Hello, i'm trying to install "Player Limit Remover Linux 1.2.1 (TF2)"

I read the "running a plugin" & think i did it right. I'm not sure what folder i put the plr.so file in.

also: below is what my .vdf file looks like... am i all wrong here?... any help would be great.

Code:
"Plugin"
{
        "file"  "../tf/addons/plr.so"
}
