 There are different ways of turning a vanilla Linux system into a real-time capable operating system. As outlined in [`doc/RealTimeLinux.md`](./doc/RealTimeLinux.md) **[`PREEMPT_RT`](https://wiki.linuxfoundation.org/realtime/start)** is likely the most future-proof possibility as it is about to be included into the mainline of Linux. As of Ubuntu 22.04 it is also available to Ubuntu users out of the box with [Ubuntu Pro](https://ubuntu.com/pro).

 ### 1.2 Setting up real-time privileges
 
-After having patched your system and restarted it, booting into the freshly installed kernel, you should already be good to go to launch a real-time capable Docker. In case you do not intend to use [`root` as the user inside the Docker](https://medium.com/jobteaser-dev-team/docker-user-best-practices-a8d2ca5205f4) you furthermore will have to have give yourself a name of a user that belongs to a group with **real-time privileges on your host computer**. How this can be done can be found in [`doc/PreemptRt.md`](./doc/PreemptRt.md).
