Documentation topic types (CTRT)
Each topic on a page should be one of the following topic types:
Even if a page is short, the page usually starts with a concept and then includes a task or reference topic.
The tech writing team sometimes uses the acronym
CTRT to refer to the topic types.
The acronym refers to the first letter of each topic type.
Other page and topic types
In addition to the four primary topic types, you can use the following:
- Page type: Tutorials
- Topic type: Related topics
- Page or topic type: Glossaries
Pages and topics to avoid
You should avoid:
- Pages that are exclusively links to other pages. The only exception are top-level pages that aid with navigation.
- Topics that have one or two sentences only. In these cases:
- Incorporate the information in another topic.
- If the sentence links to another page, use a Related topics link instead.
- Get started topics. To document a procedure for a single feature, use a task. For a set of steps, use a tutorial.
Topic title guidelines
In general, for topic titles:
- Be clear and direct. Make every word count.
- Use articles and prepositions.
- Follow capitalization guidelines.
- Do not repeat text from earlier topic titles. For example, if the page is about merge requests,
Troubleshooting merge requests, use only

If inline links are not sufficient, you can create a topic called Related topics and include an unordered list of related topics. This topic should be above the Troubleshooting section.
Links in this section should be brief and scannable. They are usually not full sentences, and so should not end in a period.
