Obfs4proxy How to use?

Hi all.
I recently discovered a very interesting package in the openwrt repositories. This is obfs4proxy.
But the problem turned out to be that there is no documentation for it. No example config. and articles on its use.
I would like to test it with OpenVPN. And single mode like
iptables -t nat -A PREROUTING -p tcp -j REDIRECT --to-ports 10000

I am using TP-Link TL-WDR4300 v1 on OpenWrt 21.02.2
obfs4proxy Installed. But I did not find any config files on my router.

root@router:~# opkg files obfs4proxy
Package obfs4proxy (0.0.13-1) is installed on root and has the following files:

Just that. One executable. No config file whatsoever. I want to use it to build a Tor bridge so I was looking for it as well.

Here is the obfs4proxy config file for a Tor bridge in archlinux. It's better than nothing.
