+      <p>Notes: You can choose which fields to write by repeating <code>-metadata field_name='Content'</code> for each desired field. Flags for commonly used fields (such as those recommended by the <a href="http://www.digitizationguidelines.gov/audio-visual/documents/Embed_Guideline_20120423.pdf">FADGI guidelines</a>) are as follows:</p>
+      <ul>

+      </ul>
+      <p>Example: <code>-metadata originator='US, UW Libraries'</code></p>
+      <p>Additionally, users should be aware that BWF metadata fields are limited by characters, with some such as OriginatorReference maxing out at 32. Specific information can be found in the <a href="https://tech.ebu.ch/docs/tech/tech3285.pdf">Broadcast Wave Format specification</a>. Additional examples of BWF metadata usage can be found in the <a href="http://www.dlib.indiana.edu/projects/sounddirections/papersPresent/sd_bp_07.pdf">Sound Directions report</a> by Indiana University and Harvard.</p>
