Contributing Guide

This tutorial repository is a great opportunity to start contributing to Xarray.

  • Report bugs, request features or submit feedback as a GitHub Issue. First check existing issues !

  • Make fixes, add content or improvements using GitHub Pull Requests, the sections below go over this process in more detail:

The Project Pythia Foundations material on  [Github](https://foundations.projectpythia.org/foundations/getting-started-github.html) and Github workflows is a great place to start if you are new to this.

Content Guidelines

Please note that examples submitted to this repository should follow these guidelines:

  1. Run top-to-bottom without intervention from the user
  2. Not require external data sources that may disappear over time (external data sources that are highly unlikely to disappear are fine). Small datasets for tutorial purposes can be added here if necessary.
  3. Not be resource intensive, and should run within 2GB of memory
  4. Be clear and contain enough prose to explain the topic at hand
  5. Be concise and limited to one or two topics, such that a reader can get through the example within a few minutes of reading
  6. Be of general relevance to Xarray users, and so not too specific on a particular problem or use case.

Fork this repository

We recommend first forking this repository and creating a local copy:

git clone https://github.com/YOURACCOUNT/xarray-tutorial.git
cd xarray-tutorial

Create a Python environment

You'll need conda or mamba, which can be installed from https://github.com/conda-forge/miniforge

We also use conda-lock to ensure we have reproducible environments across different operating systems

We also use pre-commit hooks to run styling and other checks before committing code.

conda-lock install -f conda/conda-lock.yml
# Or latest package versions: `mamba env create -f conda/environment-unpinned.yml`

conda activate xarray-tutorial

pre-commit install

Develop your new content on a branch. See JupyterBook Docs for guides on adding .md, .ipynb and other content.

git checkout -b newcontent
git add .
git commit -m "added pages x,y and improved z"
