Where can I find more information?

If you'd like to get more details on all aspects of the review process for open source pull requests (OSPRs), check out the following resources:

• Overview of Review Process for Community Contributions
• Pull Request Status Guide
• Making changes to your pull request

When can I expect my changes to be merged?

Our goal is to get community contributions seen and reviewed as efficiently as possible.

However, the amount of time that it takes to review and merge a PR can vary significantly based on factors such as:

• The size and impact of the changes that it introduces
• The need for product review
• Maintenance status of the parent repository

💡 As a result it may take up to several weeks or months to complete a review and merge your PR.

This looks good. However, you'll also need to regenerate the XML (see https://github.com/openedx/training-courses?tab=readme-ov-file#contributing) for that test to pass. You also need to use conventional commits.

[AntonOfTheWoods]

Ok, so going back it does look like I skipped that chapter :-D. I squashed the commits and added a fix:. From my reading of this, footers are ok, right?

[sarina]

Yep, footers work!

[sarina]

Hmm, so, the tests didn't fail but also you didn't touch the other two courses so I'm not sure why there are changes to those .tar.gz files ,could you remove those?

[AntonOfTheWoods]

@sarina removed.

Thanks! I'll update the course with the new solutions later today.
