# Description

Due to limitations from PyPI, all dependency packages have to be
published pip packages.
Unfortunately, RSL RL currently does not have a pip package, so we could
not include it into the Isaac Lab package.
This PR adds the instructions to install RSL RL separately from pip when
using pip installed Isaac Lab.
