    <title>Introduction to falkon</title>

    <para>
      <application>Falkon</application> is a KDE web browser using the QtWebEngine
      rendering engine. It was previously known as <application>QupZilla</application>.
      It aims to be a lightweight web browser available through all major platforms.
    </para>

    <para>
      Although <application>falkon</application> is now part of KDE, it can be
      installed without KDE (with the loss of <application>kwallet</application>
      functionality).
    </para>

    <para>
      Falkon relies on QtWebEngine. Please read the warning on that page.

        Strictly speaking, only karchive and ki18n are required to build falkon,

        used if they are present. To build only karchive and ki18n, download
        those packages from the directory specified in
        <xref linkend="kf6-frameworks"/> and use the build instructions on that
        page, changing the $KF6_PREFIX to /usr.

    <title>Installation of falkon</title>

    <para>
      Install <application>falkon</application> by running the following
      commands:
    </para>

<screen><userinput>mkdir build &amp;&amp;
cd    build &amp;&amp;

cmake -DCMAKE_INSTALL_PREFIX=/usr \
      -DCMAKE_BUILD_TYPE=Release  \
      .. &amp;&amp;

make</userinput></screen>

    <para>
      Tests should be run after installation.
    </para>

    <para>
      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>make install &amp;&amp;
ldconfig</userinput></screen>

    <para>
      To test the results, issue: <command>make test</command>. All
      tests should pass. If any fail, the full results will be in
      <filename>Testing/Temporary/LastTest.log</filename>.
    </para>

    <note>
      <para>
        When upgrading this package, it is possible that the contents
        of the application will remain empty even though everything else
        appears to be working properly.  In this case try removing
        <filename>~/.cache/falkon</filename> and restarting the program.
      </para>
    </note>

    <para>
      If you have installed <application>Pyside2</application> you will want to
      examine <command>hellopython.py</command> which is in the <filename
      class="directory">scripts/</filename> directory, and perhaps copy it to
      your home directory.
    </para>

    <note>
      <para>
        If you are on a non-x86_64 architecture and run into problems with
        missing text, you may wish to export
        <envar>QTWEBENGINE_CHROMIUM_FLAGS="--no-sandbox"</envar> prior to
        running Falkon.
