 The bundled es_systems.xml file is located in the resources directory that is part of the application installation. For example this could be `/usr/share/emulationstation/resources/systems/unix/es_systems.xml` on Unix, `/Applications/EmulationStation Desktop Edition.app/Contents/Resources/resources/systems/macos/es_systems.xml` on macOS or `C:\Program Files\EmulationStation-DE\resources\systems\windows\es_systems.xml` on Windows. The actual location may differ from these examples of course, depending on where ES-DE has been installed.
 
+If you're using the AppImage release of ES-DE then the bundled es_systems.xml file is embedded in the AppImage together with the rest of the resources.

 It doesn't matter in which order you define the systems as they will be sorted by the `<fullname>` tag or by the optional `<systemsortname>` tag when displayed inside the application. But it's still a good idea to add the systems in alphabetical order to make the configuration file easier to maintain.
 
 Note that the `<systemsortname>` tags are sorted in [lexicographic order](https://en.wikipedia.org/wiki/Lexicographic_order) so 11 will be sorted above 2 but 002 will be sorted above 011.

 Although you place additional themes in your ES-DE home directory, the default slate-DE and modern-DE themes are located in the installation folder. For example this could be `/usr/share/emulationstation/themes` or `/usr/local/share/emulationstation/themes` on Unix, `/Applications/EmulationStation Desktop Edition.app/Contents/Resources/themes` on macOS or `C:\Program Files\EmulationStation-DE\themes` on Windows.
 
+Note that if using the AppImage release on Linux, then there is no installation folder as all files are contained inside the AppImage file.

 So if you would like to customize the slate-DE or modern-DE theme sets, simply make a copy of their directories to ~/.emulationstation/themes and then those copies will take precedence over the ones in the application installation directory.
 
 Here is a good resource with a list of themes (although you will have to search online for the download location for each theme set):
