 ## :computer: Pre-requisites for participants  
-* Participants require to bring their own computers either with CPU or GPU. Computers with GPU will be idea to prototype models. However, we will also prepare pre-training models and simple AI workflows that does not require GPUs. 
-* Have a Github username. Otherwise, [sign up](https://docs.github.com/en/get-started/signing-up-for-github/signing-up-for-a-new-github-account) to GitHub to create an account.
