 a verb, like Configuring, Enabling, etc.
 - **Introduction**: A couple sentences about the subject matter and what's to be found on this page.
 - **Overview** Describe what it is, what it does, and in what context it should be used.
 - **Use cases**: describes real use case scenarios for that feature/configuration.
-- **Requirements**: describes what software and/or configuration is required to be able to
-  use the feature and, if applicable, prerequisite knowledge for being able to follow/implement the tutorial.
-  For example, familiarity with GitLab CI/CD, an account on a third-party service, dependencies installed, etc.
-  Link each one to its most relevant resource; i.e., where the reader can go to begin to fullfil that requirement.

-### Feature overview and use cases
-
-Every major feature (regardless if present in GitLab Community or Enterprise editions)
-should present, at the beginning of the document, two main sections: **overview** and
-**use cases**. Every GitLab EE-only feature should also contain these sections.
-
-**Overview**: as the name suggests, the goal here is to provide an overview of the feature.
-Describe what it is, what it does, why it is important/cool/nice-to-have,
-what problem it solves, and what you can do with this feature that you couldn't
-do before.
-
-**Use cases**: provide at least two, ideally three, use cases for every major feature.
-You should answer this question: what can you do with this feature/change? Use cases
-are examples of how this feature or change can be used in real life.
-
-Examples:
+- **Requirements**: describes what software, configuration, account, or knowledge is required.
+- **Instructions**: One or more sets of detailed instructions to follow.
+- **Troubleshooting** guide (recommended but not required).
