      Welcome to **The Virus Lounge**. We're a group of people who got
      together in 2020, when we felt that there was not enough
      spontaneous socialising on the internet.

      Because of our shared interests in topics like **build systems**
      and **monorepos** we started working on code together, in our
      monorepo called the *depot*.

      Feel free to explore the tech we have built so far, all our
      systems are linked in the footer.

      We mostly hang out on IRC. You can find us in [`#tvl`][tvl-irc]
      on [hackint][], which is also reachable [via XMPP][hackint-xmpp]
      at [`#tvl@irc.hackint.org`][tvl-xmpp] (sic!).

      Hackint also provide a [web chat][tvl-webchat].

      ## Where did all these people come from?

      It's pretty straightforward. Feel free to click on people, too.
