    # Mattermost Desktop is using simple-spellchecker which prevents to bind on
    # the system Arch Linux hunspell dictionnaries. This is due to the fact
    # simple-spellchecker comes with its own set of dictionnaries. They differ
    # from the hunspell dictionnaries in the sense of, hunspell's dictionnaries
    # have additional pieces of info attributed to each line.
    # e.g. in /usr/share/hunspell/fr_FR.dic, "ordinateur" (computer in English)
    # ordinateur/S*() po:nom is:mas
    # simple-spellcheck expects a line with:
    # ordinateur
    # instead
    #
    # Asking upstream to switch to electron-spellchecker will fix the issue.

    # Install dependencies should be in prepare(), that way we don't need an
