 ```
 
 The helper checks for an existing open PR with the same base/head and returns it instead of creating a duplicate.
+If the PR body needs to be changed after creation, update it from a body file:
+
+```powershell
+npm run pr:update -- --number <pr-number> --body-file <body-file>
+```
 
 For stacked work, pass the parent PR branch as `<base>`. For standalone work, pass `main`.
