+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+
+LPPL Version 1.3c 2008-05-04
+
+Copyright 1999 2002-2008 LaTeX3 Project
+ Everyone is allowed to distribute verbatim copies of this
+ license document, but modification of it is not allowed.
+
+
+PREAMBLE
+========
+
+The LaTeX Project Public License (LPPL) is the primary license under
+which the LaTeX kernel and the base LaTeX packages are distributed.
+
+You may use this license for any work of which you hold the copyright
+and which you wish to distribute. This license may be particularly
+suitable if your work is TeX-related (such as a LaTeX package), but
+it is written in such a way that you can use it even if your work is
+unrelated to TeX.
+
+The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE',
+below, gives instructions, examples, and recommendations for authors
+who are considering distributing their works under this license.
+
+This license gives conditions under which a work may be distributed
+and modified, as well as conditions under which modified versions of
+that work may be distributed.
+
+We, the LaTeX3 Project, believe that the conditions below give you
+the freedom to make and distribute modified versions of your work
+that conform with whatever technical specifications you wish while
+maintaining the availability, integrity, and reliability of
+that work. If you do not see how to achieve your goal while
+meeting these conditions, then read the document `cfgguide.tex'
+and `modguide.tex' in the base LaTeX distribution for suggestions.
+
+
+DEFINITIONS
+===========
+
+In this license document the following terms are used:
+
+ `Work'
+ Any work being distributed under this License.
+
+ `Derived Work'
+ Any work that under any applicable law is derived from the Work.
+
+ `Modification'
+ Any procedure that produces a Derived Work under any applicable
+ law -- for example, the production of a file containing an
+ original file associated with the Work or a significant portion of
+ such a file, either verbatim or with modifications and/or
+ translated into another language.
+
+ `Modify'
+ To apply any procedure that produces a Derived Work under any
+ applicable law.
+
+ `Distribution'
+ Making copies of the Work available from one person to another, in
+ whole or in part. Distribution includes (but is not limited to)
+ making any electronic components of the Work accessible by
+ file transfer protocols such as FTP or HTTP or by shared file
+ systems such as Sun's Network File System (NFS).
+
+ `Compiled Work'
+ A version of the Work that has been processed into a form where it
+ is directly usable on a computer system. This processing may
+ include using installation facilities provided by the Work,
+ transformations of the Work, copying of components of the Work, or
+ other activities. Note that modification of any installation
+ facilities provided by the Work constitutes modification of the Work.
+
+ `Current Maintainer'
+ A person or persons nominated as such within the Work. If there is
+ no such explicit nomination then it is the `Copyright Holder' under
+ any applicable law.
+
+ `Base Interpreter'
+ A program or process that is normally needed for running or
+ interpreting a part or the whole of the Work.
+
+ A Base Interpreter may depend on external components but these
+ are not considered part of the Base Interpreter provided that each
+ external component clearly identifies itself whenever it is used
+ interactively. Unless explicitly specified when applying the
+ license to the Work, the only applicable Base Interpreter is a
+ `LaTeX-Format' or in the case of files belonging to the
+ `LaTeX-format' a program implementing the `TeX language'.
+
+
+
+CONDITIONS ON DISTRIBUTION AND MODIFICATION
+===========================================
+
+1. Activities other than distribution and/or modification of the Work
+are not covered by this license; they are outside its scope. In
+particular, the act of running the Work is not restricted and no
+requirements are made concerning any offers of support for the Work.
+
+2. You may distribute a complete, unmodified copy of the Work as you
+received it. Distribution of only part of the Work is considered
+modification of the Work, and no right to distribute such a Derived
+Work may be assumed under the terms of this clause.
+
+3. You may distribute a Compiled Work that has been generated from a
+complete, unmodified copy of the Work as distributed under Clause 2
+above, as long as that Compiled Work is distributed in such a way that
+the recipients may install the Compiled Work on their system exactly
+as it would have been installed if they generated a Compiled Work
+directly from the Work.
+
+4. If you are the Current Maintainer of the Work, you may, without
+restriction, modify the Work, thus creating a Derived Work. You may
+also distribute the Derived Work without restriction, including
+Compiled Works generated from the Derived Work. Derived Works
+distributed in this manner by the Current Maintainer are considered to
+be updated versions of the Work.
+
+5. If you are not the Current Maintainer of the Work, you may modify
+your copy of the Work, thus creating a Derived Work based on the Work,
+and compile this Derived Work, thus creating a Compiled Work based on
+the Derived Work.
