What part(s) of the article would you like to see updated?

There is a typo re: IDs in the following:

In the following workflow, replace YOUR_ORGANIZATION with the name of your organization. For example, octo-org. Replace YOUR_PROJECT_NUMBER with your project number. To find the project number, look at the project URL. For example, https://github.com/orgs/octo-org/projects/5 has a project number of 1. In order for this specific example to work, your project must also have a "Date posted" date field.
