Git-tracked Folder Within a Git-tracked Folder

Question

I developed a web project and tracked it with git. Later I had to use that project in another big project which is again tracked by git. Earlier I didn\'t have knowledge abo

Answer 1

If I change any thing in the small project within the big project, it is not getting tracked.

It is not being tracked because it was seen by the parent project as a gitlink for nested repo. That is, just a SHA1, not its actual content.

If your first repo was pushed somewhere remote, then you could add it as submodule of your main repo with git submodule add.

cd second/big/repo
git submodule add -- /url/first/repo

If not, you would need to recreate your first repo (outside the big repo), push it somewhere remote (GitHub, GitLab, Bitbucket, ...) and add it as submodule of your big repo.
