+The work package info line is a consistent way to display the most commonly-used  set of basic work package attributes.
+
+## Overview
+
+<%= embed OpenProject::WorkPackages::InfoLineComponentPreview, :playground %>
+
+## Anatomy
+
+The info line consists of three attributes that are displayed together:
+
+- Type
+- ID
+- Status
+
+Only the ID the only interactive element; it is clickable and points the work package. All other interaction has to come from the element using this work component.
+
+## Best practices
+
+It's best to not separate these three elements in different lines. The element can, however, be wrapped in multi-line if needed.
+
+## Used in
+
+- Hovercard
+- Work package relations tab
+- Work package header
+- ...
+
+### Code structure
+
+You can typically call the InfoLineComponent in views where work package details (Type, ID, and Status) need to be displayed in one line. You must pass a work package object containing valid data to it.
+
+```html
+    render(WorkPackages::InfoLineComponent.new(work_package: @work_package))
+```
