I followed this discussion here
https://discuss.flarum.org/d/1565-install-flarum-on-windows
And I was able to grab flarum files on my PC then I uploaded it to shared hosting server and it worked great! does it also need composer to be installed on the shared server to get flarum working after installation, sorry for the question i used to use xenforo and I'm not familiar with flarum yet, php programming is just a hobby for me that I've learned myself from online resources by errors and trials ?
I'm waiting for the stable release to use this software as a community ?
