@Vishnu.Atma This is an issue with your ssh keys not being added to your GitHub account. You can either generate and/or add your ssh keys to GitHub and clone the repo using SSH, or you can download the repo directly from GitHub by clicking the download button.
Hi jsuis , I have already downloaded the repository .but could suggest me the next steps after that … found it a bit confusing
Once you have the workshop materials downloaded - flow through each lab reviewing the instructions for each -
To get the associated nerdpack running, just CD into the folder & serve as normal.
cd $home/nr1-workshop/lab0 npm install nr1 nerdpack:serve (NOTE `npm start` will also work here)
Cycle through each lab exercise and let us know if you have any troubles along the way.
