Looks good. @stanzheng would you mind taking a look at this on mac?

Not too familiar with what the issue is, I pulled down the changes and ran some commands.
Everything looks as expected behaviors, no conflicts. The README in /usr/local/ is still installed but no conflicts are created.

@stanzheng the README shouldn't be there on a clean install. It apparently screws up homebrew (#158)

I mean I ran these series of commands. It still installs the README on each edit. Why not add something that just nerfs the readme after install?
