Hi all,

I want to distribute an AppImage that supports custom url protocols (e.g. `skype://`), so that the app automatically opens when user clicks the corresponding link. Usually this is done by adding a `MimeType` field to the `.Desktop` file and adding the custom protocol to the list of known protocols with `xdg-mime`.

The first task is easy, as the `.Desktop` file is shipped within the AppImage. However, I’m not sure at which stage I should run `xdg-mime`. I’m pretty sure the `appimaged` daemon is involved here, but how?

Hi @monocausal, welcome to AppImage.

If your user wants to have AppImages integrated into the system and hence is runnning `appimaged` (or another such tool), then your MIME type _should_ automatically be associated to your application if you put it into its `.desktop` file.

If that is not happening, please file a ticket in the project that does the desktop integration (e.g., [appimaged](https://github.com/AppImage/appimaged/issues)), along with a link to an example AppImage so that we can see what is going on. Thanks!
