Create, push, and pull a Github repository for reliability-aging project on a Snow Leopard laptop.

I created a repository on GitHub website, then download the ZIP template directory, and find out the https site. 
 
$ pwd/Users/hongqin/github/reliability_aging
$ git init
$ git add *R
$ git commit -m "first reliability commit"

$ git remote add origin https://github.com/hongqin/reliability_aging.git

$ git push --force origin master 

I then added a README on GitHub website. 

$ git pull origin master
From https://github.com/hongqin/reliability_aging
 * branch            master     -> FETCH_HEAD
Updating 3a05312..8b48895
error: The following untracked working tree files would be overwritten by merge:
 README.md
Please move or remove them before you can merge.
Aborting
ace:reliability_aging-master hongqin$ ls README.md 
README.md

This is confusing. "README.md" is pulled, but there is an error. 

$ git add perfect.repair.20130417.R

$ git commit -m "after pull error"
