Installation

OS	File	How
Windows	Wttp-<version>-setup.exe	Download and run. The installer asks for confirmation (UAC) once.
macOS	Wttp-<version>-<arch>.dmg	Download, open the .dmg and drag Wttp to Applications.
Linux	Wttp-<version>-amd64.deb or .AppImage	.deb: sudo dpkg -i Wttp-*.deb. .AppImage: chmod +x, then run it.

Download from the GitHub Releases page. Every release ships the artifacts for all three platforms plus a SHA256SUMS-<OS>.txt so you can verify the download before installing.

Updates

The app checks for a new version on startup and every few hours, downloads it in the background, and only swaps the binary on the next restart — or when you click Update now. You can turn this off in Preferences → Updates.

Installed from the .deb?

Then updates come from your package manager (apt/dpkg), not from inside the app.

Language and theme

In Preferences → General you pick the language (English, Português, or follow the system) and the theme (light, dark or system). Both apply immediately, no restart.

Documentation inside the app

Preferences → About has two buttons: one opens this documentation in your browser, the other opens a copy bundled with the app — it works offline.
