About Transmission
Transmission is a fast, easy, and free BitTorrent client. It comes in several flavors:
- A native macOS GUI application
- GTK+ and Qt GUI applications for Linux, BSD, etc.
- A Qt-based Windows-compatible GUI application
- A headless daemon for servers and routers
- A web UI for remote controlling any of the above

Documentation
[Transmission's documentation](docs/README.md) is currently out-of-date, but the team has recently begun a new project to update it and is looking for volunteers. If you're interested, please feel free to submit pull requests!
Command line interface notes
Transmission is fully supported in transmission-remote, the preferred cli client.
Three standalone tools to examine, create, and edit .torrent files exist: transmission-show, transmission-create, and transmission-edit, respectively.
Prior to development of transmission-remote, the standalone client transmission-cli was created. Limited to a single torrent at a time, transmission-cli is deprecated and exists primarily to support older hardware dependent upon it. In almost all instances, transmission-remote should be used instead.
Different distributions may choose to package any or all of these tools in one or more separate packages.
Code Style
You would want to setup your editor to make use of the .clang-format file located in the root of this repository and the eslint/prettier rules in web/package.json.
If for some reason you are unwilling or unable to do so, there is a shell script which you can use: ./code_style.sh
