Style Guides

Tech writers follow style guides for technical and UX writing, most of which adhere to similar industry standards. These outline and define best practices for clear, consistent, and useful content, such as guidelines for capitalization, headings, and serial commas. 

Creating and maintaining your own style guide can be time-consuming and conflict-inducing. Adopting a single, existing style guide helps avoid arguments and editorial decisions that suit the preferences of the person with the strongest opinions.


Below is a list of well-established style guides and other sources of editorial guidance in the tech community. This isn't an exhaustive list. Rather, the references provided offer common best practice guidance for technical writing.

Guidelines aren't rules. They should be followed insofar as they help you write readable content for your target audience in the context of your brand's voice and tone. Style guides are often typically living documents, with growing word lists and changes to specific guidelines based on new knowledge and understanding of how people digest content. ​
