flameshot is a screenshot tool that aims to be powerful yet simple-to-use. Its notable features include customizable appearance, in-app screenshot editing, D-Bus interface, tray icon support, experimental GNOME/KDE Wayland support, integration with Imgur and support for both GUI and CLI interface.

Besides the usage information about flameshot in this manpage, you can find similar information using flameshot --help. Same --help can be used for each subcommand as well to get the valid arguments for them. The detailed usage of flameshot is documented in the README.md file on the project's Git repository page: https://github.com/flameshot-org/flameshot
