nios-bsp fails with commands from readme file

I installed 23.1 in windows and linux.

I found a minimal max 10 demo for nios V/c

The instructions to make the design don't work.

- Invoke the quartus_py shell in the terminal
- Run the following command in the terminal from top level project directory:
> quartus_py scripts/build_sof.py

^ Those instructions make no sense and have no context. ^

[niosv-shell] D:\altera\kits\Max10_Nios_v> quartus_py scripts/build_sof.py
sys

Traceback (most recent call last):
File "scripts/build_sof.py", line 66, in <module>
generate_qsys = subprocess.Popen(["qsys-script","--script={}".format(qsys_tcl_dir),"--quartus-project={}".format(qpf_dir)], stdout=subprocess.PIPE, stderr=subprocess.STDOUT,cwd=cwd_1)

That's OK! I did the usual qsys and qpf with the gui and it still works thankfully.

From the readme file:

c. Creating the bsp, build software sources and download elf
- To create software app with HAL OS, run the following commands in the terminal:
> niosv-bsp -c --quartus-project=hw/<>.qpf --qsys=hw/<>.qsys --type=hal sw/bsp_hal/settings.bsp

[niosv-shell] D:\altera\kits\Max10_Nios_v> niosv-bsp -c --quartus-project=hw/top.qpf --qsys=hw/sys.qsys --type=hal sw/bsp_hal/settings.bsp

Example Commands
----------------
Creating a BSP
* niosv-bsp -c -t=hal -p=top.qpf -r=top -s=sys.qsys bsp/settings.bsp

Updating a BSP
* niosv-bsp -u -e="set_setting hal.make.cflags_optimization -O3" bsp/settings.bsp

Generating files in the "bsp" folder for an existing BSP settings file
* niosv-bsp -g -b=bsp settings.bsp

Exporting a BSP as a TCL script
* niosv-bsp -q -E=bsp.tcl bsp/settings.bsp

Re-creating a BSP with a TCL script
* niosv-bsp -c -t=hal -p=top.qpf -r=top -s=sys.qsys -x=bsp.tcl bsp/settings.bsp

[niosv-shell] D:\altera\kits\Max10_Nios_v> niosv-bsp -c -t=hal -p=top.qpf -r=top -s=sys.qsys bsp/settings.bsp
2024.04.03.14:42:10 Error: Unrecognized switch <b>p</b>
2024.04.03.14:42:10 Error: Unrecognized switch <b>r</b>
2024.04.03.14:42:10 Error: Failed to validate switches.

So, at this point the instructions don't work, and the example from the program's own help text is gibberish.

MY QUESTION IS:

DO YOU HAVE INSTRUCTIONS AND PROGRAMS THAT WORK?

CAN I GET THEM?
