 ## Usage
 
 To trigger the bot, you need to write a comment in a Pull Request where the action is installed. The available actions are:
-- `/bot merge`: Enables auto-merge for Pull Request
-- `/bot cancel`: Cancels auto-merge for Pull Request
-- `/bot help`: Shows this menu
+- `/merge`: Enables auto-merge for Pull Request
+- `/merge cancel`: Cancels auto-merge for Pull Request
+- `/merge help`: Shows this menu
 
 The bot can only be triggered by the author of the PR or by users who *publicly* belongs to the organization of the repository.
 
 By publicly, I refer to the members of an organization which can be seen by external parties. If you are not sure if you are part of an organization, simply open https://github.com/orgs/**your_organization**/people in a private window. If you don’t see your name there, you are not a public member.
