Setting up SVN to GitLab mirror - what path to set GIT_REPO_PATH to?

Trying to create a SVN to GitLab mirror using the instructions at the following URL:

I’m lost on what path to set the GIT_REPO_PATH environment variable to? Since I’m fairly new to Git, I’m guessing that I have to install git onto the svn server and create a local repository to the GitLab repository, then use the path of the local repository. Is this correct?

Thanks, Gary.
