Hi there, welcome to Flarum !
The software is still in beta, so there's no particularly user-friendly way of installing it. However you have plenty of options:
- If you know how to use SSH and Composer, use the official documentation
- If you're on a shared hosting and/or only have experience with "classic" forum installers, have a look at Pockethold which is a workaround to skip the terminal and composer
- If you have no idea how this works, there are people offering to install it for you. Just use the search feature or ask on the Gitter channel
Hope this helps ?
