How to reproduce: - The [documentation](https://docs.sunfounder.com/projects/picar-x-v20/en/latest/python/python_start/install_all_modules.html#) asks to install pixar-x with branch 2.1.x (git clone -b 2.1.x https://github.com/sunfounder/picar-x.git --depth 1) - In the next step, it asks you to run the i2samp.sh script from pixar-x - However, the 2.1.x branch does not contain a i2samp.sh script. See: https://github.com/sunfounder/picar-x/tree/2.1.x - But the v2.0 does So, which branch to use, the v2.0 or 2.1.x?
