Re: Need help for my first Open Source Contribution.

Hi Siddhiraj,

Welcome to the open-source community! It's great to see you interested in 
contributing to Django. Here are some suggestions on how to get started:

   1. 
   
   Check out the Django Contributing Guide: 
   https://docs.djangoproject.com/en/stable/internals/contributing/. This 
   guide provides an overview of the different ways you can contribute to 
   Django.
   2. 
   
   If you're looking to contribute code, take a look at the "Advice for New 
   Contributors" section in the guide: 
   
https://docs.djangoproject.com/en/stable/internals/contributing/new-contributors/.
 
   This section provides some helpful tips and best practices for getting 
   started.
   3. 
   
   You can also work through the "Writing Your First Patch" tutorial: 
   https://docs.djangoproject.com/en/stable/intro/contributing/. This 
   tutorial walks you through the process of contributing a patch to Django.
   4. 
   
   If you get stuck or have any questions, don't hesitate to post back in 
   the django-developers group or the "Mentorship" section on the forum: 
   https://forum.djangoproject.com/c/internals/mentorship/10.
   
I hope this helps you get started with your first contribution to Django. 
Good luck!
