        This website is built by the Chum Web Generator <a href="{{config.source_code_url}}">(view source repository)</a>.

    <h2>SailfishOS:Chum</h2>
    <p>
        The SailfishOS:Chum community repository provides a collection of applications, tools and libraries for the
        mobile operating system <a href="https://sailfishos.org/">Sailfish&nbsp;OS</a>, compiled for
        various hardware architectures and OS release versions.
    </p>
    <h3>Goal</h3>
    <p>
        The ambition is to become the principal software distribution platform for Sailfish&nbsp;OS.
    </p>
    <p>
        In contrast to the software distribution model of the Jolla Store or <a href="https://openrepos.net/">OpenRepos</a>,
        to which binary packages are uploaded by developers, at SailfishOS:Chum software is compiled and packaged into
        RPMs in a reproducible manner directly from its source code. The source code used for compiling and packaging is
        submitted by developers to <abbr title="Open Build Service">OBS</abbr> (Open Build Service), which generates
        multiple RPM files for various combinations of hardware architectures and Sailfish&nbsp;OS release versions.
    </p>
    <p>
        This scheme ensures that the complete source code of all packages at SailfishOS:Chum is available and
        inspectable there, and that all packages are generated solely from this source code. Hence all software
        packages at SailfishOS:Chum are created in a transparent and fully traceable manner.
    </p>
    <p>
        By collecting software for Sailfish&nbsp;OS in a single automated build system, collaboration between developers
        through common packaging of shared libraries etc. is fostered, duplication of work for keeping these common
        packages up-to-date is eliminated, and it becomes much easier to determine which pieces of software exist and
        which are missing at the Sailfish&nbsp;OS&nbsp;OBS. Additionally this eases tracing multiple and potentially layered
        dependencies ("dependency chains") which is crucial for keeping the software supply chains of complex
        packages up-to-date.
    </p>
    <h3>Location</h3>
    <p>
        The SailfishOS:Chum repository proper is located at the
        <a href="https://build.sailfishos.org/project/show/sailfishos:chum">the Sailfish&nbsp;OS&nbsp;OBS</a> and
        <a href="https://github.com/sailfishos-chum/main">its project site is at GitHub</a>.
