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
  • Tags (these will help with your extension's discoverability)
  • A link to your extensions manifest

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).

• Your pull request MUST target the main branch on this repository.

• Your pull request puts your extensions details as the last entry in the extensions.json file

Hi thanks for accepting my extension. I noticed that my assets in the referenced in markdown file wasn't showing on the extension page. I apparently by mistake used local paths as asset references in the file. This is fixed now, and the current public markdown is now using public links instead, if you at any point would like to update it:)
