By default, Hugo searches for Markdown files in the `content` directory, and the structure of the directory determines the final output structure of your website.
The sidebar navigation is generated automatically based on the content organization alphabetically. To manually configure the sidebar order, we can use the `weight` parameter in the front matter of the Markdown files.
```yaml {filename="content/docs/guide/_index.md"}
---
title: Guide
weight: 2
---
```

It is recommended to keep the sidebar not too deep. If you have a lot of content, consider **splitting them into multiple sections**.

## Configure Content Directory
If we need to use a different directory for our content, we can do so by setting the [`contentDir`](https://gohugo.io/getting-started/configuration/#contentdir) parameter in our site configuration file.
To add images, the easiest way is to put the image files in the same directory as the Markdown file.
For example, add an image file `image.png` alongside the `my-page.md` file:
{{<filetree/container>}}
{{<filetree/foldername="content">}}
{{<filetree/foldername="docs">}}
{{<filetree/filename="my-page.md">}}
{{<filetree/filename="image.png">}}
{{< /filetree/folder >}}
{{< /filetree/folder >}}
{{< /filetree/container >}}
Then, we can use the following Markdown syntax to add the image to the content:
```markdown {filename="content/docs/my-page.md"}

```
We can also utilize the [page bundles][page-bundles] feature of Hugo to organize the image files together with the Markdown file. To achieve that, turn the `my-page.md` file into a directory `my-page` and put the content into a file named `index.md`, and put the image files inside the `my-page` directory:
