+# 1. `git rm --cached <submodule_relative_path>`                # this removes the submodule entry from general git tracking
+# 2. `rm -rf .git/modules/<submodule_relative_path>`            # this removes the stale name entries in submodule tracker
+# 3. `rm -rf <submodule_relative_path>`                         # removes the submodule completely
+# 4. `git submodule --deinit <submodule_relative_path>`         # make sure that the submodule is de-inited too (ignore errors at this point)
+# 5. `git submodule add [-b <branch_name>] <repo_url> <submodule_relative_path>`    # This adds the submodule back into general git tracking and also adds to the submodule tracker
+# 6. Step 5 creates an entry in the .gitmodules when a submodule is added,
+#    So if you already had one entry, try to remove duplicates at this point
+# 7. `git submodule sync --recursive`                           # this now sets/updates the submodule repo url tracker into git config
+# 8. `git submodule update --init --recursive`                  # this now clones the updated repo set by .gitmodules
+#     But this will always fetch the latest commit sepecified by the custom(if set)/default branch
+# 9. If you do want to have a specific commit in that submodule branch and not latest, you need to perform normal detached head checkout and check-in as follows:
+#    `pushd <submodule_relative_path>`                          # switch to the submodule repo
+#    `git checkout <commit-id>`                                 # this creates a detached head state
+#    `popd`                                                     # get back to parent repo
+#    `git add <submodule_relative_path>`                        # check-in the changes in parent for this submodule link (tracker)
+#    `git commit -m <commit-message>`                           # commit it to parent repo        
+#    `git push`                                                 # push to parent repo to preserve this entire change in the submodule repo/link file
+#
+#  NOTES:
+#  1. updating just this .gitmodules file is NOT ENOUGH when changing repo url and performing a simple `git submodule update --init --recursive`, need to do all the above listed steps for proper tracking
+#  2. updating the branch in this .gitmodules for same repo is okay as long as `git submodule update --init --recursive` is also performed followed by it
+#  3. Ensure there is no stale entries or duplicate entries in this .gitmodules file coz, `git submodule add ...` creates an entry here.