+
+6. If you are not the Current Maintainer of the Work, you may
+distribute a Derived Work provided the following conditions are met
+for every component of the Work unless that component clearly states
+in the copyright notice that it is exempt from that condition. Only
+the Current Maintainer is allowed to add such statements of exemption
+to a component of the Work.
+
+ a. If a component of this Derived Work can be a direct replacement
+ for a component of the Work when that component is used with the
+ Base Interpreter, then, wherever this component of the Work
+ identifies itself to the user when used interactively with that
+ Base Interpreter, the replacement component of this Derived Work
+ clearly and unambiguously identifies itself as a modified version
+ of this component to the user when used interactively with that
+ Base Interpreter.
+
+ b. Every component of the Derived Work contains prominent notices
+ detailing the nature of the changes to that component, or a
+ prominent reference to another file that is distributed as part
+ of the Derived Work and that contains a complete and accurate log
+ of the changes.
+
+ c. No information in the Derived Work implies that any persons,
+ including (but not limited to) the authors of the original version
+ of the Work, provide any support, including (but not limited to)
+ the reporting and handling of errors, to recipients of the
+ Derived Work unless those persons have stated explicitly that
+ they do provide such support for the Derived Work.
+
+ d. You distribute at least one of the following with the Derived Work:
+
+ 1. A complete, unmodified copy of the Work;
+ if your distribution of a modified component is made by
+ offering access to copy the modified component from a
+ designated place, then offering equivalent access to copy
+ the Work from the same or some similar place meets this
+ condition, even though third parties are not compelled to
+ copy the Work along with the modified component;
+
+ 2. Information that is sufficient to obtain a complete,
+ unmodified copy of the Work.
+
+7. If you are not the Current Maintainer of the Work, you may
+distribute a Compiled Work generated from a Derived Work, as long as
+the Derived Work is distributed to all recipients of the Compiled
+Work, and as long as the conditions of Clause 6, above, are met with
+regard to the Derived Work.
+
+8. The conditions above are not intended to prohibit, and hence do not
+apply to, the modification, by any method, of any component so that it
+becomes identical to an updated version of that component of the Work as
+it is distributed by the Current Maintainer under Clause 4, above.
+
+9. Distribution of the Work or any Derived Work in an alternative
+format, where the Work or that Derived Work (in whole or in part) is
+then produced by applying some process to that format, does not relax or
+nullify any sections of this license as they pertain to the results of
+applying that process.
+
+10. a. A Derived Work may be distributed under a different license
+ provided that license itself honors the conditions listed in
+ Clause 6 above, in regard to the Work, though it does not have
+ to honor the rest of the conditions in this license.
+
+ b. If a Derived Work is distributed under a different license, that
+ Derived Work must provide sufficient documentation as part of
+ itself to allow each recipient of that Derived Work to honor the
+ restrictions in Clause 6 above, concerning changes from the Work.
+
+11. This license places no restrictions on works that are unrelated to
+the Work, nor does this license place any restrictions on aggregating
+such works with the Work by any means.
+
+12. Nothing in this license is intended to, or may be used to, prevent
+complete compliance by all parties with all applicable laws.
+
+
+NO WARRANTY
+===========
+
+There is no warranty for the Work. Except when otherwise stated in
+writing, the Copyright Holder provides the Work `as is', without
+warranty of any kind, either expressed or implied, including, but not
+limited to, the implied warranties of merchantability and fitness for a
+particular purpose. The entire risk as to the quality and performance
+of the Work is with you. Should the Work prove defective, you assume
+the cost of all necessary servicing, repair, or correction.
+
+In no event unless required by applicable law or agreed to in writing
+will The Copyright Holder, or any author named in the components of the
+Work, or any other party who may distribute and/or modify the Work as
+permitted above, be liable to you for damages, including any general,
+special, incidental or consequential damages arising out of any use of
+the Work or out of inability to use the Work (including, but not limited
+to, loss of data, data being rendered inaccurate, or losses sustained by
+anyone as a result of any failure of the Work to operate with any other
+programs), even if the Copyright Holder or said author or said other
+party has been advised of the possibility of such damages.
+
+
+MAINTENANCE OF THE WORK
+=======================
+
+The Work has the status `author-maintained' if the Copyright Holder
+explicitly and prominently states near the primary copyright notice in
+the Work that the Work can only be maintained by the Copyright Holder
+or simply that it is `author-maintained'.
