+### deleting a project
+
+If you ever need to delete an entire project, you can do so from the Project Selection screen.
+
+To delete a project:
+
+1. from the Project Selection screen, position your cursor on the project you wish to delete
+2. press `A + B`
+3. a confirmation dialog will appear showing the project name and asking you to confirm the deletion
+4. select `yes` to delete the project permanently, or `no` to cancel
+
+**be careful!** deletion is permanent and cannot be undone. make sure you have backed up your work if you wish to keep it. the entire project directory will be removed, including all songs, chains, phrases, and any associated data.
+
+it's always a good idea to keep backups of important projects before deleting anything!

+## Safely Deleting Projects
+
+Since version 1.6.0, you can delete projects directly from the Project Selection screen by pressing `A+B`. This is a convenient way to clean up old or unwanted projects.
+
+**Best Practices:**
+- **Always back up important projects** before deleting. Use your operating system's file manager to copy project directories to an external drive or backup location.
+- The deletion will remove the entire project directory permanently - this cannot be undone!
+- A confirmation dialog will appear showing the project name before deletion proceeds, giving you a chance to cancel if you selected the wrong project.
+- After deletion, the project list will refresh automatically and the cursor will stay near its previous position for your convenience.
+
+**Pro Tip:** Use Save As to store a duplicate of the project if you're uncertain if you should delete something
