I've been using Flarum for a forum website. But I found no easy way to install any extensions. I found that I have to use SSH but my hosting doesn't share SSH. I need to do it manually. How can I do that?
You can find some tips for that situation here https://docs.flarum.org/composer#i-dont-have-ssh-access
A host with SSH is highly recommended to take full advantage of Flarum.
