So you've never used IRC before, and now you need to learn. This guide will walk you through the process of installing and configuring the necessary software to get you into #janiteam.
First, download and install OpenSSL:

You need this piece of software as #janiteam requires that you be connected to the Rizon network using a secure connection. If you aren't, then you can't join.
Next, install HexChat.

Just use the default options to install, and run HexChat when finished.
