    # --------- FETCH --------------------------------------------------------------------------------------------------
    git fetch

    # --------- CHECKOUT -----------------------------------------------------------------------------------------------
    # ⚠️ Do not use --recurse-submodule here, submodule discrepencies will cause fatal error.
    #    See https://lore.kernel.org/git/20200501005432.h62dnpkx7feb7rto@glandium.org/T/

    # --------- RESET --------------------------------------------------------------------------------------------------
    # ✅ Forcefully resets tracked files on superproject + initialized submodules
    # ❌ Does NOT delete untracked files/directories
    # ❌ Does NOT initialize new submodules found in .gitmodules
    # ℹ️ @{u} is shorthand for "current branch from upstream"
    # ⚠️ Must run first without --recurse-submodules, or submodule discrepencies will cause fatal error.
    #    See https://lore.kernel.org/git/20200501005432.h62dnpkx7feb7rto@glandium.org/T/
    git reset --hard '@{u}'
    git reset --recurse-submodules --hard '@{u}'

    # --------- UPDATE SUBMODULES --------------------------------------------------------------------------------------
    # ✅ Initializes .git/config with new submodules found in .gitmodules
    # ✅ Updates initialized submodules to match what the superproject expects by:
    #     - cloning missing submodules
    #     - fetching missing commits in submodules
    #     - updating the working tree of the submodules
    # ❌ Does NOT delete untracked files/directories
    git submodule update --init --force --recursive --jobs 4

    # --------- DELETE UNTRACKED ---------------------------------------------------------------------------------------
    # ✅ Deletes ALL untracked files/directories on superproject + initialized submodules
    # ℹ️ -x Allow deletion of untracked files regardless of gitignore rules.
    # ℹ️ -d Allow recurse into untracked directories
    # ℹ️ -f Allows deletion of files/directories, except for directories with a .git subdirectory
    # ℹ️ -f Using this option twice allows deletion of directories with a .git subdirectory
    git clean -xdff && git submodule foreach --recursive git clean -xdff
