+### Video File
+
+If you want to embed a video file directly, use the following syntax:
+
+```liquid
+{% include embed/video.html src='{URL}' %}
+```
+
+Where `URL` is an URL to a video file e.g. `/assets/img/sample/video.mp4`.
+
+You can also specify additional attributes for the embedded video file. Here is a full list of attributes allowed.
+
+- `poster='/path/to/poster.png'` - poster image for a video that is shown while video is downloading
+- `title='Text'` - title for a video that appears below the video and looks same as for images
+- `autoplay=true` - video automatically begins to play back as soon as it can
+- `loop=true` - automatically seek back to the start upon reaching the end of the video
+- `muted=true` - audio will be initially silenced
+
+Consider an example utilizing all of the above:
+
+```liquid
+{% include embed/video.html src='video.mp4' poster='poster.png' title='Demo video'
+   autoplay=true loop=true muted=true %}
+```
