  <title>Prerequisites for installing from source</title>
  <para>
   To install &repmgr; the prerequisites for compiling
   &postgres; must be installed. These are described in &postgres;'s
   documentation
   on <ulink url="https://www.postgresql.org/docs/current/static/install-requirements.html">build requirements</ulink>
   and <ulink url="https://www.postgresql.org/docs/current/static/docguide-toolsets.html">build requirements for documentation</ulink>.
  </para>

  <para>
   Most mainstream Linux distributions and other UNIX variants provide simple
   ways to install the prerequisites from packages.

      <literal>Debian</literal> and <literal>Ubuntu</literal>: First

      repository to your <filename>sources.list</filename> if you
      have not already done so. Then install the pre-requisites for
      building PostgreSQL with:

<sect2 id="installation-get-source">
  <title>Getting &repmgr; source code</title>

  <para>
   There are two ways to get the &repmgr; source code: with git, or by downloading tarballs of released versions.
  </para>

  <sect3>
   <title>Using <application>git</application> to get the &repmgr; sources</title>

   <para>
    Use <application><ulink url="https://git-scm.com">git</ulink></application> if you expect
    to update often, you want to keep track of development or if you want to contribute
    changes to &repmgr;. There is no reason <emphasis>not</emphasis> to use <application>git</application>
    if you're familiar with it.
   </para>

   <para>
    The source for &repmgr; is maintained at
    <ulink url="https://github.com/2ndQuadrant/repmgr">https://github.com/2ndQuadrant/repmgr</ulink>.
   </para>

   <para>
    There are also tags for each &repmgr; release, e.g. <filename>4.0.5</filename>.
   </para>

   <para>
    Clone the source code using <application>git</application>:
    <programlisting>
     git clone https://github.com/2ndQuadrant/repmgr</programlisting>
   </para>

   <para>
    For more information on using <application>git</application> see
    <ulink url="https://git-scm.com/">git-scm.com</ulink>.
   </para>

  </sect3>

  <sect3>
   <title>Downloading release source tarballs</title>

   <para>
    Official release source code is uploaded as tarballs to the
    &repmgr; website along with a tarball checksum and a matching GnuPG
    signature. See
    <ulink url="http://repmgr.org/">http://repmgr.org/</ulink>
    for the download information. See <xref linkend="appendix-signatures">
    for information on verifying digital signatures.
   </para>

   <para>
    You will need to download the repmgr source, e.g. <filename>repmgr-4.0.tar.gz</filename>.
    You may optionally verify the package checksums from the
    <literal>.md5</literal> files and/or verify the GnuPG signatures
    per <xref linkend="appendix-signatures">.
   </para>

   <para>
    After you unpack the source code archives using <literal>tar xf</literal>
    the installation process is the same as if you were installing from a git
    clone.
   </para>

 <sect2 id="installation-repmgr-source">
  <title>Installation of &repmgr; from source</title>
  <para>
   To installing &repmgr; from source, simply execute:

   <programlisting>
    ./configure && make install</programlisting>

   Ensure <command>pg_config</command> for the target PostgreSQL version is in
   <varname>$PATH</varname>.
  </para>
 </sect2>



 <sect2 id="installation-build-repmgr-docs">
   <title>Building &repmgr; documentation</title>
   <para>
    The &repmgr; documentation is (like the main PostgreSQL project)
    written in DocBook format. To build it locally as HTML, you'll need to
    install the required packages as described in the
    <ulink url="https://www.postgresql.org/docs/9.6/static/docguide-toolsets.html">
      PostgreSQL documentation</ulink> then execute:
   <programlisting>
    ./configure && make install-doc</programlisting>
   </para>
   <para>
     The generated HTML files will be placed in the <filename>doc/html</filename>
     subdirectory of your source tree.
   </para>

   <para>
     To build the documentation as a single HTML file, execute:
   <programlisting>
    cd doc/ && make repmgr.html</programlisting>
   </para>

   <note>
     <simpara>
       Due to changes in PostgreSQL's documentation build system from PostgreSQL 10,
       the documentation can currently only be built agains PostgreSQL 9.6 or earlier.
       This limitation will be fixed when time and resources permit.
