+## Creating a Project
+
+First, install [cookiecutter](https://github.com/audreyr/cookiecutter) using pip or conda:
+
+```
+pip install cookiecutter   # or conda install cookiecutter
+```
+
+Run the cookiecutter command pointing to the [jupyter/cookiecutter-docker-stacks](https://github.com/jupyter/cookiecutter-docker-stacks) project on GitHub.
+
+```
+cookiecutter https://github.com/jupyter/cookiecutter-docker-stacks.git
+```
+
+Enter a name for your new stack image. This will serve as both the git repository
+name and the part of the Docker image name after the slash.
+
+```
+stack_name [my-jupyter-stack]:
+```
+
+Enter the user or organization name under which this stack will reside on
+Docker Cloud / Hub. You must have access to manage this Docker Cloud org in
+order to push images here and setup automated builds.
+
+```
+stack_org [my-project]:
+```
+
+Select an image from the jupyter/docker-stacks project that will serve as the
+base for your new image.
+
+```
+stack_base_image [jupyter/base-notebook]:
+```
+
+Enter a longer description of the stack for your README.
+
+```
+stack_description [my-jupyter-stack is a community maintained Jupyter Docker Stack image]:
+```
+
+Initialize your project as a Git repository and push it to GitHub.
+
+```
+cd <stack_name you chose>
+
+git init
+git add .
+git commit -m 'Seed repo'
+git remote add origin <url from github>
+git push -u origin master
+```
