Does Git ignore directories that are themselves Git repos, by default? -

basically, question in subject line, git ignore directories git repos, default?

i asking because created git repo in folder contained few other repos in subfolders, along other files wanted track.

i surprised find new git repo appeared automatically ignore files of git repos in sub-directories.

yes, feature of git. if initialize git repository in subfolder, try add folder parent folder's git repository, folder's git history won't include subfolder's files.

you can modify files , try add them, you'll message modified: some_dir (modified content, untracked content). directory name tracked.

submodules create address common scenario. allow keep git repository subdirectory of git repository. if need track parent , subfolders, submodules let that.

this documentation provides step-by-step guide.
