1. Ensure your DOCTYPE declaration is set to HTML5: "<!DOCTYPE html>"
2. Use the <object> tag to embed Flash content.
3. To specify that the object is Flash content, define its type using "type='application/x-shockwave-flash'"
4. Define the source of the Flash content by typing "data='Flash.swf'"
5. Other properties of the Flash content can be styled as well, such as width, height, and border
6. Close the object tag using </object>
7. Create a parameter defining the movie by typing <param name="movie". Set the value to the URL of your Flash content by typing value="Flash.swf". Close the tag the same way an <img> tag is close, by typing /> (there is no specific closing tag). Place this <param> tag before the closing </object> tag
8. Optional: Create a parameter defining the playback quality by typing <param name="quality". Set the value of the playback quality by typing value="" and placing either low, medium, or high within the quotation marks. Close the tag the same way an <img> tag is close, by typing /> (there is no specific closing tag). Place this <param> tag before the closing </object> tag
