The simplest way to add videos to your website is via YouTube.
If you are adding a new video that is not already on YouTube, you need to signup here and follow the steps to upload a new video.
Copy the code in the address bar of the YouTube video. The code will be between the first two = signs
Here are some examples:
Using your login details, logon to the CMS at cms.mywork.com.au
Click on the Page you want to add a video to (underlined text)
Click on the YouTube icon
Paste the code into the box
You can also adjust the width and height of the video if desired
A box similar to below will appear
The video will now appear on your website (this is the default size)
