<h1> But what is a jabber? </h1>
<hr />
<p> <blockquote>
Extensible Messaging and Presence Protocol (<a href="https://xmpp.org">XMPP</a>, originally named <a href="https://xmpp.org">Jabber</a>) is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance.
</blockquote> </p>
<h2> What's a good client for it? </h2>
<p>
Generally speaking, Gajim is the most modern one, Dyno is the most stable one, and Conversations (or forks like Blabber.im) are the most stable and feature rich ones for Android.
</p>
<h2> How do i log in? </h2>
<p>
First, you need to <a href="/register">register</a> your account. Then you can log in with your credentials, such as username@adastra7.net (this is what is called a JID, not an email address) and your password of choice. Your client shuold automatically connect to adastra7.net at port 5222.
