Next, by restarting Steam and installing its beta version, you can make translation settings. You can choose among the following options:
* Only friends whom I invite will be able to watch my streams;
* Friends can request permission to view the streams of my games (by default);
* Friends can watch streams of my games without asking for permissions;
* Any user can watch streams of my games (public broadcast, can be found in the game hub).
The broadcast begins as soon as someone starts watching it.
To join the viewing of any broadcast, find it in the hub, or in the profile of a friend.

At the moment, the viewing of broadcasts is available through the beta version of the Steam client, Google Chrome browsers and Apple Safari. Also, there is no recording of broadcasts, as well as monetization. It may appear in the future.

You can stream not only games, but everything you want, such as your desktop, the process of developing a game or a program.
