 <h2 id="mastodonfediverse">Mastodon/Fediverse:</h2>
 <p>Mastodon is a Free Software to create a social media service similar to Twitter in features. Unlike twitter, mastodon is not controlled by a single company. Many people and organizations around the world run their own mastodon services which are referred to as instances and users of any of these instances can interact with users of any other instance. Additionally there are other software interoperable with mastodon and all of it together constitute the fediverse. Some other software part of the Fediverse are Pleroma, Friendica, Peertube, Pixelfed etc.</p>
 <h2 id="matrixelement">Matrix/Element:</h2>
 <p>Matrix is a communication protocol for sharing instant messages, photos, files and audio/video calls. Element is most feature-complete app for Matrix protocol and is available on smart phones and laptop/desktop. Matrix has a similar decentralized architecture to mastodon, where different people and organizations provide an interoperable network of home servers (similar to an instance of mastodon). If you are new to using matrix, you can sign up for accounts by following instructions at <a href="https://chat.feneas.org">https://chat.feneas.org</a>, <a href="https://chat.tchncs.de">https://chat.tchncs.de</a> or <a href="https://chat.privacytools.io">https://chat.privacytools.io</a>, instead of using matrix.org which will help to reduce their server load.</p>
