    instructions = f"""
    We've edited the necessary files to require Glean SDK {version}.

    To ensure Glean and Firefox's other Rust dependencies are appropriately vendored,
    please run the following commands:

        cargo update -p glean
        ./mach vendor rust --ignore-modified

    `./mach vendor rust` may identify version mismatches.
    Please consult the Updating the Glean SDK docs for assistance:
    https://firefox-source-docs.mozilla.org/toolkit/components/glean/dev/updating_sdk.html

    The Glean SDK is already vetted and no additional vetting for it is necessary.
    To prune the configuration file after vendoring run:

        ./mach cargo vet prune

    Then, to update webrender which independently relies on the Glean SDK, run:

        cd gfx/wr
        cargo update -p glean

    Then, to ensure all is well, build Firefox and run the FOG tests.
    Instructions can be found here:
    https://firefox-source-docs.mozilla.org/toolkit/components/glean/dev/testing.html
