Flarum: Has anyone used this forum engine?

Question

CMS

I really liked the engine. Beautiful. Adaptive. On ajax. But I didn't quite understand how to install it.
The documentation says, just clone and then php flarum / flarum install
if you do this, it swears that there are no files in flarum / core
at the root there is a build.sh script, it creates an archive in / tmp. looks like a complete assembly. I've already been able to get php flarum/flarum install to work from the command line, but the front still doesn't want to work. when entering, it writes Cannot GET flarum.loc i.e. the page I'm asking for...

Answer 1

If you go to the flarium directory in the repository, you can see that the core is included as a git submodule.
In this case, you need to install the submodules too .
Composer is there too. You can use it in the flarium directory instead of installing Git submodules.
UPD: Updated the answer, because. noticed the presence of Composer there.
