Expected Behaviour

• Add documentation for configuring flask secret key using environment variables on Local, Heroku and Docker.

It would be great if this could be hidden

the original secrete key is different

[pranav1698]

Also, I think this would require admin rights from the heroku server but you can test it for your local development

i have already changed it

Can I work on this ? If yes can you explain how to add something to documentation. Also # Initializing flask secret key using the environment variable "secret_key" app.secret_key = os.environ.get('secret_key', 'z528&^FJjhd_t2bxc#$2').encode() what is the second argument here? @alok760

@Patil2099 the second argument is the default value. To change the secret key, you need to set an environment variable secret_key. You already need to set your Travis Key as an env variable, similarly, you need to set the flask secret key.
