Hello,
I read the Debian developers guide, but didn't find exactly how and
what to do.
I want to know what is the exact thing developers do .
My current understanding (you can answer the question and querries and
comment in pints to correct my understanding or adding details):-

1.Clone the salsa package repo
2.use the "gbp import-orig --uscan" to get the actual latest upstream
repo from github or from where the original git remote is hosted
3.use "dch -i" to edit changelog 
	[1]Querry: The repo which we clone is a debinzed repo right?
So when we dch -i we are changing changlog of debianized repo , is this
correct?
	[2]Querry: Should we make changes in this repo?
	[3]Querry: Have I misunderstood something ? Am i supposed to
unzip the tarball which "gbp import-orig --uscan" and make changes in
that directory?
4. use "gbp pq import" this adds a patch queue brach ig?
5. make chages in code (patches)
6. git add.
7. git commit -m "patch message Gbp-Pq: Name fix-the-foo.patch"
8. use "gbp pq export" this 
9.use "gbp buildpackage --git-pbuilder" builds the package with
pathches
10.use "autopkgtest" test the built package

[4]Querry: how to upload the finished work and where to upload? a nice
member suggested me to you my namespace in salsa debian.
