Notepad Next Notepad++

currently on fedora so I used this to setup flathub, otherwise use this link:

https://flatpak.org/setup/ to find your distro.

Fedora:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Then to install NotepadNext, try:

flatpak install flathub com.github.dail8859.NotepadNext
