Laravel install on existing website will it overwrite anything?

I am making a small login page for employees whereafter they will hit a dashboard to view pdf files like manuals and things maybe sign certain things that admins will assign to them.

So I made a little html css php login gets a plaintext user password from myphpadmin (testing purposes) then I started looking into registration and security. Sure I can probably make all this in php and be somewhat secure I’d like to have a decent featureset: register ,auth csrf login cookies remember me etc.

So laravel installs from hestias control panel quick app install.

My site is quite simple 4 pages html css static of course.
The employee page will be seperate from the main site. If I install it from the quick install will it overwrite anything in my domains public folder ? Index.html etc?

Can I install to a specific directory instead of public like : /public/portal?

Quick insrtall doens’t support it but you can always do it manually …
