You must have a client IRC program called mIRC or one similar. To Get mIRC go to http://www.mirc.com. You can download it for free.
Then start mIRC, and when you are at the mIRC Options window, fill out the lower section and then select a Dalnet server from the list of servers in that window. Click "Connect to IRC Server" button and after you have connected, another small window will open. It is called the "Channels Folder" window. Click the ADD button on the right, and add #healingroom. Then click Join button and you are with us!
