 ## Videos
 
+### Video Sharing Platform
+
 You can embed a video with the following syntax:
 
 ```liquid
 {% include embed/{Platform}.html id='{ID}' %}
 ```
+
 Where `Platform` is the lowercase of the platform name, and `ID` is the video ID.
 
 The following table shows how to get the two parameters we need in a given video URL, and you can also know the currently supported video platforms.

+### 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
+- `types` - specify the extensions of additional video formats separated by `|`. Ensure these files exist in the same directory as your primary video file.
+
+Consider an example utilizing all of the above:
+
+```liquid
+{%
+  include embed/video.html
+  src='/path/to/video/video.mp4'
+  types='ogg|mov'
+  poster='poster.png'
+  title='Demo video'
+  autoplay=true
+  loop=true
+  muted=true
+%}
+```
+
+> It's not recommended to host video files in `assets` folder as they cannot be cached by PWA and may cause issues.
+> Instead, use CDN to host video files. Alternatively, use a separate folder that is excluded from PWA (see `pwa.deny_paths` setting in `_config.yml`).
