How to add a project as card into another project board?

I notice Github’s blog post included a screenshot of project board where each card is a project, rather than an issue or note.


How is this achieved? There seems to be no documentation about this. I tried searching 




but no projects showed up.

In the blog post, it states:

Enter the URL of any project on GitHub into the note field to create a project summary card

So if the project you’re trying to add a summary card for can be viewed at, then you can do the following:

  1. Open the project that you want to add the card to
  2. Click the + icon at the top of the column you want to add the card to
  3. Paste in the URL of the project you want to add. In this hypothetical case:
  4. Click the add card button

I hope that helps!
