Make sure that your submission has the following:

• A link to the raw github markdown file with a YAML front matter definition containing:
  • The title of your extension
  • A description of your extension
  • The author
  • A hero image
  • An icon

Please, go through these steps before you submit a PR.

• You have done your changes in a separate branch.

• You have a descriptive commit message with a short title (first line).

• You have only one commit (if not, squash them into one commit).

Hi @CelesteBloodreign

We have a migration taking place to move our domain from owlbear.app to owlbear.rodeo.

If you rely on a CORS Access-Control-Allow-Origin policy then please change this to either * or https://www.owlbear.rodeo.

Apologies for the late notice and we'll do our best to inform you once migration is complete.
