I use local subversion/tortoisesvn for code repository.
I want to also use github on the same code.
Will simply installing the github repository and client etc.. work without removing the files from the subversion repository?
It seems to me like there should be issues. for example which client decides which icons will be shown near the files in the windows explorer etc….
You don’t want the working trees to be on top of each other.
Look into using git-svn, which lets you treat your svn repository as a remote git repository.
Create a git repository, populate it with a pull from the svn repository via git-svn, and push that to github.
