In mashape, internally, we are using subversion. But we wanted to open some code (the server and client libraries) on github (here our profile: github.com/Mashaper).

When you have to create a brand new github repository the process is pretty straightforward

• create a new repository on github
• enter your working copy
• git init
• create a new .gitignore with “.svn” as content
• git remote add origin $github-repo-url
• git add/commit and push

When the repository is already on github (maybe you are working from another pc) the process is a little bit tricky

• checkout from svn
• enter the working copy
• git clone –no-checkout $github-repo-url
• create a new .gitignore with “.svn” as content
• git reset and, if needed, checkout/add

in this way I can commit on both version control systems, to have the same location shared on subversion (needed for some internal scripts) and the open source version.

And, obviously, I can send and receive updates in each direction
