<h3>core.conf</h3>
<p>The core configuration is shared between all instances:</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>[mpd]
hostname = ::
<div class="language-conf highlighter-rouge"><pre class="highlight"><code>[<span class="n">mpd</span>]
<span class="n">hostname</span> = ::
[http]
hostname = ::
[<span class="n">http</span>]
<span class="n">hostname</span> = ::
[audio]
output = alsasink
[<span class="n">audio</span>]
<span class="n">output</span> = <span class="n">alsasink</span>
[spotify]
username = &lt;redacted&gt;
password = &lt;redacted&gt;
</pre></div>

[<span class="n">spotify</span>]
<span class="n">username</span> = &lt;<span class="n">redacted</span>&gt;
<span class="n">password</span> = &lt;<span class="n">redacted</span>&gt;
</code></pre>
</div>
<h3>local.conf</h3>
<p>Add the local configuration on computers that have local media files:</p>
<div class="highlighter-coderay"><div class="CodeRay">
<div class="code"><pre>[local]
media_dir = &lt;your/music/here&gt;
</pre></div>
</div>
<div class="language-conf highlighter-rouge"><pre class="highlight"><code>[<span class="n">local</span>]
<span class="n">media_dir</span> = &lt;<span class="n">your</span>/<span class="n">music</span>/<span class="n">here</span>&gt;
</code></pre>
</div>
<h3>snapcast.conf</h3>
<p>Finally, the Mopidy instance that connects with Snapcast needs special configuration. Run on a different port to avoid conflicts if you have a second Mopidy instance running on your computer. The audio output is sent to a named pipe - Snapcast will read from there. Note that you may have to adjust the audio output attribute depending on your system and audio sources.</p>

<h2>Configure Snapcast</h2>
<p>There are a number of snapcast configuration options, but the one relevant to Home Assistant is the client names. You can set them in the snapserver configuration file, by default located at <code>~/.config/Snapcast/settings.json</code>. Only edit this file while the <code>snapserver</code> is not running. Modify the <code>name</code> JSON value to your liking - this is how the client will be named in Home Assistant.</p>
