# Does Overleaf support pTeX?

Yes, Overleaf can compile Japanese documents that require pTeX. Here's how:

1. A pTeX document does not need special commands for Japanese text (kanji, hiragana and katakana). Here's a simple example (using the `jsarticle` document class):

   ```latex
   \documentclass{jsarticle}

   \bibliographystyle{jplain}
   \title{p\LaTeX\ 実験}
   \author{林蓮枝}

   \begin{document}

   \maketitle

   \begin{abstract}
   本稿では、文書組版システムp\LaTeX{}の使い方を解説します。p\LaTeX{}を利用するときには、あらかじめ文章中に\TeX{}コマンドと呼ばれる組版用の指示を混在させ\ldots
   \end{abstract}

   \section{導入}
   こんにちは世界！

   \end{document}
   ```
2. If you are uploading a .tex file from elsewhere, make sure it is saved in UTF-8 encoding.
3. In the Overleaf editor, click on the Overleaf menu button above the file list panel.
4. Set the "Compiler" option to "LaTeX".
5. Add a blank file to your project, and save it as `latexmkrc`.
6. Add the following line to your `latexmkrc` file:

```
$latex = 'platex';
$bibtex = 'pbibtex';
$dvipdf = 'dvipdfmx %O -o %D %S';
```

Use the link below the following code listing to open an Overleaf project which creates a suitable `latexmkrc` file and typesets the LaTeX code.

**`main.tex`**

```latex
\documentclass{jsarticle}

\bibliographystyle{jplain}
\title{p\LaTeX\ 実験}
\author{林蓮枝}

\begin{document}

\end{abstract}

\end{document}
```

**`latexmkrc`**

```latex
$latex = 'platex';
$bibtex = 'pbibtex';
$dvipdf = 'dvipdfmx %O -o %D %S';
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/questions-and-answers/09-does-overleaf-support-ptex.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