+
+The Work has the status `maintained' if there is a Current Maintainer
+who has indicated in the Work that they are willing to receive error
+reports for the Work (for example, by supplying a valid e-mail
+address). It is not required for the Current Maintainer to acknowledge
+or act upon these error reports.
+
+The Work changes from status `maintained' to `unmaintained' if there
+is no Current Maintainer, or the person stated to be Current
+Maintainer of the work cannot be reached through the indicated means
+of communication for a period of six months, and there are no other
+significant signs of active maintenance.
+
+You can become the Current Maintainer of the Work by agreement with
+any existing Current Maintainer to take over this role.
+
+If the Work is unmaintained, you can become the Current Maintainer of
+the Work through the following steps:
+
+ 1. Make a reasonable attempt to trace the Current Maintainer (and
+ the Copyright Holder, if the two differ) through the means of
+ an Internet or similar search.
+
+ 2. If this search is successful, then enquire whether the Work
+ is still maintained.
+
+ a. If it is being maintained, then ask the Current Maintainer
+ to update their communication data within one month.
+
+ b. If the search is unsuccessful or no action to resume active
+ maintenance is taken by the Current Maintainer, then announce
+ within the pertinent community your intention to take over
+ maintenance. (If the Work is a LaTeX work, this could be
+ done, for example, by posting to comp.text.tex.)
+
+ 3a. If the Current Maintainer is reachable and agrees to pass
+ maintenance of the Work to you, then this takes effect
+ immediately upon announcement.
+
+ b. If the Current Maintainer is not reachable and the Copyright
+ Holder agrees that maintenance of the Work be passed to you,
+ then this takes effect immediately upon announcement.
+
+ 4. If you make an `intention announcement' as described in 2b. above
+ and after three months your intention is challenged neither by
+ the Current Maintainer nor by the Copyright Holder nor by other
+ people, then you may arrange for the Work to be changed so as
+ to name you as the (new) Current Maintainer.
+
+ 5. If the previously unreachable Current Maintainer becomes
+ reachable once more within three months of a change completed
+ under the terms of 3b) or 4), then that Current Maintainer must
+ become or remain the Current Maintainer upon request provided
+ they then update their communication data within one month.
+
+A change in the Current Maintainer does not, of itself, alter the fact
+that the Work is distributed under the LPPL license.
+
+If you become the Current Maintainer of the Work, you should
+immediately provide, within the Work, a prominent and unambiguous
+statement of your status as Current Maintainer. You should also
+announce your new status to the same pertinent community as
+in 2b) above.
+
+
+WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
+======================================================
+
+This section contains important instructions, examples, and
+recommendations for authors who are considering distributing their
+works under this license. These authors are addressed as `you' in
+this section.
+
+Choosing This License or Another License
+----------------------------------------
+
+If for any part of your work you want or need to use *distribution*
+conditions that differ significantly from those in this license, then
+do not refer to this license anywhere in your work but, instead,
+distribute your work under a different license. You may use the text
+of this license as a model for your own license, but your license
+should not refer to the LPPL or otherwise give the impression that
+your work is distributed under the LPPL.
+
+The document `modguide.tex' in the base LaTeX distribution explains
+the motivation behind the conditions of this license. It explains,
+for example, why distributing LaTeX under the GNU General Public
+License (GPL) was considered inappropriate. Even if your work is
+unrelated to LaTeX, the discussion in `modguide.tex' may still be
+relevant, and authors intending to distribute their works under any
+license are encouraged to read it.
+
+A Recommendation on Modification Without Distribution
+-----------------------------------------------------
+
+It is wise never to modify a component of the Work, even for your own
+personal use, without also meeting the above conditions for
+distributing the modified component. While you might intend that such
+modifications will never be distributed, often this will happen by
+accident -- you may forget that you have modified that component; or
+it may not occur to you when allowing others to access the modified
+version that you are thus distributing it and violating the conditions
+of this license in ways that could have legal implications and, worse,
+cause problems for the community. It is therefore usually in your
+best interest to keep your copy of the Work identical with the public
+one. Many works provide ways to control the behavior of that work
+without altering any of its licensed components.
+
+How to Use This License
+-----------------------
+
+To use this license, place in each of the components of your work both
+an explicit copyright notice including your name and the year the work
+was authored and/or last substantially modified. Include also a
+statement that the distribution and/or modification of that
+component is constrained by the conditions in this license.
