Uploading a code

sorry for asking this primary question but I want to run this code but can’t

how can I do this?

One way is that you can just copy the contents of that file into the index.html file in your project.

As an alternative, you can use the github import feature to import sitepoint-editors/Api-AI-Personal-Assistant-Demo in a project (note: this will remove any existing files present in the project and import from the github repo)
