 # New Features
 
-Thank you for contributing to the Jupyter Docker Stacks! We review pull requests of new features (e.g., new packages, new scripts, new flags) to balance the value of the images to the Jupyter community with the cost of maintaining the images over time.
+Thank you for contributing to the Jupyter Docker Stacks! We review pull requests of new features
+(e.g., new packages, new scripts, new flags) to balance the value of the images to the Jupyter
+community with the cost of maintaining the images over time.
 
 ## Suggesting a New Feature
 
 Please follow the process below to suggest a new feature for inclusion in one of the core stacks:
 
-1. [Open a GitHub issue](https://github.com/jupyter/docker-stacks/issues) describing the feature you'd like to contribute.
-2. Discuss with the maintainers whether the addition makes sense in [one of the core stacks](../using/selecting.md#Core-Stacks), as a [recipe in the documentation](recipes.md), as a [community stack](stacks.md), or as something else entirely.

+   [recipe in the documentation](recipes.md), as a [community stack](stacks.md), or as something
+   else entirely.
 
 ## Selection Criteria
 
 Roughly speaking, we evaluate new features based on the following criteria:
 
-* **Usefulness to Jupyter users**: Is the feature generally applicable across domains? Does it work with Jupyter Notebook, JupyterLab, JupyterHub, etc.?
-* **Fit with the image purpose**: Does the feature match the theme of the stack in which it will be added? Would it fit better in a new, community stack?
-* **Complexity of build / runtime configuration**: How many lines of code does the feature require in one of the Dockerfiles or startup scripts? Does it require new scripts entirely? Do users need to adjust how they use the images?
-* **Impact on image metrics**: How many bytes does the feature and its dependencies add to the image(s)? How many minutes do they add to the build time?
-* **Ability to support the addition**: Can existing maintainers answer user questions and address future build issues? Are the contributors interested in helping with long-term maintenance? Can we write tests to ensure the feature continues to work over time?

 1. Implement the feature in a local clone of the `jupyter/docker-stacks` project.

 # Package Updates
 
-We actively seek pull requests which update packages already included in the project Dockerfiles. This is a great way for first-time contributors to participate in developing the Jupyter Docker Stacks.

-2. Adjust the version number for the package. We prefer to pin the major and minor version number of packages so as to minimize rebuild side-effects when users submit pull requests (PRs).

+We greatly appreciate pull requests that extend the automated tests that vet the basic functionality

 ## How the Tests Work
 
-Travis executes `make build-test-all` against pull requests submitted to the `jupyter/docker-stacks` repository. This `make` command builds every docker image. After building each image, the `make` command executes `pytest` to run both image-specific tests like those in [base-notebook/test/](https://github.com/jupyter/docker-stacks/tree/master/base-notebook/test) and common tests defined in [test/](https://github.com/jupyter/docker-stacks/tree/master/test). Both kinds of tests make use of global [pytest fixtures](https://docs.pytest.org/en/latest/fixture.html) defined in the [conftest.py](https://github.com/jupyter/docker-stacks/blob/master/conftest.py) file at the root of the projects.

 ## Updating the Ubuntu Base Image
 
-When there's a security fix in the Ubuntu base image or after some time passes, it's a good idea to update the pinned SHA in the [jupyter/base-notebook Dockerfile](https://github.com/jupyter/docker-stacks/blob/master/base-notebook/Dockerfile). Submit it as a regular PR and go through the build process. Expect the build to take a while to complete: every image layer will rebuild.
