Hello, I'm trying to do this under Windows 7 and Git 2.13.3.windows.1 and I get following error:
...
­> git remote add feature/singleLevelTest /c/stash/test_manager/.git

git pull feature/singleLevelTest master
fatal: refusing to merge unrelated histories

Any idea why ?

@simonferronforget, You can use --allow-unrelated-histories to force the merge to happen. Source: StackOverflow
