 #Lightweight
 Github's "Clone in Desktop" button only works if the official Github.app is installed on OS X. The [Github.app](https://mac.github.com) spawns a [helper "GitHub Conduit.app"](https://help.github.com/articles/github-conduit) which will always be running on the system. This helper has a webserver constantly listening for requests on the users local machine port 25035. If the Github website can reach this server it changes the "Clone in Desktop" button links to open in the users local Git App instead of redirecting to https://mac.github.com.
 
-The Safari extensions eliminates the need to have a local webserver process running by injecting [7 lines of code](https://github.com/gdelmas/GithubTower/blob/master/src-safari/GithubTower.safariextension/main.js) only into Github's website.