+
+Here is an example of such a notice and statement:
+
+ %% pig.dtx
+ %% Copyright 2005 M. Y. Name
+ %
+ % This work may be distributed and/or modified under the
+ % conditions of the LaTeX Project Public License, either version 1.3
+ % of this license or (at your option) any later version.
+ % The latest version of this license is in
+ % http://www.latex-project.org/lppl.txt
+ % and version 1.3 or later is part of all distributions of LaTeX
+ % version 2005/12/01 or later.
+ %
+ % This work has the LPPL maintenance status `maintained'.
+ %
+ % The Current Maintainer of this work is M. Y. Name.
+ %
+ % This work consists of the files pig.dtx and pig.ins
+ % and the derived file pig.sty.
+
+Given such a notice and statement in a file, the conditions
+given in this license document would apply, with the `Work' referring
+to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being
+generated from `pig.dtx' using `pig.ins'), the `Base Interpreter'
+referring to any `LaTeX-Format', and both `Copyright Holder' and
+`Current Maintainer' referring to the person `M. Y. Name'.
+
+If you do not want the Maintenance section of LPPL to apply to your
+Work, change `maintained' above into `author-maintained'.
+However, we recommend that you use `maintained', as the Maintenance
+section was added in order to ensure that your Work remains useful to
+the community even when you can no longer maintain and support it
+yourself.
+
+Derived Works That Are Not Replacements
+---------------------------------------
+
+Several clauses of the LPPL specify means to provide reliability and
+stability for the user community. They therefore concern themselves
+with the case that a Derived Work is intended to be used as a
+(compatible or incompatible) replacement of the original Work. If
+this is not the case (e.g., if a few lines of code are reused for a
+completely different task), then clauses 6b and 6d shall not apply.
+
+
+Important Recommendations
+-------------------------
+
+ Defining What Constitutes the Work
+
+ The LPPL requires that distributions of the Work contain all the
+ files of the Work. It is therefore important that you provide a
+ way for the licensee to determine which files constitute the Work.
+ This could, for example, be achieved by explicitly listing all the
+ files of the Work near the copyright notice of each file or by
+ using a line such as:
+
+ % This work consists of all files listed in manifest.txt.
+
+ in that place. In the absence of an unequivocal list it might be
+ impossible for the licensee to determine what is considered by you
+ to comprise the Work and, in such a case, the licensee would be
+ entitled to make reasonable conjectures as to which files comprise
+ the Work.
+

+
+# `cleveref-forward` — Forward-referencing functionality for cleveref
+
+`cleveref-forward` aims at providing the forward-referencing functionality to `cleveref`.
+
+This package is derived from the package [`cleveref-usedon`](https://ctan.org/pkg/cleveref-usedon), with several fixes and enhancements.
+
+## Regarding the usage
+
+It might be a good idea to start with the [demo documents](https://github.com/Jinwen-XU/cleveref-forward/tree/main/demo).
+
+> The documentation and examples written by Sven Pistre for the original package [`cleveref-usedon`](https://ctan.org/pkg/cleveref-usedon) are also very inspiring (but be aware that the usage has changed a lot, so some of the code there may no longer work here).
+
+## Known issues / what to do next
+
+- The multilingual support is not yet perfect.
+- The code is somewhat messy for now, and the naming of many macros should be made better.
+- The support for displayed maths is still not perfect.
+- Not all configuration yields nice result, more examples are needed.
+
+The original package [`cleveref-usedon`](https://ctan.org/pkg/cleveref-usedon) is better in terms of documentation, while the current package is slightly more advanced in terms of code. It is hoped that one day they can be combined into a better version.
+
+
+## Acknowledgement
+
+The author would like to thank:
+
+- Sven Pistre, for originally developing the nice package [`cleveref-usedon`](https://ctan.org/pkg/cleveref-usedon), and for the friendly discussions with him that inspired many of the modifications later.
+- Ulrich Diez, for his help in a key step of the new configuration command.

+ Some proof that involves the \cref[used by]{lem:result} and the equations \labelcref[used by and on]{eq:Euler}, \labelcref[used by]{eq:1,eq:2} in the next section. Here, \lstinline|\restorelabel| makes sure that this \texttt{proof} environment is being recognized as the theorem itself.
+\end{proof}
+
+\subsection{Equations}
+
+By default, the forward referencing infomation is placed immediately after the equation.
