+Complete step [4.1](https://docs.nvidia.com/ngc/ngc-overview/index.html#account-signup) and [4.3](https://docs.nvidia.com/ngc/ngc-overview/index.html#generating-api-key). Save the API key.  
 
-- [ ] [Create](https://docs.gitlab.com/ee/user/project/repository/web_editor.html#create-a-file) or [upload](https://docs.gitlab.com/ee/user/project/repository/web_editor.html#upload-a-file) files
-- [ ] [Add files using the command line](https://docs.gitlab.com/ee/gitlab-basics/add-file.html#add-a-file-using-the-command-line) or push an existing Git repository with the following command:
+Add the API key to the config file at ```~/.config/enroot/.credentials  ```  
+```
+machine nvcr.io login $oauthtoken password your_api_key
+machine authn.nvidia.com login $oauthtoken password your_api_key
+```
+
+Set the config path by adding the line to ```~/.bashrc```
+```
+export ENROOT_CONFIG_PATH=/home/xuagu37/.config/enroot
+```
 
+To make the path valid
 ```
-cd existing_repo
-git remote add origin https://gitlab.liu.se/xuagu37/run-pytorch-and-tensorflow-containers-with-nvidia-enroot.git
-git branch -M main
-git push -uf origin main
+source ~/.bashrc
 ```
