 rts
 ===
 rts - as in `*r*eal-*t*ime *s*settings` is a script used by a |systemd| |systemd.service|, allowing to set pre-defined real-time related scheduling settings.
+Its service files are dependant upon the real-time kernel, which means, they will only start if */sys/kernel/realtime* is present and not empty.
 This software and all of its components are licensed under the GPLv3.

-"REALTIME" kernel parameter
----------------------------
-| *rts.service* and *rts@.service* are dependant on the |kernel_parameter| *"systemd.setenv=REALTIME=true"*. The option itself sets nothing but an Environment for systemd.
-| This enables the services to by using *ConditionKernelCommandLine* in their *[Unit]* sections, if running a |real-time_kernel|.
-| Simply add this to your kernel parameters (for |linux-rt|), using |grub|, |syslinux|, or |systemd-boot|:
-
-  .. code:: bash
-
-    systemd.setenv=REALTIME=true
-
 Usage
 -----
 | When starting the systemd service *rts.service*, the general settings file */etc/rts/rts* will be sourced.
