<h1>Platform Introduction<a class="headerlink" href="#platform-introduction" title="Permalink to this headline">#</a></h1>
<p>The GNOME platform consists of libraries, services and tools which provide everything you need to create and distribute high-quality apps. The platform covers everything from basic UI creation, code editing and building, and app distribution, through to more specialised libraries and services.</p>
<p>This introduction provides an overview of the GNOME platform. It is great way to get started for those who are new to the GNOME platform, as well as being a valuable reference for those who are looking for particular specialist functionality.</p>
<p>The platform introduction is composed of the following sections:</p>
<ul class="simple">
<li><p><a class="reference internal" href="introduction/components.html"><span class="doc">Components</span></a>: an overview of GNOME platform libraries and services</p></li>
<li><p><a class="reference internal" href="introduction/languages.html"><span class="doc">Languages</span></a>: information on the programming languages that can be used with the GNOME platform</p></li>
<li><p><a class="reference internal" href="introduction/builder.html"><span class="doc">Builder</span></a>: an introduction to Builder, the GNOME IDE</p></li>
<li><p><a class="reference internal" href="introduction/flatpak.html"><span class="doc">Flatpak</span></a>: an introduction to Flatpak, GNOMEs preferred app distribution technology</p></li>
