Specify the location: Provide a link to the relevant article or section where you want the change made.
Describe the problem or change: Write a detailed description of what is wrong or what needs to change. Screen caps are helpful.
Suggest a fix: Propose a solution or describe how the issue should be addressed. If you are proposing a new topic (such as a new feature), include links to internal docs with information about that topic/feature (user stories, feature requirements, etc).

If you would like to make the changes yourself, assign the ticket to yourself and follow the instructions below to contribute directly in Confluence.
