      <p>The Protocol Bicorder is a diagnostic tool for the study of protocols. It allows a human or machine user to evaluate protocol characteristics along a series of gradients between opposing terms.</p>
      <p>To carry out the diagnostic, consider the protocol from the perspective of one gradient at a time. Determine where the protocol lies between two terms, with <code>1</code> closest to the left-side term and closest to the term on the right. Press on the terms for brief definitions.</p>
      <p>A middle value like <code>5</code> means that the protocol reflects both terms equally. If the gradients don't seem relevant to the protocol, don't give a score or press <code>N/A</code>.</p>
      <p>Use the <code>notes</code> field to add context or explanation.</p>
      <p>Use the menu (☰) to toggle between focused/list modes and short/long forms. The default short form includes only the most salient gradients, but the long form may include important gradients for understanding the protocol at hand.</p>
      <p>At the end, you'll have the option to <code>Upload</code> your readings to an open repository, <a href="https://git.medlab.host/ntnsndr/protocol-bicorder-data" target="_blank">located here</a>.
      <p>Happy protocol watching!</p>
