Add new repo:
git submodule add https://git2.tavasi.ir/front/chat_ui.git systems/chat_ui -f

Cloning a Repository with Submodules
If you clone a repository that contains submodules, you'll need to initialize and update the submodules:
git clone <repository-url>
cd <repository-directory>
git submodule init
git submodule update

Or, you can do it in one step:
git clone --recurse-submodules <repository-url>

Updating Submodules
To update a submodule to the latest commit on its branch:
git submodule update --remote

## How to Remove an Existing Submodule

If the path was previously added as a submodule, you need to remove it completely before re-adding it. Follow these steps:

1.  Remove the submodule entry from .gitmodules.
2.  Remove the submodule from the working tree and index: git rm --cached <path-to-submodule>.
3.  Delete the submodule directory: rm -rf <path-to-submodule>.
4.  Stage the .gitmodules changes: git add .gitmodules.
5.  Commit the changes: git commit -m "Removed submodule <submodule-name>".

errors:

# repo already exists and is not a valid git repo

Check if the path is already tracked
git ls-files --stage systems/chat_ui (100644 <hash> 0 <path>)

If it is, remove it from the index
git rm --cached systems/chat_ui

If system/chat_ui exits, remote it(chat_ui)
rm -r systems/chat_ui

Add the submodule
git submodule add https://github.com/example/repo.git systems/chat_ui

Commit the changes
git commit -m "Added submodule at systems/chat_ui"

Verify the submodule
git submodule status

(Optional) Initialize and Update the Submodule
If the submodule was added successfully but not initialized, run:
git submodule update --init --recursive
