+      PoMiDAQ is a recording software for UCLA Miniscopes for neuroscientific research.
+      It is designed to work with the latest OpenCV libraries and provides a shared library,
+      so Miniscope recording features can easily be embedded into other programs and pipelines.
+    </p>
+    <p>
+      Recorded data is encoded with the FFV1 codec by default, to allow for smaller, lossless video files that are safe to archive.
