 ### Coding Guidelines
 
-* **Code style:** py4DSTEM uses the black code formatter and flake8 linter. All code must pass these checks without error before it can be merged. We suggest using `pre-commit` to help ensure any code commited follows these practices, checkout the [setting up developer environment section below](#install). We also try to abide by PEP8 coding style guide where possible.

 * **Documentation:** All code should be well-documented, and use Numpy style docstrings. Use docstrings to document functions and classes, add comments to explain complex code both blocks and individual lines, and use informative variable names.
 
-* **Testing:** Ideally all new code should be accompanied by tests using pyTest framework; at the least we require examples of old and new behaviour caused by the PR. For bug fixes this can be a block of code which currently fails and works with the proposed changes. For new workflows or extensive feature additions, please also include a Jupyter notebook demonstrating the changes for an entire workflow i.e. from loading the input data to visualizing and saving any processed results.

 * **Dependencies:** New dependencies represent a significant change to the package, and any PRs which add new dependencies will require discussion and agreement from the development team. If a new dependency is required, please prioritize adding dependencies that are actively maintained, have permissive installation requirements, and are accessible through both pip and conda.

 This will setup pre-commit to work on this repo by creating/changing a file in .git/hooks/pre-commit, which tells `pre-commit` to automatically run flake8 and black when you try to commit code.  It won't affect any other repos.
