 ### Definitions
+We use content definitions to make it faster to track the effectiveness of different types of blog posts. There are three categories we use to differentiate blog content:
 
 1. **Content marketing:** Examples, education, reporting, storytelling, thought leadership, and use cases.
 1. **Corporate:** Company news, announcements, and community updates (ex: issue bash, contributor profiles).
 1. **Product:** Release posts, critical updates, and partnership announcements.
 
+Use the `postType` frontmatter option to set the content definition.

 ## Workflow
 
 We follow the [GitLab Workflow](/gitlab-flow/). At GitLab, everyone can contribute, and we encourage anyone to submit a blog post idea or write your own. Below are instructions on how to contribute to the GitLab blog.
