Topic Structure

When creating a topic, you will need to follow a certain structure. A topic generally comprises of, in order:

  • Metadata (Specific for .md files in Gardener) - Additional information about the topic.

  • Title - A short, descriptive name for the topic.

  • Content - The main part of the topic. It contains all the information relevant to the user.

  • Related Links (Optional) - A part after the main content that contains links that are not a part of the topic, but are still connected to it.

You can use the provided content description files as a template for your own topics.


Metadata is information housed in a specific section of the .md files used for the Gardener documentation. It can contain:

  • Title - A short, descriptive name for the topic.
  • Description - A succint summary of the topic’s content. Must not include the title or repeat content from the topic.
  • Other elements such as weight, creation date, author and tags.

Sample codeblock:


While this section will be automatically generated if your topic has a title header, adding more detailed information helps other users, developers and technical writers better sort, classify and understand the topic.

By using a metadata section you can also skip adding a title header or overwrite it in the navigation section.

General Tips

  • Try to create a succint title and an informative description for your topics.
  • If a topic feels too long, it might be better to split it into a few different ones.
  • Avoid having have more than ten steps in one a task topic.
  • When writing a tutorial, link the tasks used in it instead of copying their content.

Language and Grammar


  • Gardener documentation uses US English.
  • Keep it simple and use words that non-native English speakers are also familiar with.
  • Use the Merriam-Webster Dictionary when checking the spelling of words.

Writing Style

  • Write in a conversational manner and use simple present tense.
  • Be friendly and refer to the person reading your content as “you”, instead of standard terms such as “user”.
  • Use an active voice - make it clear who is performing the action.

Creating Titles and Headers

  • Use title case when creating titles or headers.
  • Avoid adding additional formatting to the title or header.
  • Concept and reference topic titles should be simple and succint.
  • Task and tutorial topic titles begin with a verb.
