setup

I'm following defunkt's gist setup guide.

[smotchkkiss ~]$ sudo gem install gist
[smotchkkiss ~]$ git config --global github.user "my github name"
[smotchkkiss ~]$ git config --global github.token "my github token"
[smotchkkiss ~]$ echo "puts 'hello, gist.'" > hello.rb
[smotchkkiss ~]$ gist hello.rb
