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

• 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.

Hi @openedx/wg-maintainers-forums! Would someone be able to review / merge this?

[mphilbrick211]

Hi @openedx/wg-maintainers-forums! Any chance we can get this looked at? It's been stalled a bit.

This PR needs a rebase.

i disagree with this change, because rendering this as a bash codeblock erroneously highlights bash keywords. I think this README is better with generic codeblocks for the shell commands. The python and yaml blocks are a value-add.

Is this going to have an effect outside of this app? I don't think correcting typos that exist as part of method or class names is worth potential downstream breakages.
