Hi everyone,
I just have a problem installing flarum, as I don't know where to access installer of flarum, after excuted "composer create-project flarum/flarum . --stability=beta" on PuTTy.
I use siteground as my host, and I already get through all to access via SSH.
here is my detailed process:
First part.
I executed composer create-project flarum/flarum . --stability=beta, and get this result, and I know probably my directory is not empty, so I try to install it in a new folder kkk.

Second part.
I executed composer create-project flarum/flarum kkk --stability=beta`, because from this post https://discuss.flarum.org/d/1618-error-invalidargumentexception-project-directory-is-not-empty/12, @Kulga said it can install in a new folder, I just name my new folder kkk.
and I got this results.


and I found that, when I visit my domain on Chrome, no matter I visit https://mydomain.com/, or visit https://mydomain.com/kkk, I only see this.

and in my siteground file manager, when I tried to access to files, it just showed

Here are my questions:
Did I successfully install composer on my host?
Where can I access to install flarum page like this?

If I was wrong, any suggestion for me to solve this problem?
Thank you in advance.
Kurtis
