-## Autocomplete characters
-
-Many quick actions require a parameter, for example: username, milestone, and
-label. [Autocomplete characters](autocomplete_characters.md) can make it easier
-to enter a parameter, compared to selecting items from a list.
-
-## Quick actions parameters
-
-The easiest way to set parameters for quick actions is to use autocomplete. If
-you manually enter a parameter, it must be enclosed in double quotation marks
+Quick actions are text-based shortcuts for common actions that are usually done
+by selecting buttons or dropdowns in the GitLab user interface. You can enter
+these commands in the descriptions or comments of issues, epics, merge requests,
+and commits.
+
+Be sure to enter each quick action on a separate line to allow GitLab to
+properly detect and execute the commands.
+
+## Parameters
+
+Many quick actions require a parameter. For example, the `/assign` quick action
+requires a username. GitLab uses [autocomplete characters](autocomplete_characters.md)
+with quick actions to help users enter parameters, by providing a list of
+available values.
+
+If you manually enter a parameter, it must be enclosed in double quotation marks
 (`"`), unless it contains only these characters:
 
-1. ASCII letters.
-1. Numerals (0-9).
-1. Underscore (`_`), hyphen (`-`), question mark (`?`), dot (`.`), or ampersand (`&`).
+- ASCII letters
+- Numbers (0-9)
+- Underscore (`_`), hyphen (`-`), question mark (`?`), dot (`.`), or ampersand (`&`)
 
-Parameters are also case-sensitive. Autocomplete handles this, and the insertion
+Parameters are case-sensitive. Autocomplete handles this, and the insertion
 of quotation marks, automatically.
 
-## Quick actions for commit messages
+## Issues, merge requests, and epics
+
+The following quick actions are applicable to descriptions, discussions, and
+threads. Some quick actions might not be available to all subscription tiers.
