By yihui:

1. you can use `git rm your.file` to remove a file (if you work on Windows, I recommend TortoiseGIT to manage your git repositories; in this case you can simply right click and delete the file)
2. just add an extension to readme as readme.md (or readme.markdown); in command line, you can use `git mv README README.md`
