+# How to add submodules to a gitrepo
+
+If you want to use another git repo within your repo but still get updates from
+or contribute to the upstream repo without breaking things, then you need to add
+the repo as a submodule. this tells git that this folder is another repo and it
+will add a link to it and not cause problems.
+
+Step1:
+go to your repo. Use the following command instead of pull:
+`
+ git submodule add <link to repo> <path (if no path is provided the current folder is used.)>
+`
