I'm using git-subtree(from Avery Pennarun). In my current git repo I have of course all my project files/folders and a subtree called "lib". If I now clone this git repo using git clone I get all of the project files and the subtree "lib" (everything as it should be). What I tried now: I changed something within the subtree "lib" in the cloned repo and tried to push the changes back to the remote repo of the subtree "lib" using git subtree push, but it didn't work. What is the problem? Do I have to add it as subtree first with git subtree add?

Thx in advance
