+      <title>Methods</title>
+
+      <para><function>GetImage()</function> may be used to get the image object path of the image with the
+      specified name.</para>
+
+      <para><function>ListImages()</function> returns an array of all currently known images. The
+      structures in the array consist of the following fields: image name, type, read-only flag, creation
+      time, modification time, current disk space, usage and image object path.</para>
+
+      <para><function>GetImageOSRelease()</function> retrieves the OS release information of an image.
+      This method returns an array of key value pairs read from the
+      <citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry> file in
+      the image and is useful to identify the operating system used in a portable service.</para>
+
+      <para><function>GetImageMetadata()</function> retrieves metadata associated with an image.
+      This method returns the image name, the image's <citerefentry><refentrytitle>os-release</refentrytitle>
+      <manvolnum>5</manvolnum></citerefentry> content in the form of a (streamable) array of bytes,
+      and a list of portable units contained in the image, in the form of a string (unit name) and
+      an array of bytes with the content.</para>
+
+      <para><function>GetImageMetadataWithExtensions()</function> retrieves metadata associated with an
+      image. This method is a superset of <function>GetImageMetadata()</function> with the addition of a list
+      of extensions as input parameter, which were overlaid on top of the main image via
+      <function>AttachImageWithExtensions()</function>. The path of each extension and an array of bytes with
+      the content of the respective extension-release file are returned, one such structure for each
+      extension named in the input arguments.</para>
+
+      <para><function>GetImageState()</function> retrieves the image state as one of the following
+      strings:
+      <itemizedlist>
+        <listitem><para>detached</para></listitem>
+
+        <listitem><para>attached</para></listitem>
+
+        <listitem><para>attached-runtime</para></listitem>
+
+        <listitem><para>enabled</para></listitem>
+
+        <listitem><para>enabled-runtime</para></listitem>
+
+        <listitem><para>running</para></listitem>
+
+        <listitem><para>running-runtime</para></listitem>
+      </itemizedlist></para>
+
+      <para><function>GetImageStateWithExtensions()</function> is a superset of
+      <function>GetImageState()</function>, with additional support for a list of extensions
+      as input parameters, which is necessary to query the state in case the image was attached
+      in that particular way. The <varname>flag</varname> parameter is currently unused and
+      reserved for future purposes.</para>
+
+      <para><function>AttachImage()</function> attaches a portable image to the system.
+      This method takes an image path or name, a list of strings that will be used to search for
+      unit files inside the image (partial or complete matches), a string indicating which
+      portable profile to use for the image (see <varname>Profiles</varname> property for
+      a list of available profiles), a boolean indicating whether to attach the image only
+      for the current boot session, and a string representing the preferred copy mode
+      (whether to copy the image or to just symlink it) with the following possible values:
+      <itemizedlist>
+        <listitem><para>(null)</para></listitem>
+
+        <listitem><para>copy</para></listitem>
+
+        <listitem><para>symlink</para></listitem>
+      </itemizedlist>
+      This method returns the list of changes applied to the system (for example, which unit was
+      added and is now available as a system service). Each change is represented as a triplet of
+      strings: the type of change applied, the path on which it was applied, and the source
+      (if any). The type of change applied will be one of the following possible values:
+      <itemizedlist>
+        <listitem><para>copy</para></listitem>
+
+        <listitem><para>symlink</para></listitem>
+
+        <listitem><para>write</para></listitem>
+
+        <listitem><para>mkdir</para></listitem>
+      </itemizedlist>
+      Note that an image cannot be attached if a unit that it contains is already present
+      on the system.</para>
+
+      <para><function>AttachImageWithExtensions()</function> attaches a portable image to the system.
+      This method is a superset of <function>AttachImage()</function> with the addition of
+      a list of extensions as input parameter, which will be overlaid on top of the main
+      image. When this method is used, detaching must be done by passing the same arguments via the
+      <function>DetachImageWithExtensions()</function> method. For more details on this functionality,
+      see the <varname>MountImages=</varname> entry on
+      <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+      and <citerefentry><refentrytitle>systemd-sysext</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
+      </para>
+
+      <para><function>DetachImage()</function> detaches a portable image from the system.
+      This method takes an image path or name, and a boolean indicating whether the image to
+      detach was attached only for the current boot session or persistently. This method
+      returns the list of changes applied to the system (for example, which unit was removed
+      and is no longer available as a system service). Each change is represented as a triplet of
+      strings: the type of change applied, the path on which it was applied, and the source
+      (if any). The type of change applied will be one of the following possible values:
+      <itemizedlist>
+        <listitem><para>unlink</para></listitem>
+      </itemizedlist>
+      Note that an image cannot be detached if a unit that it contains is running.</para>
+
+      <para><function>DetachImageWithExtensions()</function> detaches a portable image from the system.
+      This method is a superset of <function>DetachImage()</function> with the addition of
+      a list of extensions as input parameter, which were overlaid on top of the main
+      image via <function>AttachImageWithExtensions()</function>.
+      The <varname>flag</varname> parameter is currently unused and reserved for future purposes.</para>
+
+      <para><function>ReattachImage()</function> combines the effects of the
+      <function>AttachImage()</function> method and the <function>DetachImage()</function> method.
+      The difference is that it is allowed to reattach an image while one or more of its units
+      are running. The reattach operation will fail if no matching image is attached.
+      The input parameters match the <function>AttachImage()</function> method, and the return
+      parameters are the combination of the return parameters of the
+      <function>DetachImage()</function> method (first array, units that were removed) and the
+      <function>AttachImage()</function> method (second array, units that were updated or added).</para>
+
+      <para><function>ReattachImageWithExtensions()</function> reattaches a portable image to the system.
+      This method is a superset of <function>ReattachImage()</function> with the addition of
+      a list of extensions as input parameter, which will be overlaid on top of the main
+      image. For more details on this functionality, see the <varname>MountImages=</varname> entry on
+      <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+      and <citerefentry><refentrytitle>systemd-sysext</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
+      The <varname>flag</varname> parameter is currently unused and reserved for future purposes</para>
+
+      <para><function>RemoveImage()</function> removes the image with the specified name.</para>
+
+      <para><function>MarkImageReadOnly()</function> toggles the read-only flag of an image.</para>
+
+      <para><function>SetPoolLimit()</function> sets an overall quota limit on the pool of images.</para>
+
+      <para><function>SetImageLimit()</function> sets a per-image quota limit.</para>
+
+      <para>The <function>AttachImageWithExtensions()</function>,
+      <function>DetachImageWithExtensions()</function> and
+      <function>ReattachImageWithExtensions()</function> methods take in options as flags instead of
+      booleans to allow for extendability. <varname>SD_SYSTEMD_PORTABLE_FORCE_ATTACH</varname> will cause
+      safety checks that ensure the units are not running while the new image is attached or detached
+      to be skipped. <varname>SD_SYSTEMD_PORTABLE_FORCE_SYSEXT</varname> will cause the check that the
+      <filename>extension-release.<replaceable>NAME</replaceable></filename> file in the extension image
+      matches the image name to be skipped. They are defined as follows:</para>

+
+      <para>The following methods implement the same operation as the respective methods on the
+      <interfacename>Manager</interfacename> object (see above). However, these methods operate on the image
+      object and hence does not take an image name parameter. Invoking the methods directly on the Manager
+      object has the advantage of not requiring a <function>GetImage()</function> call to get the image object
+      for a specific image name. Calling the methods on the Manager object is hence a round trip
+      optimization. List of methods:
