Great. I reviewed the MR and added 1 request.

Added few more suggestion on the MR.

Hi
I made the suggested changes in the Readme.md file

1. Replaced the ##Installation section with the text example from the template.
2. Left the pathauto note as it is.
3. Removed Maintainer section as suggested.
4. Added newline at the end of document.

Please review.

Hi akulsaxena

For the #Subpathauto section, for better readability. I prefer this The Subpathauto module extends the functionality of the Pathauto module by enabling automatic URL alias creation for sub-paths of existing aliases. This feature helps maintain consistency and usability for nested paths within your Drupal site.
And the #Subpathauto section missing a project page and issue queue links.
Make sure alsotext manually word-wrapped within around 80 cols, as Per README.md template.

Thanks.

Sorry, my commit message has wrong spelling for "Updated".
Anyways, Made the suggested changes