+
+\begin{equation}\label{eq:Euler}
+ \mathrm{e}^{\mathrm{i}\pi} + 1 = 0.
+\end{equation}
+
+However, with this method, for multilined equations with multiple references, only the last reference will be shown:
+\begin{align}
+ 1 &= 0 + 1 \label{eq:1}\\
+ 2 &= 1 + 1 \label{eq:2}
+\end{align}
+
+This can be overcome if you are willing to place the text message in the margin, see the section on customization.
+
+\subsection{Other types}
+
+It can also be used for some other types, such as items in \texttt{enumerate} list, as long as \textsf{cleveref} is properly configured for that type.
+
+\section{Specify a default option}
+
+If you wish to apply the mode \commandoption{used on}, or \commandoption{used by}, or \commandoption{used by and on} to all \lstinline|\cref| (and \lstinline|\labelcref|, etc.), you can use the package option \packageoption{default = }\meta{mode}. Then you don't need to write it everywhere. And if you wish to manually change this \meta{mode} somewhere, you can still specify it as the command option; and if you don't want the message to display for some references, you may also use the option \commandoption{no use} on the corresponding \lstinline|\label| to disable the related messages.
+
+
+\section{Customizations}
+
+\begingroup
+
+Here is how you change the appearing text:
+
+\begin{code}
+\SetUsedOnMessageText{Appears on~#1.}
+\SetUsedByMessageText{Appears in~#1.}
+\SetUsedByAndOnMessageText{Appears in~#1 on~#2.}
+\end{code}
+
+\SetUsedOnMessageText{Appears on~#1.}
+\SetUsedByMessageText{Appears in~#1.}
+\SetUsedByAndOnMessageText{Appears in~#1 on~#2.}
+
+\bigskip
+And here is an example of setting the message style with \textsf{todonotes}:
+
+\begin{code}
+\SetForwardReferenceStyle
+ {%
+ \todo[%
+ inline,
+ size=\scriptsize,
+ color=blue!40,
+ backgroundcolor=white,
+ textcolor=blue!50!cyan,
+ bordercolor=blue!50!cyan,
+ noprepend]{%
+ \textup{#1}%
+ }%
+ }
+\SetForwardReferenceStyleOutsideMath
+ {%
+ \todo[%
+ inline,
+ size=\scriptsize,
+ caption={}, % <-- needed, otherwise there would be errors
+ color=blue!40,
+ backgroundcolor=white,
+ textcolor=blue!50!cyan,
+ bordercolor=blue!50!cyan,
+ noprepend]{%
+ \textup{#1}%
+ }%
+ }
+\end{code}
+
+\SetForwardReferenceStyle
+ {%
+ \todo[%
+ inline,
+ size=\scriptsize,
+ color=blue!40,
+ backgroundcolor=white,
+ textcolor=blue!50!cyan,
+ bordercolor=blue!50!cyan,
+ noprepend]{%
+ \textup{#1}%
+ }%
+ }
+\SetForwardReferenceStyleOutsideMath
+ {%
+ \todo[%
+ inline,
+ size=\scriptsize,
+ caption={}, % <-- needed, otherwise there would be errors
+ color=blue!40,
+ backgroundcolor=white,
+ textcolor=blue!50!cyan,
+ bordercolor=blue!50!cyan,
+ noprepend]{%
+ \textup{#1}%
+ }%
+ }
+
+\bigskip
+We use the same example:
+
+\begin{lemma}\label{lem:result'}
+ Some preliminary result (see the equation \labelcref[used by]{eq:1'}).
+\end{lemma}
+
+\begin{theorem}\label{thm:test'}
+ Text.
+\end{theorem}
+\begin{proof}\restorelabel{thm:test'} % Notice the use of \restorelabel here
+ Some proof that involves the \cref[used by]{lem:result'} and the equations \labelcref[used by and on]{eq:Euler'}, \labelcref[used by]{eq:1',eq:2'}.
+\end{proof}
+
+\begin{equation}\label{eq:Euler'}
+ \mathrm{e}^{\mathrm{i}\pi} + 1 = 0.
+\end{equation}
+\vspace{-\baselineskip}
+\begin{align}
+ 1 &= 0 + 1 \label{eq:1'}\\
+ 2 &= 1 + 1 \label{eq:2'}
+\end{align}
+
+\bigskip
+As you might have noticed, \lstinline|\SetForwardReferenceStyleOutsideMath| is for setting the style of those messages that appear outside the equations.
