Is there a naming convention for git repositories?

Question

For example, I have a RESTful service called Purchase Service. Should I name my repository:

1. purchaserestservice
2. purchase-rest-service

Answer 1

lowercase-with-hyphens is the style I most often see on GitHub.*

lowercase_with_underscores is probably the second most popular style I see.

The former is my preference because it saves keystrokes.
