> For the complete documentation index, see [llms.txt](https://foe-helper.gitbook.io/docs/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://foe-helper.gitbook.io/docs/english/guide/documentation.md).

# Writing documentation

Structure of a docu and its code

## Create the file

Create a new empty `README.md` file in a folder named after a module of the helper. As an example, you can look at the directory `/de/erweiterung/kostenrechner`. There is also a hidden picture folder. Screenshots of the cost calculator will be placed there.

{% hint style="info" %}
A `README.md` will not appear in the URL, it will be treated as an index.\*. If it is necessary to divide a module into several pages, use unique lower case names without special characters or spaces.
{% endhint %}

This file/path must then be added to the `/SUMMARY.md` in the root directory.

```markdown
* [Helping out](english/guide/README.md)
  * [Github](english/guide/github.md)
  * [Markdown](english/guide/markdown.md)
  * [Write a docu](english/guide/documentation.md)
```

Gitbook then renders the correct structure from this and automatically generates the links.

## Structure

The subtitle of the page itself always appears at the top. Here is the title of this page

```markdown
---
description: Structure of a docu and its code
---
```

Only then comes the first headline:

```markdown
# Documentation
```

From here on, you can simply write.
