Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

I am including some commands for GIT related tasks that can come handy

1. git pull upstream develop ==== pull from base/fork branch original from where we have forked to.
    git pull origin develop ===== pull from same org (or forked) repo.
    cherry-pick == pick specific checking in a branch. There is a dry run mode and a commit mode.

A very important command that i learnt was a git cherry-pick , that is usefulll in cases wher you want to move only a perticular commit from other branch
to your branch. In regular cases if you merge 2 branches all teh changes (from head) are merged to target. 

e.g. git cherry-pick -n <commit>

-n option is important , as the command keeps the changes in your working files, if not given checkes in the change.

At times you may be gated to not checking some files due to dependency on reviewer or functiolnality not completely. Simply say , tha you have to share your changes
and at the same time you cannot chcking. ut you still want to share the change with the team . e.g. change in the bottomose layer like entties and and persistanc layes

One way is to create a new branch and ask other to switch , but this leads to nested merges later on. I found a simply way is to use a patch

I used it via Eclispse PATCH Team>Crat PAtch ... . This will ask you to create multiple patch files depending on your project and then thei patch file can be sahted wiuth the team to appy 
locally. Voilla !! 

So when thigs are checked in the patch can be removed. This is helpfull when you are mergin and you got issue, You can simply refert the patched files and lonce merge issue areresolved path again.
