+###Telescope Plugin
+
+the telescope Plugin is used to track all git repository visited in one nvim session.
+
+__why a telescope Plugin__ ?
+Assuming you have one or more submodule(s) in your project and you want to commit changes in both the submodule(s)
+and the main repo. Though switching between submodules and main repo is not strait forward. My solution was at first,
+1. open a file inside the submodule
+2. open lazygit
+3. do commit
+4. then open a file in the main repo
+5. open lazygit
+6. do commit
+that was really and ennoying for me
+so I though about traking all the repo I visited an I can choose from the list which one I'd like to commit in.
