How to get the full backup of my project that I can use to publish it using Bluehost.

Dear Community,

I am running into an issue. I completed my project using this great tool, but I have not been able to publish it and get it online.

I have my domain and hosting with Bluehost. I managed to get a full backup from GitHub after creating a repository. The tech support is telling me that the files are missing an index file, which I believe does not exist, as the project was built using JS. Any thoughts and comments on how to get my site online?

I am not an expert, which is adding a bit more complexity to this process that may look simple for most experts.

Thank you,

Carlos Galvis
