Writing guide

A guide on how to write documentation

This document is meant to be read alongside the style guide to provide concrete examples on formatting the document and syntax of different Hugo shortcodes.

Documentation overview

All Dolittle documentation is generated using Hugo 0.58.3, with the Dot theme.

Writing documentation


All files MUST have a metadata header at the top of the file following the Hugo Front Matter format. Some of this metadata gets put into the generated HTML file.

The keywords and title properties are used for searching while the description shows up in the search results.

title: About contributing to documentation
description: Learn about how to contribute to documentation
keywords: Contributing
author: dolittle
// for topmost _index.md files add the correct repository property
repository: https://github.com/dolittle/Documentation
weight: 2

The main landing pages also have an icon attribute in the Front-Matter. These icons are from the Themify icon pack.

Documentation filenames

All files MUST be lower cased, words MUST be separated with a dash. Example: csharp-coding-styles.md. Hugo also takes care of converting between dashes and underscores as well as lower- and uppercase.

Within same repository

When adding links to other pages inside the same repository DO NOT USE the file extension .md - otherwise the link will be broken. For instance, linking to the API documentation is done by adding a markdown link as follows:


Renders to:


Cross Repositories

Link pages from other repositories using Hugos relref/ref functions inside the markdown.

External resources

Linking to external resources is done in the standard Markdown way:

[Dolittle Home](https://github.com/dolittle/home)

Looks like this:

Dolittle Home

Diagrams / Figures

Hugo supports Mermaid shortcodes to write diagrams. Mermaid SHOULD be favored over using images when possible. Examples of Mermaid

Some diagrams/figures might not be possible to do using Mermaid, these can then be images. Beware however how you create these images and make sure they comply with the look and feel.


All images should be kept close to the markdown file using it. To make sure the folders aren’t getting cluttered and to have some structure, put images in a images folder.

Images should not have backgrounds that assume the background of the site, instead you SHOULD be using file formats with support for transparency such as png.

<repository root>
└── Documentation
    └── MyArea
        └── [markdown files]
            └── images
                [image files]

To display images use the standard markdown format:

Hugo supports different levels of alerts:


Use tips for practical, non-essential information.

{{% alert %}}
You can also create ReadModels with the CLI tool.
{{% /alert %}}

Renders to:


Use warnings for mandatory information that the user needs to know to protect the user from personal and/or data injury.

{{% alert color="warning" %}}
Do not remove `artifacts.json` if you do not know what you're doing.
{{% /alert %}}
