+### I set the wrong remote repository.
+
+There are a few possible problems here:
+
+
+If you cloned the wrong respistory simply delete the directory created after running git clone and clone the correct repository
+
+
+If you set the wrong repository as the origin of an existing local repository, change the url of your origin by running 
+
+```sh
+$ git remote set-url origin [url of the actual repo]
+```