+
+There is also a \lstinline|\SetForwardReferenceStyleInsideMath|, which triggers the message immediately at where you placed the label. This way it is only plausible to put the message inside the margin. For example, you may configure:
+
+\begin{code}
+\SetForwardReferenceStyle
+ {%
+ \marginnote{\normalfont#1}%
+ }
+\SetForwardReferenceStyleInsideMath
+ {%
+ \marginnote{\normalfont#1}%
+ }
+\end{code}
+
+\SetForwardReferenceStyle
+ {%
+ \marginnote{\normalfont#1}%
+ }
+\SetForwardReferenceStyleInsideMath
+ {%
+ \marginnote{\normalfont#1}%
+ }
+
+\bigskip
+The result would be somewhat like the following (assuming that your document has margins set wide enough):
+
+\vspace{-\baselineskip}
+\setlength{\marginparwidth}{20em}
+\setlength{\marginparsep}{-15em}
+\begin{adjustwidth}{}{16em}
+ \begin{lemma}\label{lem:result''}
+ Some preliminary result (see the equation \labelcref[used by]{eq:1''}).
+ \end{lemma}
+
+ \begin{theorem}\label{thm:test''}
+ Text.
+ \end{theorem}
+ \begin{proof}\restorelabel{thm:test''} % Notice the use of \restorelabel here
+ Some proof that involves the \cref[used by]{lem:result''} and the equations \labelcref[used by and on]{eq:Euler''}, \labelcref[used by]{eq:1'',eq:2''}.
+ \end{proof}
+
+ \begin{equation}\label{eq:Euler''}
+ \mathrm{e}^{\mathrm{i}\pi} + 1 = 0.
+ \end{equation}
+ \begin{align}
+ 1 &= 0 + 1 \label{eq:1''}\\
+ 2 &= 1 + 1 \label{eq:2''}
+ \end{align}
+\end{adjustwidth}
+
+\bigskip
+\begin{tip}[Attention]
+ Please pay attention to the usage of \lstinline|#1| and \lstinline|#2| in the configurations.
+\end{tip}
+
+\clearpage
+By the way, here is the default setting for the style:
+
+\begin{code}
+\SetForwardReferenceStyle
+ {%
+ \emph{#1} \\[.3\baselineskip]%
+ }
+\SetForwardReferenceStyleOutsideMath
+ {%
+ \begin{flushright}%
+ \emph{#1}%
+ \end{flushright}%
+ \vspace{.15\baselineskip}%
+ }
+\end{code}
+
+\endgroup
+
+\SetForwardReferenceStyle
+ {%
+ \marginnote{\normalfont#1}%
+ }
+\SetForwardReferenceStyleInsideMath
+ {%
+ \marginnote{\normalfont#1}%
+ }
+
+%% You can safely ignore the code between \ExplSyntaxOn and \ExplSyntaxOff
+%% They are just for resetting the theorem referencing style for the rest of the document
+\ExplSyntaxOn
+\input{create-theorem-preset-names} % simple-name mode is not suitable for French, German, etc.
+\exp_args:No \SetTheorem { \c_projlib_theorem_supported_clist, theorem-with-name } % remove the text style in the references

+ }
+\ExplSyntaxOff

+\section{Besides writing in English}
+
+When writing in some European languages, it is possible to specify the definite article and/or declension in the optional argument of \lstinline|\cref| to ensure that the grammar is correct, provided that you have enabled the package option \packageoption{crefthe}.

+\subsection{Regarding the customization}
+
+If you wish to change the content of the messages in such cases, you might need to be careful about the definite article and declension involved. For example, in German, if you wish to change the text to \textquote{Erscheint in ... auf ...} (\emph{Appears in ... on ...}), you need to write:
+\begin{code}
+\SetUsedOnMessageText{Erscheint auf~#1.}
+\SetUsedByMessageText{Erscheint #1.}
+\SetUsedByAndOnMessageText{Erscheint #1 auf~#2.}
+\SetForwardReferenceRefForm{\crefthe[in,dat.]}
+\SetForwardReferencePagerefForm{\cpagerefthe[noun]}
+\end{code}
+which set the \lstinline|\cref| command to use the definite article \textquote{in} and the declension \textquote{Dativ}, and hide the definite article when using \lstinline|\cpageref|.
