[twitch.tv](https://www.twitch.tv) is an online streaming platform commonly used for people to watch people play computer games. It is also suitable for live streaming lectures however.
#### Going live on Twitch
In order to go live on twitch.tv you will first need to create an account there. With the account created go to [your dashboard](https://dashboard.twitch.tv/). In your dashboard in the menu on the left (open it by clicking the menu bottom in the top left) go to "Preferences" -> "Channel". This is where you can find your `Primary Stream Key` which you will need to input into a program like OBS (see below) to actually get your content to show up on Twitch.
##### Setting up OBS
##### Finalising the set-up.
On your main channel page (twitch.tv/<your_username>) you can edit the title of your stream and other settings by clicking the pencil icon in the bottom right.
In this menu we recommend changing the title of your stream to match the content (e.g. "Automata, Computability & Complexity, Lecture week 5"). We recommend adding the `English` tag, but leaving the category empty (that way it is harder for random strangers to find an join your audience).
#### Moderating Twitch Chat (thanks to our TA Yoshi van den Akker for text contributions)
Twitch comes with a chat feature in which viewers can comment and ask questions to the live streamer. For [interactive lectures](Interactive Lectures) this can be a good way to receive questions from the students.
