If you don't already have LimeChat installed, you can download it from the App Store or visit the LimeChat website to download and install the software.

When you open LimeChat the first time it starts a connection wizard. You can skip it and add a new connection from Server / Add Server... menu in the OS X status bar.

Enter the following settings:

• Settings

  Organization:
• Network name: Your organization name
• Server: <orgname>.irc.grove.io
• Port: 6667 (for SSL use 6697)
• Server password: Your organization name (not your password)
• Nickname: Your username
• Nickserv Password: Your password

After creating a new server, LimeChat should connect and join channels automatically.

If you're not connected, right click on the server name and select Connect or select Server / Connect from the OS X status bar.

To join a channel manually, got to the Channels / Add Channel... menu in the OS X status bar. Available channels are listed on your dashboard.
