-    Screenshots
-
-      - To generate the default screenshot, run the task/take-screenshots script.
-        Make sure you add, commit, and push the generated screenshots directory
-        to GitHub before previewing your app in the elementary OS AppCenter.
-
-        (You will not be able to see your screenshots in the AppCenter preview if
-        your GitHub repository is set to private. In this case, you might be able
-        to get it to work by including the URL generated by GitHub when you go to
-        download the image from their online interface by including the gerenated
-        token. I don’t know if the token has an expiry or not.)
-
-        If you have many localisations and screenshots, it might make sense to
-        modify this script so that it saves them to a separate screenshots
-        repository so as to keep from bloating your app’s repository.
-
-        For an example of this, see Comet’s screenshots script:
-
-        https://github.com/small-tech/comet/blob/main/task/take-screenshots#L175
-
-      - To preview your app locally in the elementary OS AppCenter, run
-        the task/preview-in-appcenter script.
-
-      If you have localisations, the take-screenshots task will take localised
-      screenshots but you will have to add them manually to this file. For an
-      example of this, see Comet’s app metadata:
-
-      https://github.com/small-tech/comet/blob/main/data/comet.appdata.xml.in#L39
