Thanks for your reply. Is there really no way of using daphne without 
altering nginx/supervisord config like we use gunicorn?
If not, I have some questions based on my efforts so far, please. I will be 
grateful for your attention to these. Apologies if they're silly questions 
since I'm a beginner:
1. If I reconfigure nginx and supervisord, how should I make sure the conf 
files get picked up by GAE? Should I add something to the app.yaml file to 
point to the nginx-app.conf file in the root folder? Should I also change 
my runtime declaration to custom, or leave it as python? I find that 
whenever I add an nginx-app.conf file in the root folder the build times 
out and I get an Error[4] from gcloud app deploy. Otherwise the build 
completes fully.
2. If I am starting a Unix socket for Daphne in the supervisord config 
file, what happens to the entrypoint delaration in the ap.yaml file? Do I 
delete that?
3. How do I know what path I should use in the command: "daphne -u /run/
daphne/daphne%(process_num)d.sock". Also, what is process_num?
4. The new conf files (for nginx and supervisord in the documentation 
shared by you) refer to localhost:8000 - should I change this? What is the 
TCP socket used by nginx backend?
5. How can I do things like updating supervisor, "sudo service nginx 
reload" etc on the GAE PaaS platform since I'm not operating the instance 
directly? Or is this not necessary since I'm creating a whole new build 
each time?

Sorry for the barrage and thanks in advance,
Rahul.
