            a simple and easy to use SH1MMER builder for legacy devices
        </h3>

    <div class="section blue">
        <h1> THIS IS THE LEGACY VERSION </h1>
        <h3>How to use</h3>
        <p>
            First, you'll need to find your school Chromebook's board name. This can
            be done by going to <kbd>chrome://version</kbd> on your Chromebook and
            copying the word after "stable-channel", or by looking up the chromebook's model.
        </p>
        <p>
            Next you need a raw RMA shim for that board name. There should be one corresponding to your board <a
                href="https://shim.the-repo.org/">here</a> but if not you'll have to source them on your own..
            somehow.
        </p>
        <p>
            Once you've found your raw shim, make sure to extract it if it's in a .zip file. If it has some kind of
            other compression format (.xz, .xf, .gz, etc) make sure you uncompress it first.
        </p>
        <p>
            Next, hit the big start button and select your raw .bin file. The VM will start up. This will use a
            considerable amount of memory on your system and take a while. If it freezes, that's normal. Once it
            finishes, it will automatically download the patched version.
        </p>
