 ### REQUIREMENTS
 
 GitPython needs the `git` executable to be installed on the system and available
 in your `PATH` for most operations.
 If it is not in your `PATH`, you can help GitPython find it by setting
 the `GIT_PYTHON_GIT_EXECUTABLE=<path/to/git>` environment variable.
 
-* Git (1.7.x or newer)
-* Python >= 3.6
