# Pythia Foundations Contributor's Guide

```{note}

General information on how to contribute to any Project Pythia repository
may be found [here][pythia contributor's guide].

This page will eventually contain a full guide to contributing to Project Pythia. As GitHub Pull Requests are an important part of contributing to Pythia, this guide will cross-reference tutorials on GitHub and Pull Requests.

If you need to comment on anything in Pythia Foundations you feel needs work, you can use the "open issue" or "suggest edit" buttons at the top of any Pythia Foundations page. These buttons appear when you hover over the GitHub Octocat logo. Clicking on these buttons will take you to the relevant page on GitHub, where the entirety of the Pythia Foundations material is hosted. In order to actually suggest changes, you must have a free GitHub account, as listed in the GitHub section of Pythia Foundations. This contributor's guide is strictly for Pythia Foundations; for general Project Pythia contribution guidelines, see the main [Project Pythia Contributor's Guide][pythia contributor's guide].

To quickly provide feedback about minor issues without the use of GitHub, you can also use this [Google Form](https://docs.google.com/forms/d/e/1FAIpQLSeVa1TC9xM-dk7qIE2e8bsgSrIP82yYDNw3wew3J46eREJa4w/viewform?usp=sf_link).

## Contributing a new Jupyter Notebook

If you'd like to contribute a Jupyter Notebook to these materials, please reference our [template](template) viewable on the next page. This template is available to you in `appendix/template.ipynb` if you've cloned the [source repository](https://github.com/ProjectPythia/pythia-foundations), or available as a download [directly from GitHub](https://github.com/ProjectPythia/pythia-foundations/raw/main/appendix/template.ipynb).

## Building the site

### Create a conda environment

The first time you check out this repository, run:

```bash
conda env update -f environment.yml
```

This will create or update the dev environment (`pythia-book-dev`).

### Install `pre-commit` hooks

This repository includes `pre-commit` hooks (defined in `.pre-commit-config.yaml`). To activate/install these pre-commit hooks, run:

```bash
conda activate pythia-book-dev
pre-commit install
```

This is also a one-time step.

_NOTE_: The `pre-commit` package is already installed via the `pythia-book-dev` conda environment.

### Building the book locally

To build the book locally, run the following:

```bash
conda activate pythia-book-dev
jupyter-book build .
```

Finally, you can view the book by opening the file `_build/html/index.html` with your favorite web browser. On most platforms you can simply run:

```bash
open _build/html/index.html
```

### Keeping your dev environment up to date

It's good practice to update the packages in your `pythia-book-dev` conda environment frequently to their latest versions, especially if it's been a while since you used it. If the `jupyter-book build .` command above generates error messages, that is a good indication that your conda environment may be out of date.

To update all packages in the currently activated environment to their latest versions, do this:

```bash
conda update --all
```
