How to add DProto to handle legacy Half Life clients?

[marquisexb13]

How can I add dproto to this container so that I can create a server that can handle legacy Half Life (non-steam) clients? I tried following the directions from dproto, but couldn't seem to get it to work.

Please provide more specific reproduction steps, ie what have you tried, what works, what doesn't work, etc. If you are trying to modify the server directories take a look at the advanced setup guides at the bottom of the README. The more details you can provide with what you are trying to do the better.
