Just add the following code to your HTML or WordPress widget:

<center><iframe style="border: 0; width: 100%; height: 700px;" src="https://chat2.cyirc.org/#yourchannel" width="100%" height="700"></iframe></center>

#yourchannel should be replaced with the channel name you have registered on the network. If you haven’t done so, register it on the IRC network and then come here again. Arrange the size of your liking. You can also use the linking of a channel by using https://chat.cyirc.org/#yourchannel on any web browser.
