There are a couple of steps, and this is a little less detailed, we can flesh it out as more comes up.

You'll probably need to do a production build with a full .env file fleshed out locally, composer require, npm install, the works.  Run your migrations against your production database from your command line,

Copy the following folders and their contents to your root:
1. vendor
2. Storage
3. routes
4. resources
5. node_modules
6. database
7. config
8. bootstrap
9. app

Copy the following files to your root:
vite.config.ts
ts.config.json
synagogue.png
phpunit.xml
package.json
package-lock.json
eslint.config.js
composer.lock
composer.json
.env with your proper configurations, i.e. MySQL or PostGres configuration.

If you have wwwroot vs. public, you'll want to copy public and its contents there, too.  Copy the contents of public to wwwroot if you have it.  

You may have to alter index.php to get the right location for vendor autoload.  Make sure you have access to your logging, both in your shared hosting or in your /storage/logs folder so you can figure out any additional configuration issues.
