Clear installation guide for Linux users

[MuhammadyusufEngineer]

I use Ubuntu and Installed Zen browser, It was zip folder, I had to do a lot of work to completely install and make it work, it's ok but it was not instructed on website, I managed to make it work using AI but still had issues to run it properly then I installed from Flatpak but still have this problems

• If I click the link it opens Firefox
• Every time it asks to set Zen as default browser, even I click to set it

So It would be better clear, complete installation guide to install Zen browser on Linux systems and that would help everyone
