 [Git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules) is now supported as part of CI/CD on your project.
 
-If you're already established your project repos outside the AL Go template, you may use submodule instead of placing and commiting your code directly to the repo generated by this template.
-
-To use the Git submodule just simply remove entirely your project folder and replace it by adding your repo as submodule by running git command:
-
-```
-git submodule add <url to your project git>
-```
-
-Then commit the changes.
-
-To update your submodule, simply run:
-
-```
-git submodule update --remote --merge
-```
-
-The CI/CD process will now pull any repos (or _initialize the submodule_) inside of your AL Go repo according to the submodule file that you have committed.
